Flame Retardants. A Changing Landscape” – Video Transcript
– All right, good morning, everyone.
– Good morning.
– I don’t know if everyone can hear me.
Can you hear me?
All right, I’m James, and this is Callum.
We’re from a company
called Polymer Compounders.
We’re based in Durham.
We are an engineering
and we specialize in ABS
compounds, ASA compounds.
There we go.
PC ABS, polycarbonates,
and more recently,
our Notoxicom speciality
novel flame retardants.
– So, what is a flame retardant?
So by definition, it’s a substance
that prevents or inhibits
the outbreak of a fire,
which is not to be confused
with heat resistance,
which looks at the deformation
of the polymer under heat.
With some halogen flame retardants,
they use something called a cosynergist,
which helps their flame retardancy,
which is specifically used in FR ABS,
which we’ll touch on a bit later on
because of its serious
health concerns and toxicity.
Some common flame retardant specifications
are looking at the vertical burn test,
which is a UL-94 test.
And these three specific ratings,
V-0, V-1, V-2,
and V-0, which is the most stringent test
or stringent specification.
And it looks at the
It looks at the afterglow and
the dripping of the polymer.
So specifically with V-0,
the flame extinguishes within 10 seconds
with absolutely no dripping,
so it’s the most stringent
out of the three V ratings.
So we’re gonna look at the current
flame retardant technologies
beginning with FR ABS.
And global regulators are
becoming increasingly concerned
with halogens released from the polymer
when they’re set on fire, basically.
So the alternative to FR ABS could be an FR PC/ABS,
which uses a low melting point,
which are suspended within a polymer matrix.
I know, although this seems
like a safer alternative,
it’s becoming of increasing
concern to the ECHA,
which is the European Chemicals Agency.
– So this brings us on to the
evolution of flame retardants
starting at the bottom left
with FR ABS using brominated technologies,
moving on to the middle of FRPC ABS,
which uses a liquid-based
flame retardant package.
And then moving on to the top,
which is the polyphosphonate co-carbonate,
which is something that we think
is the future of flame retardancy,
and is also in relation to our Notoxicom,
which we’ll get onto a little bit later.
– So we’re gonna look at some
developments around the world,
articles and studies.
And I’ve already spoken about
the European Chemicals Agency.
And they’ve announced
a restrictions roadmap
for a ban on all flame
And by the end of this year,
they’re supposed to be
announcing like a roadmap.
Brominated flame retardants
are banned from display units in the US.
That was announced at the end of last year
, and from the states of
New York and Washington.
So this is coming in from the year 2024.
So they’re not gonna be using
any flame retardants whatsoever
in any of their electrical displays.
A bit closer to home in
the medical industry,
the European Healthcare Without Harm
have announced a phase-out list
from no flame retardants at
all in the medical industry.
And I want you to pay attention
to an endocrine disruption study
from Brunel University in London,
which looks at flame retardants
and how they’re affecting
sperm counts in men
and just general endocrine disruption.
– So this brings us on to the
the topic of our presentation,
which is flame retardants,
a changing landscape.
So there are growing health concerns
regarding the toxicity of
flame retardants and polymers.
The ECHA have now added
the most widely used
flame retardant packages
to their list of substances of concern,
also known as the CORAP list.
– Part of this CORAP list.
TBPA, which is used in FR ABS,
is becoming of increasing concern,
not also due to its endocrine disruption,
but it bio-accumulates at the surface
and it’s toxic when it’s burned.
And this is suspected of causing cancer.
This is from the ECHA’s own website.
So this eventually will be banned.
– So, the natural progression
from FR ABS technologies
is FRPC ABS technologies.
Unfortunately, this is
also a risk of being banned
due to the health concerns
regarding the endocrine
disruption of the chemicals used.
And essentially, it will be
removed from the market as well.
– So, one of the chemicals
James was discussing was TPP,
also known as triphenyl phosphate.
And this is one of the chemicals
that’s suspected of endocrine disruption,
again, sourced from
the ECHA’s own website.
– But it’s not all doom and gloom.
superior halogen-free flame retardancy,
that do not bio-accumulate,
and a more favourable toxicity profile.
– Notoxicom, the world’s first UL-94 V-0
at 0.8 millimetres is
a halogen-free PC ABS
or an FRPC ASA
As we discussed before
the different V ratings.
Notoxicom, the UL-94 V-0,
so the best rating at 0.8 millimetres,
which is really, really thin.
So now, we’re gonna compare and contrast
the different flame retardant technologies
beginning with halogenated
And although, so the top
right-hand corner, the box,
these are polymeric
halogenated flame retardants,
which use brominated technology.
And although they don’t
migrate from the host plastic,
they’re toxic when they’re burned.
And now, to the bottom right-hand corner,
TBBPA, which we spoke about.
These are the worst of the worst.
They bio-accumulate, they’re toxic,
They migrate from the host plastic,
suspected of endocrine
disruption causing cancer.
We don’t want to be using these.
In the bottom left hand corner,
although some PC ABS flame
are branded as halogen-free,
because they use small molecules,
they still migrate from the host plastic.
This is where we keep talking
on about endocrine disruption.
It’s the migration of these chemicals
through to the surface of the polymer.
It does not migrate or bio-accumulate
and has a favourable toxicity profile.
– So this brings us to the
smoke inhalation statistics.
The number one cause of death
related to fires is smoke inhalation,
with an estimated 50 to
80% of all of these deaths
being caused or linked
to smoke inhalation.
In sufficient high concentrations
over a long enough period of time,
the inhalation of smoke
can create hazardous health conditions
for people who are exposed to it.
So this brings us on nicely
to our Notoxicom smoke toxicity test,
excuse me for fumbling.
The Notoxicom has passed
the stringent aviation
And if you can look at the bottom left
sort of towards the bottom of the screen
where the big green yes is,
you can see that the data shows
that it’s well below
the minimum requirements
needed to pass.
– We’ll look at some other
advantages of Notoxicom.
There’s no drops in heat
or strength performance,
as with other flame retardant grades.
It’s a lower density, which
means it saves on the material.
And as we’ve already spoken about,
it’s low smoke and low toxicity.
Or no toxicity, I should say, no toxicity.
– So, here in this example,
here is one of our customers.
The representative from
Super B, Marten Zilvold,
has been enjoying the greener credentials
of switching to Notoxicom,
one of which has allowed
them to use less material
by dropping a hot runner
within their system.
And also, it is used in a
lithium-ion battery application.
I almost missed that point.
– If you pop over to our stall,
a stand at B-26,
you can see the actual battery
application on our stand.
So I don’t know
whether you want to have a
go at scanning the QR code,
but if not,
you can pop over to our stand at B-26
and grab the actual data sheet.
It gives you a bit more information,
but it’s a high flow,
and with excellent complex
It’s got good heat
performance, excellent impact.
As we’ve already mentioned,
it’s halogen-free and V-0,
and it has excellent
glow wire flammability
at 960 degrees,
which makes it perfect for
Just waiting for a second
’cause I could see a few
people scanning the QR code.
– Oh, great.
So Notixocom B6000 was
tested under lab conditions
to see how it compares to
standard FRPC ABS technologies.
It was tested under both glow wire
and comparative tracking index.
The results from the conditions show
that in both tests,
it didn’t lose any of the performance
in comparison to the FRPC
ABS standard technology.
– And just another reminder,
it’s glow wire at 960 degrees.
So here in this representation,
this is a visual of before and
after the test is taking place.
The left-hand side being
the samples before,
and on the right-hand side,
the sample furthest to the right here
is Notoxicom B6000.
As you can see,
there is a severe less amount
of charring on the samples,
significantly less amount of charring.
– Now, we’re gonna look at
the recycling robustness.
After one recycling pass,
Notoxicom still maintains its
excellent impact resistance
after one recycling pass.
The two others, the BPADP
and the RDP are other
FRPC ABS alternatives.
You can see a slight dip
in performance with B6000,
but as we move on to the V-0
rating in the next slide,
we’ll discuss it a little bit more.
– Notoxicom also maintains
its V-0 rating after recycling.
As you can see,
both the RDP test sample
and the BPADP sample,
they have both lost some of their rating
from the initial start.
So B6000 maintains its
V-0 rating throughout,
with RDP being the one that loses the most
and dropping to a V-2.
– As James has said,
RDP has lost its V-0 rating,
it’s flame retardancy, from a V-0 to a V-1.
And going back, looking
at the impact resistance,
even though BDADP has maintained
its impact resistance,
it totally loses its V-0 rating
after one recycling pass,
which means Notoxicom is
left standing on its own.
– So this brings us onto our
vertical burn demonstration
with ABS being the sample on the left,
with our Notixocom in the center,
and a general FR ABS to the right.
As you can tell from the samples,
when the flame reaches the FR ABS,
it rises up significantly more
than the Notoxicom sample in the center,
which acts almost like a barrier,
which is what its designed to do
being a self-extinguishing polymer.
It does not allow the fire to continue.
And you can also see in the FR ABS,
the black smoke that comes off the sample
is the gas that we were
referring to earlier
escaping from the polymer
as it’s being activated.
And ABS just sort of
disappears in a sea of fire.
– So, just to summarize,
TBBA, which is the main flame
retardant used in FR ABS,
it’s highly likely to be banned
due to its major health concerns,
its toxicity, and endocrine disruption.
non-halogenated FR technology,
which is with a lot of
heavy scientific data
suspected of endocrine disruption.
We’ve seen that in the Guardian newspaper,
we’ve seen that from
the ECHA’s own studies,
and we have the state of New
York and Washington as well
announcing that they’re gonna
be banning these materials.
I think that the safer alternative
is our Notixocom range,
which uses polyphosphonate
which is a greener solution
with superior mechanical properties,
V-0 rating at 0.8 millimetres,
that do not bio-accumulate,
and a more favourable toxicity profile
passing aviation small toxicity testing.
So let’s start the conversation together.
With future changes in
are you ready for a greener future?
We have a real alternative
solutions available now
and we are ready to support
your future developments.
– [Announcer] Ladies and gentlemen,
the round table discussion on the future–
– So we’d just like to
take a moment to thank
all of the key parties involved,
which involves the team at PCL
and also some of our partners
elsewhere in the globe,
some of the notable ones
being FRX Innovations,
Kedu Polymers, Super B, and of course,
assisted with the moulding
and is the moulder (indistinct).
– Thank you for listening.
– Thank you for listening.
– All right, thanks very much, gentlemen.
It makes me feel rather old
’cause when I started off,
it was antimony trioxide.
– Yeah, that’s the cysynergist in FR ABS,
which is, yeah, nasty.
– I think you were still in your nappies
when I was using that.
Okay, I think you’ve already
answered one of my questions,
what makes it different?
And you’ve said it’s non-halogenated.
Before I forget,
is your presentation
available for the audience?
– We can make it available, yeah.
– Yeah, we will do that.
– So if they come and
see you at the stand on?
– Just to answer your question there,
you said what makes it different.
You said because is it non-halogenated.
It’s not just that it’s non-halogenated
because the non-halogenated
they contain a liquid additive
that’s suspended within
the polymer matrix,
whereas ours is a full polymer blend.
– So it comes as a master
batch or something.
– No, no, no.
It’s a full polymer blend,
full polymer compound.
And its polyphosphonate
– So there’s nothing to escape.
So commonly, FR ABS,
FRPC ABS has something
in there in addition to,
whereas our polyphosphonate co-carbonate
is literally a compound.
Nothing’s come out.
– Fully polymeric.
– Fully polymeric.
And yeah, the molecular chains in there
prevent it from capturing fire.
We tried to coin the
as opposed to flame retardant.
It’s a little bit of
a nicer kind of thing,
but there was a lot of negativity
around flame retardants.
and if you’d like any more information
or you’d like to go and
collect a physical data sheet,
please pop over to our stand at B-26
and we’ll be happy to
answer any more questions
you may have.
Thanks for listening.
– Okay, before we open,
there’s some questions, I’m sure,
the audience is gonna ask.
What do you do in terms of formulation
that you need to change
if they’re approved,
I don’t know, FDA approved,
or different industries?
Do you have to assist the
clients with formulations
and going through the approval process?
– So in terms,
well, in terms of aviation,
we’re developing different
grades for different industries.
And as we’ve discussed before,
it passes smoke toxicity tests,
which are far more stringent
than any other industry.
– So we have a version of
Notoxicom called A6000,
which we’ve designed specifically
for aviation purposes.
We are also, as we’ve got B6000,
which is a great injection
We’ve also got B6303, which
is an extrusion version.
So we’re tailoring it to
each of our customer’s needs
and their desires with their material.
– Yeah, ’cause not only
are we a compounder,
We blend different polymers together.
We create our own materials as well.
We’ve got an excellent lab team
run by our technical
manager, Steven Blair, there.
So yeah, we’re developing new grades
and variations within our Notoxicom range.
– So, the sports stack.
Right, let’s open the floor to questions.
Has anybody got any questions?
I’m sure there’s gotta
be a question somewhere.
You get paid if you ask a question.
Well, thanks very much, gentlemen,
but please feel free to
approach them on the stand.
Thanks very much.
A round of applause, please.
– Thank you.
