What are flame retardants?

How do they work?

Flame Retardants Interrupt the Fire Cycle

Three ingredients of a fire:

A fuel source

An oxygen source

An ignition source

Flame retardants work by one ofthree mechanisms

Interruption of radical mechanismof combustion process in the gasphase

Reaction in the solid phase toform a carbonaceous char which

serves as a barrier between fueland the heat and oxygen source

Endothermic processes, such asrelease of water, to remove theheat from the reaction

Source: European Flame Retardants Association, www.cefic-efra.com

Take away one (or more) of

these and the fire can be

delayed/prevented

Most Widely Used Flame Retardants Types

Mechanism Flame Retardants Types Uses & Limitations

Gas phase,Free radicalquenching

Halogenated FlameRetardants

Brominated FRs

Chlorinated FRs

Halogenated polymers

Antimony Synergists

Most versatile class of flame retardant Used widely used in thermoplastics,

epoxy thermosets for printed wiringboards, polyurethane foams, polyesters

Only option for many olefinic and styrenicpolymers uses

Often used with Antimony trioxide

synergist

Condensedphase, Charforming

Phosphorus and Nitrogencontaining flameretardants

Phosphates, Melaminephosphates

Ammonium

Polyphosphates Melamine Cyanurate

Typically effective in oxygen or nitrogencontaining polymers such aspolycarbonate, polyesters, polyamidesand epoxy resins

Often used with synergist to promote charformation, e.g. cyanurates

Phosphate esters used in PC/ABS Phosphates provide FR plasticizer for PVC

Endothermic

Metal Hydrates

Aluminum Trihydrate

Magnesium Hydroxide

Use at high loadings

Wire & cable, coatings, rubber,thermosets

Less use in engineered plastics

YOUR SUSTAINABLE SOLUTION FOR POLYOLEFINS & STYRENICS

Performance comparisons for Emerald InnovationTM 1000 in

Polyolefins and Styrenics demonstrate comparable efficiency at

similar load levels over DE-83R and Firemaster® 2100R

The polymeric nature of Emerald InnovationTM 1000 makes it more

sustainable than other brominated flame retardants used in

Polyolefins & Styrenics, making Emerald InnovationTM 1000 the best

choice when developing a sustainable product portfolio

WHY THE NEED FOR ATO ALTERNATIVES

Antimony trioxide (ATO) is typically used as a synergist witharomatic brominated flame retardants (BFR) in plastics

ATO functions via the formation of flame quenching antimony tri-

halides through a gas-phase mechanism. It is not absolutelynecessary but makes the system more cost effective

Alternatives to ATO are sought due to:

I. Cost volatility of antimony metal

II. Higher cost of ATO

CONCLUSIONS

Performance comparisons for Emerald Innovation™ 1000 in polyolefins and

styrenics demonstrate comparable efficiency at similar load levels over DE-

83R™ and Firemaster® 2100R

Emerald Innovation™ 1000 provides higher multi-axial impact strength than

other polymeric brominated flame retardants tested

Evaluation of metal salts and modified clays show great potential to

significantly reduce the use of high cost ATO in polyolefins whilst maintaining

flammability performance

HIPS formulations containing Emerald Innovation™ 1000 & PPE exhibits V-0

performance without ATO

In PC/ABS blends Emerald Innovation™ 1000 exhibits V-0 without ATO over a

wide range

Fire Safety of Polystyrene Foam Insulation

Polystyrene foam insulation provides many advantages

Lightweight, Rigid, Durable and Reusable

Excellent structural properties and moisture resistance

No mold growth, No microbiological degradation

Manufactured by two processes

Expanded Polystyrene foam (EPS – via styrene monomer)

Extruded Polystyrene foam (XPS – via polystyrene resin)

Must comply with stringent fire codes

EN ISO 11925-2

German DIN 4102 B2

The polymeric structure of Emerald Innovation™ 3000

renders it not readily bioavailable*

, thus addressingthe environmental concerns that threaten the

sustainability of many current products.

Emerald Innovation™ 3000 is an efficient, sustainable

replacement for HBCD requiring minimal modification

to current formulations or production processes.

Applicable fire safety standards covering polystyrene

foam insulation can be achieved with Emerald

Innovation™ 3000.

Synergists commonly used for EPS and XPS production

are compatible with Emerald Innovation™ 3000.

Our strategy of greener innovation provides you with proven,

sustainable alternatives

Experimental Approach

Several combinations of primary and secondary antioxidants in combination

with an epoxy novolac resin were evaluated.

All formulations were run on a single screw extruder for multi-pass evaluation in

Polystyrene Nova PS1600 @ 200ºC.

Pellets from extrusion pass 1, 3 & 5 were set aside for melt flow and color

determination on molded plaques.

The results show that a combination of AO1, P1 and E1 gives the best color andmolecular weight retention in XPS foam.

This optimized formulation is available from Chemtura as a non-dust blend (NDB1).

NDB® technology offers superior compositional control, better hydrolytic

stability and improved industrial hygiene

Stabilization in XPS Conclusions

Emerald InnovationTM 3000 is a highly efficient firesafety solution for XPS foam insulation.

An optimized stabilizer solution has been developed

for XPS containing Emerald InnovationTM 3000.

An optimized stabilizer formula is available fromAddivant as a non-dust blend

Non-dust blend technology combines multiple

additives into a single dust-free solution offering

improved productivity, industrial hygiene,

and shelf life.
