Clariant, a producer of specialty chemicals, is showcasing the added sustainability value of its Exolit halogen-free flame retardants to composite manufacturers at CAMX 2014, Booth 3189.

Clariant is featuring advanced Exolit flame retardants for epoxy and unsaturated polyester resins, as well as engineering plastics.

It offers halogen-free Exolit flame retardants for gel coatings and formulations within the composite itself, often performing at lower dosage than comparable solutions.

Clariant says they can be used for demanding requirements for heat release, smoke density, smoke toxicity and spread of flame.

Exolit support composites in achieving the segment’s high flammability requirements of low Fire, Smoke, and Toxicity (FST) numbers, mainly focused on ISO 5658-2, ISO 5659-2 and ISO 5660-1.

At CAMX 2014, Clariant will focus on the transportation industry to reinforce these benefits.

Furthermore, Exolit halogen-free systems can be used for composite applications which have to fulfil the requirements of the recent European standard for the railway sector – EN 45545 Part 2.

“Halogen free systems featuring intumescent formulations based on Exolit APP are proven to obtain low smoke density numbers (DS4) and smoke toxicity numbers (CIT) for thermoset composites,” Clariant informs.

“Combining halogen-free, efficient dosage, and excellent flammability performance, Exolit flame retardants contribute to sustainability,” says Frank Osterod, Technical Manager Thermoset Applications, Clariant.

“Clariant goes the next step in delivering efficient and effective fire protection with more environmentally friendly flame retardants that promise low emission,” it explains.

Its unique phosphorus flame retardant Exolit OP and ammonium polyphosphate Exolit AP together support a wide range of composite applications. (AR)
