Clariant is making fire safety and sustainability a realistic and achievable goal for transportation applications with its non-halogenated flame retardant solutions.
Clariant says its high-performance Exolit AP Ammonium Polyphosphate based and Exolit OP Phosphinates based flame retardants for thermoset systems address the key challenges of modern vehicle manufacture.
According to Clariant, Exolit flame retardants for unsaturated polyester and epoxy resins support the aviation, road, rail and shipping sectors in fulfilling today’s stricter flammability requirements, meeting environmental targets through the use of materials with corresponding health and environmental profiles. It explains that the advantage lies in the effectiveness for composites and laminates, which enables very low concentrations to be used, while at the same time meeting stringent flammability requirements.
Clariant explains that Exolit is available for sole use or as synergistic formulations with aluminium hydroxide (ATH), and enables thermoset resins used in fiberglass reinforced composites to reach high flammability requirements and fire standards such as under the new EU wide railway standard EN 45545-2 for interiors.
Furthermore, Clariant claims Exolit grades can be used to formulate intumescent (gel)-coats which drastically improve the fire endurance of the whole composite part. Exolit flame retardants are suited to traditional hand lay-up process, as well as pultrusion and other advanced techniques.
“The transport sector is faced with a number of rising challenges as stricter flammability and emissions requirements meet the trend toward lightweight parts and demand for manufacturing cost efficiency,” comments Adrian Beard, Head of Marketing Flame Retardants at Clariant. “Clariant’s halogen-free, sustainable retardants are able to achieve high flammability requirements and therefore present effective, efficient alternatives to materials such as decabromo diphenylether (Deca-BDE) for rolling stock, airplanes and beyond.”
