Phosphate flame retardants keep pace with needs of transport sector


Clariant (Muttenz, Switzerland) says it is making fire safety and sustainability a realistic and achievable goal for transportation applications with its cost-efficient, non-halogenated flame retardant solutions. Exolit AP ammonium polyphosphate-based and Exolit OP phosphinate-based flame retardants for thermoset systems reportedly address the key challenges of modern vehicle manufacture, with its increasing trend toward lightweight structual parts.

These 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, and in achieving greater cost-efficiency without compromising on fire protection and hazard levels. Their advantage reportedly lies in their effectiveness for composites and laminates, which enables very low concentrations to be used, while at the same time meeting stringent flammability requirements.

"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."
