GENERAL DESCRIPTION In today's high technology industries, billions of dollars are invested in clean rooms to protect expensive equipment and their processes from becoming contaminated by air borne micron-size particles. Fires, even those small enough to pose no danger to the facility, can be disastrous to the integrity of the clean room itself.
The Flametec® family of Fire Retardant plastics have been specially formulated to provide protection against the spread of fire or flames. All of the materials shown below are listed with FM Global (formerly Factory Mutual Insurance Company) as compliant to FM4910 requirements. When FM4910 listed materials are used for construction in an area, fire suppression systems are not required.
(see also our Fire Safe Plastics Overview for details)
GENERAL PROPERTIES The Flametec® family of Fire Retardant plastics offer essentially the same mechanical, thermal, and electrical properties as their non-flame-retardant counterparts. Consult the appropriate datasheet (see links below) for comparative information.
