FlameTec ® Fire Retardant Plastics
Specifications & Availability
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.
