Compositions roofing membrane epdm fire retardant for use in high slope roofs.

摘要

MATERIALS INNIFUGAS PLATES SHAPED ROOFS ROOF OR HAVING A BETTER Resistivity FIRE AND WILL USE IN suitable for roofs with inclines of at least one inch per foot LINEAR. THESE MATERIALS IN BOARDS ARE PREPARED BY A polymer composition of matter comprising a base polymer with at least one ethylene - Propylene Diene, the base polymer having a crystallinity of up to 2 weight percent, between about 85 and about 175 PARTIES by weight of at least one mineral filler NONCOMBUSTIBLE per 100 parts base polymer; Between 30 and about 50 parts by weight of a processing material, per 100 parts base polymer; Between about 50 and 80 parts by weight of at least one additive flame retardant, per 100 parts of the base polymer; And 1.5 to about 10 parts by weight of a cure package SULFUR per 100 parts of the base polymer. The composition contains at least 40 PERCENT OF noncombustible materials, YEL sheet material has an index LIMITING OXYGEN (LOI) of at least 40 percent when verified according to standard ASTM OF AT LEAST 40 PERCENT WHEN is verified according to ASTM D2863 - 91. Procedure for filling a deck or ROOFING OPERATIONS COMPRISING LAYERS OF APPLYING INNIFUGO sheet material prepared by polymer composition MATTER TO DECK being built, CONTIGUOUS OVERLAPPING EDGES MATERIAL pLATES COVER, AND JOINING LAYERS adhesively overlapping plates covering material together to form continuous cover membrane.
