    摘要： Fire retardant sheeting materials for roofing having improved burn resistivity and are suitable for use on roofs having inclines of at least 1 inch per linear foot. These sheeting materials are prepared from a polymeric composition of matter comprising a base polymer containing at least one ethylene-propylene-diene terpolymer, the base polymer having up to about 2 percent by weight crystallinity; from about 85 to about 175 parts by weight of at least one non-combustible mineral filler per 100 parts of the base polymer; from about 30 to about 50 parts by weight of a processing material, per 100 parts of the base polymer; from about 50 to about 80 parts by weight of at least one fire retardant additive, per 100 parts of the base polymer; and from about 1.5 to about 10 parts by weight of a sulfur cure package per 100 parts of the base polymer. The composition contains at least 40 percent non-combustible materials, and the sheeting material has a limiting oxygen index (LOI) of at least 40 percent when tested in accordance with ASTM D2863-91. A method of covering a roof comprises the steps of applying layers of the fire retardant roof sheeting material prepared from the polymeric composition of matter, to the roof being covered, overlapping adjacent edges of the roof sheet material, and adhesively seaming the overlapped layers of the roof sheet material together to form a continuous roofing membrane.

    摘要： Vulcanizable elastomeric roof sheet materials for roofing having improved adhesion performance and prepared from a polymeric composition of matter comprising at least one polymer selected from the group consisting of polyolefins prepared from monomers containing at least two carbon atoms and mixtures thereof, the polymer having a crystallinity of up to about 2 percent by weight; about 20 to 125 parts by weight of one or more mineral fillers per 100 parts of the polymer, about 50 to 110 parts by weight of one or more black-type fillers per 100 parts of the polymer; and from about 50 to 70 parts by weight of a processing material per 100 parts of the polymer and having improved peel adhesion to itself using commercially available bonding and lap- splice adhesives. A method of covering a roof comprises the steps of applying layers of vulcanizable elastomeric roof sheet material prepared from a vulcanizable polymeric composition of matter, to the roof being covered; overlapping adjacent edges of the layers; and adhesively seaming the overlapped edges of the layers together to form an acceptable seam. The composition of matter is devoid of any flame retardant rubber chemical additives, heavy metals, oxidants and halogen-containing polymers.

    摘要： EPM and/or EPDM compositions exhibiting superior green strength as compared to conventional EPM/EPDM compositions are attained by adding, along with the rubber curing agents and various conventional additives as desired, colemanite and/or alumina trihydrate. Colemanite, alumina trihydrate or a mixture of the two have unexpectedly been found to enhance the green strength of EPM/EPDM compositions prior to vulcanization. The green strength promoters of this invention utilized in EPM/EPDM rubber compositions allows for faster mixing (shorter mixing cycles) and improved processing rates, such as faster calender throughput rates, to be achieved.
