Patent ID: 8394879

Claim:
An elastomeric polyolefin composition comprising: (a) at least one flexible or elastomeric polyolefin polymer; (b) a sufficient amount of polypropylene homopolymer in a concentration to impart said composition to a final Shore A hardness of between 50 and 96; (c) a brominated flame retardant; (d) a hypophosphorous acid metal salt having the following general formula: (PH 2 O 2 ) n Me where Me is a metal atom belonging to the groups I, II, III, or IV of the periodic table of the elements, and n is an integer number ranging from 1 to 4 depending on the valence of the metal Me; (e) a plurality of selected additives consisting of 0% to 0.25% by weight of migratory surface modifiers which act as external lubricants, 0% to 2% by weight of tertiary sterically hindered amine ultra violet light stabilizer(s), organic pigments and colorants and/or inorganic pigments and colorants; and (f) either no filler, or a filler having a pH of less than 7.0; whereby said elastomeric polyolefin composition has a density of less than 1.0 gram per cubic centimeter and a Shore A hardness of between about 60 and 94 as measured according to ASTM D-2240, whereby the final elastomeric composition can be extrusion processed using cast film extrusion, extrusion coating onto a substrate, cross head extrusion coating onto a monofilament or multifilament yarn, calendaring, or used in a blown film extrusion process.
