A non-black roof sheeting material may be prepared from a composition of matter comprising 100 parts by weight of at least one polymeric rubber selected from the group consisting of ethylene-propylene-diene terpolymers, ethylene-propylene copolymers and other polyolefinic type polymers; from about 20 to about 300 parts by weight of a blend of at least two mineral fillers, per 100 parts of said polymeric rubber, wherein one of said mineral fillers is a reinforcing silica and wherein another of said mineral fillers is a chemically modified clay; from about 20 to about 150 parts by weight of a processing oil, per 100 parts of said polymeric rubber; from 1 to about 6 parts by weight of a sulfur cure package having at least one accelerator but being devoid of any thiuram accelerators, said cure package allowing said sheeting material to cure at about the same rate as a comparable black roof sheeting material at 160. degree. C. The non-black (white) sheeting material may form the ply of a white-on-black bilaminant roofing membrane or it may represent both the top and bottom ply of a non-black (white) polymeric roof sheeting material.

A walkway pad composition comprises 100 parts by weight of an ethylene-propylene-diene terpolymer; from about 60 to 700 parts by weight of a filler selected from the group consisting of reinforcing and non-reinforcing materials and mixtures thereof, per 100 parts of the terpolymer; from about 40 to 175 parts by weight of a processing material and mixtures thereof, per 100 parts of the terpolymer; and from about 2 to 10 parts by weight of a cure package, per 100 parts of the EPDM terpolymer, the composition being devoid of any additional polymeric components. The 100 percent EPDM walkway pad composition has better low temperature properties and superior weathering resistance, and heat aging resistance compared to other walkway pad compositions which may include other polymeric components such as natural rubber, synthetic polyisoprene, styrene-butadiene rubber (SBR), polybutadiene, and butyl (IR) rubber. Up to about 25 parts by weight of ethylene-propylene copolymers may be substituted for the EPDM terpolymers.

An orthopedic fastener assembly for stabilizing and fixing spinal column, bone sections and joints of the body. The orthopedic fastener assembly having a screw-pin anchor, a collet/inner coupling and head/outer coupling. Once assembled, the present invention has an even-lower profile, providing for multiple adjustments and enhanced flexibility, yet is easier to manufacture because of its greater tolerances than previously known assemblies.

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.
