    摘要: A polyolefin rubber composition comprising (A) an ethylene/α-olefin/nonconjugated polyene random copolymer, (B) an organohydrogenpolysiloxane containing on average from 1 to less than 2 Si—H groups in a molecule, and (C) an addition reaction catalyst can be compression molded or steam vulcanized into a cured product having heat resistance and surface lubricity. The cured product is especially suited as weatherstrips and windshield wiper blades.

    摘要: The present invention is a polyolefin rubber composition containing: 100 parts by mass of (A) an ethylene-α-olefin-unconjugated polyene random copolymer; 1-100 parts by mass of (B) an organopolysiloxane having a degree of polymerization of 20 or higher and having 0 or 1-3 alkenyl groups per molecule, the organopolysiloxane being represented by the following average compositional formula (1): RaSiO(4-a)/2 (in the formula, R represents the same or different monovalent hydrocarbon groups, and a is a positive number of 1.95-2.05); 10-100 parts by mass of (C) reinforcing silica having a specific surface area of 50 m2/g or higher by the BET method with respect to 100 total parts by mass of components (A) and (B); and 1-150 parts by mass of (D) particles selected from the group consisting of specific organic resin particles, inorganic particles, and silicone powder particles. This polyolefin rubber composition can be compression molded, steam vulcanized, etc., exhibits surface slidability after curing, does not undergo reduction in mechanical properties, and has exceptional blocking resistance.
