FOAMED POLYURETHANE ELASTOMER RAW MATERIAL, FOAMED POLYURETHANE ELASTOMER, AND PRODUCTION METHOD FOR FOAMED POLYURETHANE ELASTOMER

摘要

This foamed polyurethane elastomer raw material includes a polyisocyanate component (A) and a polyol component (B). The polyisocyanate component (A) includes a prepolymer of: 1,4-bis(isocyanatomethyl)cyclohexane (A1); and a polyether diol (A2) that has, as a main chain, a C3 or C4 straight-chain oxyalkylene group. The polyol component (B) includes: a macropolyol (B1) that includes at least 90 mass% of a polyether diol that has, as a main chain, a C3 or C4 straight-chain oxyalkylene group; and an alkane polyol (B2) that has a C2–6 straight-chain or branched alkylene group.
