, according to Japanese patent JP2009035604 topic above polyurethane elastomer is made of polyurethane, including hydrolysis alkoxy polysiloxane and produce acid agent by hot molding. 0.5 mol, 2 and 1.1 mol, polytetrahydrofuran diphenyl methane diisocyanate, NCO pre polymers made of end, reaction with 0.4 mol, 1, 4 - butanediol, made 1310 g of polyurethane, and another 190 g phenyl silane homopolymer and 10 top oxygen radicals designed.the gn - (three oxygen fluorine methyl sulfonyl) succinimide mixing, kneading, molding, and then heated to 100 degrees Celsius for 20 hours, for a quick elastomer. The elastomer tear degree (JIS K6301) 25 degrees Celsius to 710 KGF/cm3, tensile elongation was 660%, the bending test result is 9.1 mm, softening temperature (JIS K 7206) to 185 degrees Celsius.
