THEOMOPLASTIC POLYURETHANE ELASTOMER WITH HIGH ABRASION-RESISTANT

摘要

The present invention relates to a low-hardness thermoplastic polyurethane elastomer having excellent abrasion resistance, and more specifically, to a polyurethane elastomer having excellent abrasion resistance, including a polyol, an ionomer compound in which a compound containing an active hydrogen and an acid group or an acid is neutralized, a polydimethylsiloxane containing a hydroxyl group, Silane coupling agent, crosslinkable low molecular weight compound, catalyst and diisocyanate to produce a low hardness thermoplastic polyurethane elastomer having a hard segment content of 15 to 25% and a hardness of 75 A or less, excellent abrasion resistance, gripability and mechanical properties.
