| 摘要 |
<p>The present invention relates to a highly abrasion-resistant and thermoplastic polyurethane elastomer with low hardness. More specifically, the highly abrasion-resistant and thermoplastic polyurethane elastomer is obtained by polymerizing a compound including polyol, active hydrogen, an acid group or an ionomer compound of which an acid group is neutralized, polydimethyloxane including a hydroxyl group, a silane coupling agent, a cross-linking low molecular compound, a catalyst, and diisocyanate. The highly abrasion-resistant and thermoplastic polyurethane elastomer has a hard segment content of 15-25% and hardness of 75A or less, and has excellent gripping properties and mechanical properties.</p> |
