More Information
Summary:A resin composition for automobile constant velocity joint boots having a surface hardness (Shore-D) of 34 SIMILAR 44, and obtainable by melt mixing as essential components: 100 parts by weight of polyester elastomer (A); and, for every 100 parts by weight of said polyester elastomer (A), 0.05 SIMILAR 7.0 parts by weight of organic polyisocyanate compound (B); and 0.1 SIMILAR 5.0 parts by weight of silicone compound (C). A molded automobile constant velocity joint boot molded therefrom is superior in abrasion resistance, and flexibility.
