<p><P>PROBLEM TO BE SOLVED: To provide a boot for a disc brake caliper more excellent in durability, capable of stabilizing function of brake operation for a long period of time, and enabling efficient production (short time, high number yielding) as compared with the conventional boot for the disc brake caliper. <P>SOLUTION: The bellows-like boot for the disc brake caliper contains: an EPDM polymer comprising an ethylene/propylene/non-conjugated diene three-component copolymer; and an intercalation mold-releasing agent indicating non-compatibility to the EPDM polymer as main components, and the boot for the disc brake caliper comprises EPDM composition blended with 1-8 pts.wt. intercalation mold-releasing agent to 100 pts.wt. EPDM polymer. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
