RAMP MOLDED BODY OF HARD DISK

摘要

PROBLEM TO BE SOLVED: To provide a ramp molded body of a hard disk having a mechanical physical balance that a polyacetal resin has and excellent heat stability and excellent in heat stability after washing, dimensional stability after washing and an abrasion loss after washing which are peculiar to the ramp molded body. SOLUTION: The ramp molded body of the hard disk is composed of a polyacetal resin composition containing 0.001 to 0.03 pts.mass talc (B) having >10μm and <20μm average particle diameter to 100 pts.mass polyacetal resin (A).
