Title:
A conductive polyacetal resin constituent and its forming object
Document Type and Number:
Japanese Patent JP6054811
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a polyacetal resin composition which is excellent in conductivity and toughness, little contaminates a metallic mold in long-term continuous molding, and the conductivity of which little changes even when the polyacetal resin composition is stored for a long period of time in a melted state and then is injection-molded.SOLUTION: There is provided the polyacetal resin composition which contains at least a polyacetal resin (I), carbon black (II), and an epoxy compound (III). A content of the carbon black (II) is 5-30 pts.mass based on 100 pts.mass of the polyacetal resin (I). The polyacetal resin composition has a volume resistivity of 10to 10Ω cm and a nominal tensile strain at break of 15% or more, and both of amounts Aand Aof formaldehyde generation measured by a specific method are 100 ppm/min or less.
