PROBLEM TO BE SOLVED: To prevent the surface of a sheet from being contaminated and from causing troubles due to static electricity. SOLUTION: This mold for housing sheets is obtained by using a resin composition composed of 70-90 pts. wt. polybutylene terephthalate containing the unit expressed by formula 1 in the main chain of a polymer by≥90 mol% and having an intrinsic viscosity of 0.80-1.10 in an orthochlorophenol solution and 30-10 pts. wt. carbon fibers having a volume resistivity of≤5×10<SP>-2</SP>Ωcm, an aspect ratio of≤15, and a number-average fiber length of≤100μm. This mold is molded substantially without using a lubricant, a parting agent, etc. COPYRIGHT: (C)2004,JPO&NCIPI |
