Abstract

PURPOSE:To reduce the coefficient of friction and improve wear proof by using slip sheets composed of polybutylene-telephthalate having specific surface electric resistance. CONSTITUTION:A slip sheet 5 is formed by filming polybutylene terephthalate through melt-extrusion and cutting the film. Minute grid projections 12 are formed on the slip sheet 5 by curling it like a central projected shape or arranging pyramidal recessed parts 13 on the whole surface. Conductive substances are mixed to reduce surface electric resistance to <=10<13>OMEGA/cm<2>.
