Abstract

PURPOSE: To provide an acetal resin compsn. which has high cycling properties and in which molding strains are improved, by adding a specified inorg. compd. to an acetal resin.
CONSTITUTION: At least one member selected from hydrotalcite, calcium fluoride, zirconium silicate, sodium borate, an SnO2/TiO2 composite and an SnO2/Ba SO4 composite, or together with an alkylenedi(fatty acid amide), is added to an acetal resin. A reason why the warpage of the acetal resin compsn. contg. said inorg. additive added thereto is improved in injection molding may be that ununiform shrinkage in the solidification of a molten resin by cooling causes molding strains and results in the warpage of moldings, but when said inorg. additive is dispersed, shrinkage and solidification uniformly occur. When the alkylenedi(fatty acid amide) is used together with said additive, the amide serves as a suitable dispersant for said inorg. additive, and further promotes the effect of said inorg. additive on the crystallization and the uniform shrinkage of the acetal resin.
