Title:
GLASS-FIBER REINFORCED POLYETHYLENE TEREPHTHALATE BASED RESIN COMPOSITION COLORED TO WHITE
Document Type and Number:
Japanese Patent JPS60233150
Kind Code:
A
Abstract:

PURPOSE: To composition, consisting of polyethylene terephthalate, glass fibers and zinc sulfide based pigment, and colored to white without deteriorating mechanical strength nor heat distortion temperature.

CONSTITUTION: A composition obtained by incorporating (A) 35W95wt% polyethylene terephthalate based resin having 0.4W1.4 intrinsic viscosity with (B) 5W 60wt% glass fibers, preferably the chopped strand type having about 0.4W6mm length and (C) 0.1W20wt% zinc sulfide based pigment which is a white pigment containing ≥50wt%, preferably ≥95wt% zinc sulfide expressed by the chemical formula ZnS to give 100wt% total amount of the components (A), (B) and (C). The above-mentioned composition provides molded articles having sufficient strength and high heat distortion temperature by the conventional process without using the masterbatch method even in case the molecular weight of the component (A) is relatively low.
