PURPOSE: To obtain the titled composition having small linear expansion coefficient of the molded article, high resistance to thermal deformation, excellent physical properties such as impact resistance, and good moldability and appearance of the molded article, and suitable for rainwater guttering, etc., by compounding a vinyl chloride resin with short glass fibers, an inorganic filler, glass beads, and a modifier. n CONSTITUTION: (A) 100pts.(wt.) of a vinyl chloride resin is compounded with (B) 5W30pts. of short glass fibers (e.g. chopped glass fibers of 0.05W3mm long, preferably surface-treated with coupling agent), (C) 10W50pts. of an inorganic filler (e.g. ultrafine calcium carbonate), (D) 5W30pts. of glass beads (having particle diameter of 50W100μ and preferably surface-treated with a coupling agent), and (E) 5W20pts. of a modifier selected from chlorinated polyethylene, ethylene-vinyl acetate copolymer, ABS and MBS. n COPYRIGHT: (C)1985,JPO&Japio |
