PURPOSE:To provide automobile parts having excellent stain resistance, by molding a compsn. contg. a vinyl chloride resin, a plasticizer and silicone oil. CONSTITUTION:100pts.wt. vinyl chloride resin having a degree of polymn. of 900-3,000 is blended with at least 30pts.wt. plasticizer [e.g., di-(2-ethylhexyl) phthalate] and 0.1-10pts.wt. silicone oil having a viscosity of 400-5,000cst (e.g., polymethylphenylsiloxane having a phenyl group content of not lower than 5mol%). If desired, the resulting compsn. is blended with 0.5-10wt% stabilizer (e.g., epoxidized soybean oil), a filler (e.g., CaCO3), a pigment, a processing aid, etc. The compsn. is molded into automobile parts such as side protect lace, splash pad, mudguard, etc. |
