RESIN COMPOSITION FOR PROFILE EXTRUSION MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a resin composition which does not cause fine splits on its molded item by blending a lignocellulose or cellulose material, a polyolefin resin, a specific amount of polytetrafluoroethylene and a specific amount of an alkyl (meth)acrylate polymer. SOLUTION: This resin composition contains 0.1-1.5 wt.% of polytetrafluoroethylene and 0.05-4.5 wt.% of an alkyl (meth)acrylate polymer. Preferably the resin composition contains not less than 20 wt.% of (A) a lignocellurose or cellulose material. Preferably the material (A) is (B) an esterified lignocellulose or cellulose material. Preferably the material (B) is a maleic acid-modified wood powder obtained by carrying out addition- esterification of a wood powder with maleic anhydride. A polyolefin to be used is preferably a mixture of a polypropylene of an MFR of 0.1-200 g/10 min at 230 deg.C and a polyethylene of an MFR of 0.01-200 g/10 min at 190 deg.C.
