PROPYLENE RESIN COMPOSITION

摘要

PURPOSE:To obtain a molded product good in dimensional accuracy with hardly any warpage while maintaining a high strength and rigidity which are characteristics of glass-fiber reinforced polypropylene. CONSTITUTION:A propylene resin composition is characterized as follows. The aforementioned resin composition is composed of (a) 100 pts.wt. polypropylene- based resin, (b) 1-25 pts.wt. polypropylene in which (b) maleic anhydride in an amount within the range of 0.2-2wt.% is grafted, (c) 5-100 pts.wt. glass fiber having 3-20mum average fiber diameter and 1-25mm average fiber length and (d) 1-75 pts.wt. chaff having 50-1000mum average grain diameter.
