GLASS FIBER REINFORCED RESIN COMPOSITIONS

摘要

A glass fiber reinforced resin composition comprises by weight: (a) 30 to 98 parts of crystalline propylene polymer; (b) 2 to 30 parts of glass fiber having an average fiber diameter of 10 mu or less and amount of deposited binder of from 0.01 to 0.3%; (c) 0 to 35 parts of ethylene-based rubber; (d) 0 to 30 parts of inorganic filler selected from talc, mica, calcium silicate and glass powder; and (e) 0 to 10 parts per 100 parts of the sum of the components (a) to (d) of pigment comprising a coloring and a dispersing component, the proportion of a coloring matter having a Mohs hardness of 3.5 or more in the coloring component being less than 30% by weight. The composition has superior high temperature stiffness, appearance and pelletizability, and articles moulded therefrom have satisfactory warp characteristics even on re-heating and satisfactory impact strength.
