PURPOSE:The titled resin compositions which give moldings having excellent weld strength, dimensional accuracy, etc., by compounding crystalline propylene polymers, glass fibers, wollastonite powders, modified olefin polymers, and interfacial surface-treating agents for fillers. CONSTITUTION:91.5-53wt% crystalline propylene polymer (A) with a melt flow rate of 1-80g/10min, 3-15wt% glass fibers (B), 5-25wt% wollastonite powders (C), 0.1-7wt% olefin polymer (D) modified with an unsaturated organic acid (derivative) (e.g. an acrylic acid grafted polypropylene), and a titanate, chromium or silane surface-treating agent (E) for fillers (e.g. vinyltrichlorosilane) in an amount of 0.1-7wt% based on 100wt% component C are compounded to give the titled composition. The compositions are used suitably for fans having blades provided with a connecting ring on their tips. |
