Glass fiber-reinforced polyamide resin composition

Abstract

Abstract PURPOSE:To provide a compsn. which has excellent mechanical properties and suffers little environmental stress cracking caused by metal halides, by mixing a glass fiber with a mixture of two aliph. polyamides having a specified ratio of the number of methylene groups to that of amide groups and a specified relative viscosity ratio. CONSTITUTION:10-60wt% glass fiber is melt-kneaded with 90-40wt% polyamide resin compsn. which consists of 10-90pts.wt. aliph. polyamide (A) in which the ratio of the number of methylene groups to that of amide groups in the main polymer chain is 4-5, and 90-10pts.wt. higher aliph. polyamide (B) in which the ratio of the number of methylene groups to that of amide groups is 6-11 and has a ratio of the relative viscosity of A to that of B of 1.16-2.70. Optionally, other polymers and additives such as inorg. filler, colorant, antioxidant, thermal stabilizer, ultraviolet light absorber, antistatic agent, lubricant, plasticizer, flame retarder, etc. may be added to the above compsn. according to purpose, so long as the desired properties are not deteriorated.
