Polyamide resin composition, useful for making fuel pipes in cars, includes shock-resistant component, plasticizer, thickener and rubber, has high low temperature impact strength

摘要

Polyamide composition (A) comprises (weight parts): (i) polyamide resin (30-95); (ii) shock-resistant component (1-45); (iii) nylon plasticizer (0.1-20); (iv) nylon thickener with at least two functional end groups (0.01-5); and (v) core-skin rubber component (0.5-10). Polyamide composition (A) comprises (weight parts): (i) polyamide resin (30-95); (ii) shock-resistant component (1-45); (iii) nylon plasticizer (0.1-20); (iv) nylon thickener with at least two functional end groups (0.01-5); and (v) core-skin rubber component (0.5-10). (ii) is one or more of ethylene-propylene (copolymer) rubber or ethylene-propylene-diene monomer rubber, all optionally modified by maleic anhydride; aryl methacrylate-butadiene-styrene; styrene-butadiene-styrene triblock copolymer; completely acrylic core-shell rubber; ethylene-ethyl acrylate; styrene-butadiene rubber; ethylene-vinyl alcohol; or various thermoplastic elastomers and plastomers. Independent claims are also included for the following: (a) synthetic resin products (B) prepared from (A); and (b) fuel pipe for motor vehicles prepared from (A).
