Abstract: The present invention provides a multilayer tube for a transmission oil cooler. The multilayer tube for the transmission oil cooler includes a hose part having a multilayer structure. The multilayer structure includes a hollow inner-layer hose and an outer-layer hose. The hollow inner-layer hose is formed of a polyphthalamide or polyamide material. The outer-layer hose is formed of a polyamide612 or polyamide610 and is stacked on the outer surface of the inner-layer hose.

Abstract: The present invention relates to a polyamide resin composition and, more particularly, to a polyamide resin composition for an automobile radiator, prepared by mixing a polyamide resin, prepared by mixing a polyamide 66 resin having excellent mechanical strength and heat resistance with a polyamide 612 resin having excellent chemical resistance, a glycidyl reactive compatibilizer, glass fiber coated with a silane-based coupling agent, amine and silane-based crosslinking agents, phenol- and phosphate-based antioxidants, an imide hydrolysis resistance agent, and a montan-based lubricant in a predetermined ratio, thus improving heat resistance and chemical resistance simultaneously and maintaining equivalent properties to those of conventional polyamide resin compositions.
