Officials of nylon producer Ube Industries Ltd. introduced at NPE 2003 in Chicago its new Sunbesta composite designed for automotive fuel line systems, and a nylon 12 compound.
Ube worked with Asahi Glass Co. Ltd. to develop a two-layer fuel system application that the two Toyko companies said combines the strength of Ubesta nylon 12 resins with the barrier properties and chemical resistance of the fluoropolymer ethylene tetrafluoroethylene.
Fuel lines made with Sunbesta maintain adhesion between layers, with no need for a separate adhesion layer. A modified Fluon ETFE material is used as the inside layer.
Ube also said its new Ecobesta composites for fuel lines use nanocomposites - extremely fine, clay particles dispersed into a nylon matrix.
Also, the firm said its new Ubesta XPA is a polyamide elastomer-based nylon 12 combined with a soft polyether. XPA offers improved resistance to water absorption, low bleeding and adhesion to thermoplastic polyurethanes. XPA also is four times as durable as conventional polyamide elastomer for flexural fatigue properties, Ube said.
Kaz Takahashi, president of Ube America Inc., said the company's new nylon 6 factory is nearing completion in Castellon, Spain. Production is to begin in 2004.
