20130221001 | RESIN-MADE FUEL INLET PIPE, AND METHOD FOR PRODUCING SAME - A resin-made fuel inlet pipe that has a light weight, excellent impact resistance, and causes no fuel leakage includes at least one resin layer comprising a resin composition containing (A) a high-density polyethylene (HDPE) or a linear short-chain branched polyethylene (LLDPE); (B) a polyethylene polymerized with a metallocene-based catalyst; and (C) a carbon black. A weight mixing ratio (A)/(B) is in a range of from 10/90 to 90/10; a content of component (C) is in a range of from 0.1 to 5 parts by weight with respect to 100 parts by weight of a total of components (A) and (B); a soft tissue (Y) comprising component (B) is inserted between linear crystalline tissues (X) comprising component (A) to expand an interval between the tissues (X); and component (C) is dispersed in the soft tissue (Y). | 08-29-2013 |
20140193597 | RESIN FUEL TUBE - A resin fuel tube is provided, which includes at least one resin layer, wherein the resin layer is made of a resin composition comprising: (A) a polypropylene prepared through polymerization with the use of a metallocene catalyst; and (B) a polypropylene material having a melting point of 137° C. to 160° C., the resin composition having a mixing weight ratio of the components (A) and (B) satisfying (A)/(B)=95/5 to 50/50, wherein the resin layer has a structure such that a soft structural portion (Y) of the component (A) intrudes into a space between crystalline structural portions (X) of the component (B). Therefore, the resin fuel tube is light-weight, excellent in impact resistance and heat resistance, free from fuel leakage, and usable in an atmosphere at 130° C. or higher, for example, in an automotive engine room or the like. | 07-10-2014 |
20150056393 | RESIN COMPOSITION FOR FUEL TUBES, AND FUEL TUBE - A resin composition for fuel tubes includes an aromatic polyamide resin (A), an aliphatic polyamide resin (B), and an aminoethylated acrylic polymer (C), wherein a polyamide resin obtained by an amine-exchange reaction between (A) and (B) is contained, and at least one selected from the group consisting of the polyamide resin, (A), and (B) is bound to (C). The resin composition for fuel tubes can achieve both resistance to calcium chloride and fuel barrier properties at the same time and has excellent molding processability. | 02-26-2015 |
