CO-EXTRUDED, MULTI-LAYER TUBING MADE FROM POLYAMIDE AND OLEFIN POLYMER MATERIALS |
摘要 |
<p>A three-layer, co-extruded tube has (1) an inner polyamide layer, (2) a midd le layer made from (a) a modified polyolefin, (b) a broad molecular weight distribution propylene polymer material, (c) a graft copolymer made from a backbone of propylene polymer material to which is grafted a methyl methacrylate/methyl acrylate copolymer or a methyl methacrylate/methacrylic acid copolymer, and (d) an olefin copolymer rubber, and (3) an outer layer made from (a) a broad molecular weight distribution propylene polymer material, (b) a graft copolymer made from a backbone of propylene polymer material to which is grafted a methyl methacrylate/methyl acrylate copolymer or a methyl methacrylate/methacrylic acid copolymer, and (c) an olefin copolymer rubber. The tubing is suitable for fuel systems, high pressure tubing, and other tubing for automotive applications.</p> |
