TPX® RT31 TPX® RT31是一种聚甲基戊烯共聚物(PMP 共聚物)材料,。 该产品在欧洲或亚太地区有供货,加工方式为:注射成型。 TPX® RT31的主要特性有: 坚硬 无气味/无味道 TPX® RT31的典型应用领域为:食品接触应用 TPX® RT31 TPX® RT31是一种聚甲基戊烯共聚物(PMP 共聚物)材料,。 该产品在北美洲有供货,加工方式为:管路挤出成型、挤出、纤维(纺纱)挤出、型材挤出成型或注射成型。 TPX® RT31的主要特性有: 高刚度 无气味/无味道 TPX™ RT31 TPX™ is a 4-methylpentene-1-based olefin copolymer. TPX™ has a unique molecular structure. Although TPX™ is a crystalline olefin polymer, it shows transparency. Because of its excellent heat-resistance, release property and chemical resistance, TPX™ is used for industrial materials, including mandrels and sheaths in the manufacture of high-pressure rubber hose, mold cups to create LED light and other applications such as release film on FPC manufacturing process and release paper in the manufacture of synthetic leather. Furthermore, TPX™ possesses a lowest density among thermoplastic polymers and then provides the molded articles with lower weight. This leads to reduce the environmental load for transportation. It is also noted that TPX™ is a halogen-free polymer denoted as environmentally-friendly material. TPX™ is also used for food-related applications such as food wraps, food preservation packs, baking carton and microwave oven tableware TPX™ RT31 TPX™ RT31 is a Polymethylpentene Copolymer (PMP Copolymer) material. It is available in North America for extrusion, fiber (spinning) extrusion, injection molding, pipe extrusion, or profile extrusion. Important attributes of TPX™ RT31 are: High Stiffness Low to No Odor/Taste |
