TPEE has the characteristics: ⒈ good creep resistance, impact resistance and fatigue properties. ⒉ high impact strength and good low temperature flexibility. ⒊ temperature rises to maintain good performance time. ⒋ good resistance to chemicals, oil, solvent and weather. ⒌ high tear strength and high abrasion performance. Dust polyester elastomer TPEE shaft relative to the application of chloroprene rubber in the dust cover has the following advantages: a, to reduce the weight of 50%, 90% shorten the molding cycle b, excellent chemical resistance and fatigue resistance c, centrifugal low expansion rate d, recyclable e, ozone resistance TPEE what material: TPEE (thermoplastic polyester elastomer) is a block copolymer comprising polyester hard segment and polyether soft segment. Wherein the polyether soft segment and non-crystalline amorphous polyester partially crystalline polyester hard segment amorphous phase forming a crystalline microdomains act as physical crosslinking points. TPEE has rubber elasticity and strength of engineering plastics; soft segment gives it flexibility to make it like rubber; hard segment given Its processing performance, to make it like plastic; and rubber, it has a better processing performance and longer life; Compared with engineering materials, also has a high strength characteristics, and better flexibility and dynamic mechanical properties. TPEE material properties: TPEE has excellent heat resistance, the higher the hardness, heat resistance, the better; TPEE at 110 ~ 140 ℃ 10h continuous heating almost no weight loss at 160 ℃ and 180 ℃ were heated 10h, weight loss of only 0.05% and 0.1%, so TPEE use temperature is very high, higher short-term use temperature, can adapt to automobile production line baking temperature (150 ~ 160 ℃), and it is little loss of mechanical properties at high temperatures. TPEE at 120 ℃ or more, the tensile strength is much higher than TPU addition TPEE also has excellent low temperature performance, TPEE brittle point lower than -70 ℃ and lower hardness, better resistance to cold, most TPEE in - Long-term use at 40 ℃. Because of TPEE high, showing balanced performance at low temperatures, its operating temperature range is very wide, it can be used in -70 ~ 200 ℃. TPEE material applications: electronics and cable extrusion series is ideal for direct contact with the copper cable products. It exhibits good heat resistance, elasticity, creep properties and insulation properties. Applications in cables, robot, communications line equipment and other applications, for example: the hose cover, and the hydraulic hoses, pipes, sealing materials; films and components and other sporting goods, including golf epidermis; application molding materials, automobile parts , belts, hose and tube; fuel tank part, sealants, a variety of gear, keypad, phone antenna, Phos class, compression springs, pipe coating, Inline-skateroller; gears, bearings, telephone lines envelope.
