Description:Features: 1) All grades of TPEE are block copolymers consisting of a hard segment of PBT and a soft segment based on polyether glycols 2) The polyether-ester block copolymers, also named polyester rubber, combine the desirable elasticity of rubber and the strength of engineering plastics. The soft segment features elasticity, and makes it like rubber, the hard segment features processing capability, and makes it like plastics. Compared with rubber, it has better processing capability and longer service life; compared with engineering plastics, TPEE has high strength, better flexibility and mechanical properties 3) Available grades of TPEE are grouped into 4 categories by performance: a) High-performance grades exhibit high structural strength, wide range of hardness, exceptional toughness and resilience; high resistance to creep, abrasion and flex fatigue; flexibility at low temperatures; and good retention of properties at elevated temperatures. In addition, they resist deterioration from many industrial chemicals, oils and solvents. b) Extruding and blow molding grades provide excellent melt strength for making various kinds of covers and hoses coupled with the desirable characteristics of high-performance grades c) Flame retardant grades are used for applications requiring flame retardant d) Modified grades are used as an excellent plastic modifier for blending with POM and PBT to improve the impact resilience 4) Applications: a) Automotive components: CVJ boots, airbags, air ducts, belt drive, conveyor belts, hoses and steering wheel cover b) Electrical appliance: cable jackets of grips of welding torch, elastic buttons of electrical equipment, antenna cover of wireless phone, wire and cable jackets and instrument c) Manufacturing industry: railroad tie pads, slide of elevator, high-pressure gasket, silent gears of recorder, silent gears of quartz clock and spring of cigarette machine d) Electric tools e) Sports requisites f) Modifier of PBT / PET / POM 5) ALL grades of TPEE are supplied as cylindrical pellets. They shall be dried in dehumidified hopper dryer for 4 to 6 hours at the temperatures between 80 and 110°C. New materials can blend with the recovered ones, but the added quantity shall be no more than 25% 6) Inject molding: temperature of pellets shall be 5 to 15°C higher than the product melting range, the mold temperature shall be 20 to 50°C, injection pressure shall be 60 to 100 MPa 7) Extruding and blow molding: best L/D ratio of screw shall be 24:1, the temperature of barrel shall be 5 to 10°C higher than the product melting range 8) Packaging, storage and transportation: all grades of TPEE are packaged in 25kg multiwall paper bags with a moisture barrier inner wall, can be stored at a cool, dry place for long, and transported as non-dangerous goods
