Thermoplastic Polyester Elastomer TPEE

Transcription

1 Thermoplastic Polyester Elastomer TPEE Thermoplastic Polyester Elastomer (H 2 ) 4 [(H 2 ) 4 ]n x y hard segments soft segments figure 1 TPEE consists of fully polymerized hard and soft segments. The hard segments are crystalline polybutylene terephthalate ( made from 1,4-Butylene glycol and Terephthalic acid or Dimethyl phthalate);the soft segments are amorphous polyethers(polytetra-methylene glycol).

2 TPEE HARATERISTIS TPEE provides a winning combination for many parts and components. They give the flexibility of rubbers, the strength of plastics and the processibility of thermoplastics. They can be processed easily by conventional thermoplastic processes like injection molding, blow molding, calendaring, rotational molding, extrusion and meltcasting. TPEE is ideal for parts requiring excellent flex fatigue and broad use temperature. It is strongly resistant to tearing, flex-cut growth, creep and abrasion. Its mechanical properties provide the strength and stiffness you need, in addition to outstanding toughness. Its chemical properties make it highly resistant to hydrocarbons and many other fluids. If you have multi-part or multi-material components that could be made simpler or operate more efficiently with TPEE, we invite you to learn more about this unique thermoplastic polyester elastomer. 40D: A 40 nom. Shore D, containing non-discoloring stabilizer, low melting point, plasticiser free, high performance resin for extrusion and injection; with high impact resistance down to -40 as well as excellent mechanical properties. 55D: A 55 nom. Shore D, containing non-discoloring stabilizer, plasticiser free, high performance resin for injection molding; high flow, good impact resistance down to -40 as well as mechanical properties up to 120. TPEE APPLIATINS Take advantage of the unique combination of properties and processing productivity offered by TPEE to innovate. Use it to develop parts and products that cut cost, improve performance, reduce weight, or open new business opportunities. TPEE has already proven its performance for a wide variety of applications in automotive, electrical/electronic and various other industrial and consumer products. Some example include: Auto parts and systems: Air bag deployment door, VJ boots, air intake ducting, and various components for heavy trucks and off-road equipment Industrial products: Drive or idler belts, energy management parts, gears, hose and tubing, pump diaphragms, seals, shock- and noise-absorbing

4 Injection operation of TPEE 1.Drying: TPEE must be dried prior to processing. It is critical to ensure that the resin is dry during processing to make quality parts that would give good service performance. Moisture levels above 0.10% may seriously impair an injection operation. Drying time and temperature will depend on the initial moisture level in the material(often is % ),so we suggest the drying condition :105 /3-5hours. 2.ondition of Injection: 1140H 1155L Normal Melting Point * Typical Injection Temperature ( ) Rear enter Rear Front Head Die Screw speed (rpm) Pressure (kg/cm 2 ) Injection pressure Holding pressure Injection time(sec) Holding pressure time(sec) *1.Differential scanning calorimeter(ds)peak of endotherm
