THERMOPLASTIC POLYESTER ELASTOMER (TPEE) Arnitel for cable insulation

 

1. What is TPEE ?

TPEE (thermoplastic polyester elastomer) is a block copolymer containing polyester hard segment and polyether soft segment. The polyether soft segment and the non crystalline polyester form amorphous phase, and the hard segment is partly crystallized to form the crystalline micro region, which plays the role of physical crosslinking point. The soft segment gives it elasticity to make it like rubber; the hard segment gives it the processing performance and makes it like the plastic; compared with the rubber, it has better processing property and longer service life; compared with the engineering material, it has the characteristics of high degree of strength, and flexibility and dynamic mechanics. The performance is better. By adjusting the ratio of soft and hard segments, the hardness of TPEE can be from Shore 30-82D, whose elasticity and strength are between rubber and plastic. Because of the balanced performance of TPEE at high and low temperatures, its working temperature range is very wide, and it can be used at -70 ~ 200°c.

 

 

2. How to produce TPEE?

 

1,Injection molding:barrel temperature should be higher than the melting point of products 5~15 ℃, injecting pressure at 60~80 MPa, mold temperature at 20~50 ℃, injecting in a low speed.

2,Extruded into linear workpieces:when extruded into wire and other workpieces, barrel temperature should be higher than the melting point of products 5~10 ℃, recommended aspect ratio of 24:1, screw in medium-low speed.

 

3.What's the application for TPEE ?

 

High-performance grades of TPEE are mainly used for:
Automotive parts:Airbags accessories, after the suitcase lock assembly, door lock assembly, door handle seal ring, vibration plate, silencer gears, pipe closers, plugs, ball-end, windows seat shock, shock chassis, stone chip resistant coating chassis, etc.

Shoemaking: Sole, heel, roller skates or roller skates wheels, etc.
Electronics and electrical appliance:Welding the cable sheath, electrical flexible button, cordless phone antenna covers, wire and cable, etc.

Industrial manufacturing:Elevator slide, high-pressure washer, silencer gear, spring cigarette machines, instruments and so on. Electric tools, sports goods, plastic alloys, daily necessities (toothbrush handle).

 

 

TPEE Fire series can meet a variety of fire prevention purposes, including: electronic components, cables, hoses, sheaths, etc.

 

 

 TPEE flame-retardant series, with excellent processing performance, high toughness, fatigue resistance, and maintain excellent mechanical properties and flexibility in high or low temperatures.For the production of a variety of jacket and hose, such as: steering sheath, shock absorber jacket, dust cover, traction coupling cover, distance bellows, engine intake duct, clothing lining film, etc.
