High performance TPEE granule

We supply top quality of TPEE resin from China.

TPEE is a block copolymer who contains a hard segment of polyester and a soft segment of polyether; wherein the amorphous is formed from the soft segment of polyether and the uncrystallized polyester. Micro-crystals play a role as physical crosslinking points formed from the hard segment of the polyester. Thermoplastic polyester elastomer has the rubber elasticity and strength of engineering plastics. Soft segment gives it flexibility to make it like rubber; hard segment assigns the processing properties which makes it like plastic. Compared with rubber, it has a better processing performance and longer life; and the same high strength characteristics compared to plastic, while the flexibility and dynamic mechanical properties is better. TPEE has high strength, high flexibility, oil resistance, high temperature, radiation, dynamic mechanical properties superior to other properties;

SUNPRENE^® TPEE service temperature range :-100℃～+180℃,hardness range: 26～75D,
The available grades of SUNPRENE® TPEE are grouped into 7 categories by performance: high-performance grades, environment-friendly halogen containing fire grades, low smoke halogen-free fire grades, blow molding grades, extrusion grades, and modified grades

Data are typical.
 

The introduction of High- performance grades of SUNPRENE^® TPEE:
SUNPRENE^®TPEE are the main product of our company. They exhibit high structural strength, good creep resistance, excellent resilience, impact resistance, bend fatigue resistance, friction resistance, and dimensional stability. In addition, SUNPRENE^®TPEE has flexibility at low temperature and keep good performance at elevated temperature. They can resist many industrial chemicals, oils and solvents leading to corrosion.

The guideline of High-performance grades of SUNPRENE^®TPEE molding processing:
TPEE exhibits hydrolyzing resistance, then it doesn’t react with water in the air. Because it has a little water absorption ability, we must need to dry them before we process (although the moisture content of TPEE is less than 0.1%, extrusion and molding process is not will have a defect.), for the workpieces perfect.

In acid medium, TPEE will degrade at high temperatures. Therefore, TPEE and acid additives can’t be used simultaneously.
Before the molding process, TPEE must be dried under oven at 100~110 ℃ for 3~5h, and then processed immediately, not to let them cooled and in damp air, or to affect their performance.

Processing technology:
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.

The typical application and their pictures of High-performance grades of SUNPRENE^®TPEE
High-performance grades of SUNPRENE^®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).
