Thermoplastic polyester elastomer (TPEE) is a block copolymer containing polyester hard segment and polyether soft segment. Among them, polyether soft segment and uncrystallized polyester form amorphous phase polyester hard segment to form crystalline microzone, which plays the role of physical crosslinking point. TPEE soft segments with rubber elasticity and engineering plastic strength provide elasticity like rubber; Hard segments confer processability like plastic; Compared with rubber, good processing performance, long service life; Compared with engineering materials, it also has the characteristics of high strength, softness and dynamic mechanical properties are better, then, let's understand the detailed introduction of TPEE thermoplastic polyester elastomer!

TPEE

Characteristics of TPEE

Excellent creep resistance, fatigue resistance, high impact resistance and excellent elasticity at low temperatures, strong chemical resistance, excellent heat resistance of oils and various solvents (160); Good adhesion forming with excellent mechanical properties ABS, PC, PVC, etc. Simple processing, excellent coloring and excellent recycling.

The main application areas of TPEE

Widely used in the automotive industry, electronic and electrical industry, industrial parts, sporting goods and other fields, such as automotive air bag cover, automotive intake pipe, pulley block, high and low temperature resistance wire cover, high level silent gear production.

Application and advantages of TPEE

1) Antenna

Its excellent resistance to external environment, ozone resistance, ultraviolet resistance, weather resistance, can reduce the loss of signal reception, excellent feel is the choice of car antenna and mobile phone antenna.

2) Engine intake pipe

The method of processing the intake pipe is usually 3-D or negative pressure blowing, which is a relatively simple and low-cost molding technology for making long air pipes with molds. Through simple installation and processing technology, TPEE is widely used in the production of this part. Blow molding can reduce the number of parts and the installation process, making the cost of parts smaller than traditional rubber.

3) drive shaft dust cover

TPEE polyester elastomer has the following advantages for the application of neoprene rubber in dust cover: a, 50% lightweight, 90% reduction of forming cycle b, excellent drug resistance and fatigue resistance c, low centrifugal expansion rate d, recyclable e, ozone resistance

4) Airbag box

The KEYFLEX TPEE-S series products are used in automotive airbag cases and meet the following requirements: - 35-85 required rigidity - no cracking and debris when opened - the system is fixed in place when opened - the housing can withstand front impact - service life - can be sprayed for 15 years without affecting function

5) Automobile fuel steam pipe

With excellent drug resistance and low fuel permeability, 1163D and 1172D can be used in fuel steam pipes.

6) Hydraulic hose

In this application, TPEE is mainly used to strengthen the inner layer of the pipe, with excellent oil resistance and a service life of nearly 6 years, while easily meeting the SAE 100R7 standard in 60-80 operating environments.

7) tracheal filling

TPEE's excellent pressure resistance, excellent creep performance, spiral resilience is better than PA11 and TPU, suitable for aeration coils.

8) Air brake tube

Truck air brake pipe, TPEE air brake pipe in accordance with ISO 7628 standard.
