TPEE (thermoplastic polyester elastomer) is a material between rubber and plastic that has both the processing properties of

 plastic and the physical properties of rubber. The following are the advantages and disadvantages of TPEE materials:

Advantages:

Elasticity: TPEE has good elasticity, can be restored after stretching, and this recovery ability is durable.

Chemical resistance: TPEE generally has good resistance to oils, fats and many solvents.

Heat resistance: Compared to most other thermoplastic elastomers (TPEs), TPEE can withstand a higher temperature range, 

which is better in heat resistance such as TPU plastics.

Processability: TPEE can be molded by conventional thermoplastic processing methods (such as injection molding, extrusion, etc.).

Weather resistance: TPEE material is resistant to UV and ozone aging, suitable for outdoor applications.

Strength and toughness: Good physical and mechanical properties, including high strength, high elongation at break and 

excellent tear resistance.

Reuse and recycling: TPEE is thermoplastic, which means it can be heated into shape and recycled at the end of life.

Cons:

Cost: Compared to some other types of TPE or general purpose thermoplastics, the price of TPEE may be higher.

Friction resistance: Although TPEE has good wear resistance in most cases, it may not be as good as some specific materials, 

such as high-performance thermoplastic polyurethane (TPU).

Adhesibility: TPEE may not be easily bonded to other materials and may require special surface treatment or bonding techniques.

Elasticity: For some applications, although TPEE is elastic, it may not be as elastic as natural rubber or other specific synthetic rubber.

Hardness range Limitation: TPEE provides a certain hardness range, but may not provide the minimum hardness values required 

for some applications.

Each material is selected based on its performance in a specific application, and TPEE materials, due to their unique properties

and advantages, make them particularly prominent in applications requiring high strength, high heat resistance and good elasticity, 

such as automotive parts, power cables, sporting goods and some consumer electronics components are widely used.
