Introduction to TPU Raw Materials

TPU (Thermoplastic Polyurethane) is a kind of polymer material that combines the elasticity of rubber and the processing performance of plastics. It is divided into two major types: polyester and polyether. It also has the following characteristics:

• Environmentally friendly and non-toxic: It can be recycled and meets environmental protection standards such as RoHS and REACH in the European Union.

• Excellent elasticity: The elongation at break is as high as 500%-800%, and it is resistant to repeated stretching.

• Abrasion resistance and corrosion resistance: The abrasion resistance is 3-5 times that of natural rubber.

• Wide temperature range adaptability: The operating temperature range is from -40°C to 120°C.

防水透气：微孔结构实现水汽交换，用于户外服装、鞋材；

耐候性强：抗紫外线、耐黄变，延长产品寿命；

粘接性佳：与金属、布料、塑料等基材附着力优异。

Core Advantages of TPU Film: More Than Just a "Film"

Elasticity and flexibility: Suitable for dynamic environments (such as sports equipment, medical devices).

Waterproof and breathable: The microporous structure enables water vapor exchange, and it is used in outdoor clothing and footwear materials.

Strong weather resistance: It is resistant to ultraviolet rays and yellowing, extending the product's lifespan.

Good adhesion: It has excellent adhesion to substrates such as metals, fabrics, and plastics.
