TPU Adhesive

Thermoplastic polyurethane resin (TPU) has excellent properties, wide applications, diverse processing methods, and a wide variety of types, 

which can meet various needs. 

TPU is a material with properties between plastic and rubber, with significant performance differences and great development potential.

Its high-strength physical       properties and softness characteristics are flourishing in various industries such as medical, sports equipment, sports shoes, and fashion products.

Polyurethane resin granules are a general term for rubber like elastomers with Urethane (- NHCOO -) groups in their molecular structure, 

which have the following characteristics:

1. Excellent wear resistance and abrasion resistance.

2. Good tensile strength and tear resistance.

3. Good oil and gasoline resistance.

4. Good low-temperature performance/weather resistance/ozone resistance.

5. Comply with the provisions of the Food Hygiene Law.

6. Excellent flexibility and significant noise and vibration reduction effects.

7. Good processability.

Its characteristics:

(1) Renewable processing meets environmental protection requirements/saves costs.

(2) No need for sulfur curing.

(3) Easy to mix and use with other resins.

(4) It can be processed after solvent dissolution.

2 The use of TPU is classified according to the molding method
