What is Thermoplastic Polyurethane (TPU)?

Thermoplastic polyurethane is a type of elastomer that is characterized by its high elasticity, durability, and resistance to abrasion and chemicals. TPU is produced through the reaction of diisocyanates with polyols, resulting in a material that can be processed like plastic but has the flexibility and resilience of rubber.

Key Properties of TPU

• Flexibility: TPU can stretch extensively without breaking, making it ideal for applications requiring flexibility.

• Durability: It exhibits excellent resistance to wear and tear, making it suitable for high-demand environments.

• Chemical Resistance: TPU is resistant to oils, greases, and solvents, which is crucial for many industrial applications.

• Thermal Stability: It maintains its properties over a wide temperature range, making it suitable for various climatic conditions.
