What is TPU?
Thermoplastic Polyurethane (TPU) is a versatile elastomer that combines the durability of rubber with the flexibility and processability of plastics. TPU stands out for its high wear resistance, elasticity, and ability to perform in extreme environmental conditions, making it ideal for a wide range of applications across industries such as automotive, footwear, electronics, and medical devices.
What is TPU made of?
The balance between soft and hard segments allows TPU to exhibit exceptional versatility, from soft, flexible materials to tough, rigid ones. The choice of polyol determines the oil and hydrolysis resistance of TPU, and the choice of isocyanate plays a role on physical properties and color stability.
TPU is a polymer composed of three key building blocks:
- Polyols - soft segments: Provide flexibility and elasticity, can be polyether or polyester.
- Diisocyanates - hard segments: Contribute to strength and durability, can be aromatic or aliphatic.
- Chain extenders: Help control TPU’s properties, such as hardness and toughness.
