Complete Guide on TPU (Thermoplastic Polyurethane): Types, Applications, Properties, Recycling & More

1. What is TPU? | Full Form and Definition

TPU stands for Thermoplastic Polyurethane.
It is a highly versatile elastomer that combines the properties of rubber and plastic. Known for its flexibility, toughness, and resistance to abrasion, TPU is widely used in industries ranging from footwear to automotive.

Highlights:

• Flexible like rubber, processable like plastic

• High elasticity, durability, and transparency

• Resistant to oils, greases, and abrasions

2. TPU Category, Types, and Grades

Types of TPU:

• Polyether-based TPU: Good hydrolysis resistance, ideal for medical & outdoor use

• Polyester-based TPU: High mechanical properties, commonly used in footwear, films

• Polycaprolactone-based TPU: Improved flexibility and low-temperature performance

Grades:

• Injection molding grade

• Extrusion grade

• Medical grade

• Flame-retardant grade

• Anti-static TPU

3. TPU Uses, Applications, and Products

TPU is used in applications requiring flexibility, strength, and durability.

Common Applications Include:

• Footwear: Soles, insoles, sports shoes

• Automotive: Interior trims, hoses, gaskets
