What Is TPU (Thermoplastic Polyurethane)?
TPU (Thermoplastic Polyurethane) is a high-performance polymer that combines rubber-like elasticity with the processability of plastics.
It softens when heated and hardens again when cooled, making it suitable for injection molding, extrusion, and thermoforming processes.
What Is TPU Used For?
1. Flexible and Durable Parts
Used to manufacture products that require:
- High elasticity
- Impact resistance
- Excellent abrasion resistance
2. Automotive & Industrial Applications
Applied in:
- Hoses
- Seals and gaskets
- Cable jackets
- Protective coatings
where both flexibility and mechanical strength are required.
3. Footwear & Sporting Goods
Commonly used in:
- Shoe soles and midsoles
- Sports equipment
- Protective components
due to its energy-absorbing and resilient properties.
4. Medical & Food-Contact Grades (Special Grades)
Used in:
- Medical tubing
- Catheters
- Protective films
with appropriate certified grades.
5. Films, Sheets & Coatings
Used to produce:
- Transparent films
- Protective layers
- Shock-absorbing surfaces
Purposes of TPU
- To provide high flexibility and elasticity
- To improve abrasion and tear resistance
- To enhance impact strength
- To ensure chemical and oil resistance
- To produce long-lasting and durable products
Industries That Use TPU
