TPU Outsole Material | High Abrasion & Anti-Yellowing Shoe Sole TPU Resin
TPU Outsole Material
High-abrasion TPU compounds for direct-injected shoe outsoles.
Designed for sports shoes, casual shoes and safety / industrial footwear.
Provides excellent wear resistance, anti-yellowing performance and long service life under daily flexing.

Anti-yellowing
Hydrolysis Resistant
Direct Injection
Shore 85A–98A
Where This TPU Is Used
Outsole TPU is typically used in:
- Sports & running shoes – grip, flexibility, impact resistance
- Casual / fashion shoes – transparent or colored outsoles, anti-yellowing
- Safety / work shoes – high hardness, cut resistance, oil resistance
Compared with rubber or TPR, TPU outsoles can deliver higher abrasion resistance and better long-term mechanical stability, while still allowing direct injection molding and color customization.
Key Advantages of TPU for Outsoles
- High wear resistance – long-lasting outsole even under heavy walking and bending
- Hydrolysis resistance – suitable for hot and humid climates
- Anti-yellowing – keeps clear or light-colored soles looking clean
- Good flexibility at low temperature – outsole does not crack in cold weather
- Ready for direct injection – no vulcanization process required

Typical Grades for TPU Outsoles
| Grade | Hardness | Key Performance | Typical Use |
|---|---|---|---|
| Sole-Tough 90A | 90A (~30D) | High abrasion resistance, hydrolysis resistance | Sports / running shoe outsoles |
| Sole-Tough 95A | 95A (~40D) | High hardness, long service life, anti-yellowing | Casual / fashion shoe soles, colored or transparent soles |
| Work-Sole 40D | ~40D (very firm) | Oil resistance, cut resistance, anti-slip | Safety / industrial footwear outsoles |
Note: The naming above is internal grade naming for reference. Custom hardness and color can be supplied.
Processing & Production Method
These TPU outsole compounds are designed for:
- Direct injection molding into the final outsole shape
- Good flowability for complex tread geometry
- Fast cycle time without vulcanization
Recommended melt temperature: typically 180–210 °C (actual setting depends on mold design and hardness).
