U-Prene® R-1010-2 acts as a powerful performance booster for your existing EVA foam compounds. It is designed to be blended into your current formulations to reach new levels of material excellence.
- Anti-Wrinkle Solution: Significantly smooths the foam surface by reducing shrinkage-induced wrinkles.
- Enhanced Resilience: Boosts rebound energy, transforming "dull" EVA into high-performance bouncy foam.
- Superior Softness Control: Easily lowers hardness to Shore 10C while maintaining excellent structural support[cite: 12].
- Seamless Integration: Drop-in additive that requires zero modifications to existing machinery or processes.
- Improved Dimensional Stability: Controls post-foaming shrinkage for more consistent size and yield[cite: 12, 19, 21].
- REACH (EC/1907/2006) / ROHS (EU/2011/65) [cite: 33]
- California Proposition 65 / PAHs Safety Compliant [cite: 33]

U-Prene® R-1010-2 is a high-efficiency modifier developed to upgrade EVA foaming performance. By simply adding it to existing EVA recipes, you can eliminate defects common in low-hardness foams. It injects superior elasticity and texture into your products without the need for new production equipment.
✅ Smooth Texture, Zero Wrinkles: R-1010-2 provides excellent surface tension control, effectively eliminating shrinkage wrinkles. Even when hardness is reduced to Shore 23C, it maintains exceptional structural integrity.
✅ Ultimate Rebound: Transforming standard EVA into a high-rebound material significantly improves comfort and product longevity.
Flexible Dosage: Recommended starting from 5%, and can be adjusted up to 50% to precisely control the balance between softness and bounce.
