Si-TPV 2250-75A Eco-Friendly Thermoplastic Elastomer Modifier for EVA Foam
describe:
SILIKE Si-TPV thermoplastic elastomer is a patented dynamic vulcanized thermoplastic silicone-based elastomer which made by a special compatible technology to help silicone rubber dispersed in EVA evenly as a 1~3 micron particles under microscope. Those unique materials combine the strength, toughness and abrasion resistance of any thermoplastic elastomer with desirable properties of silicone: softness, silky feel, UV light and chemicals resistance which can be recycled and reused in traditional manufacturing processes.

Applications
Si-TPV 2250- 75A thermoplastic vulcanizate elastomer is a soft touch, skin-friendly thermoplastic silicone elastomer offering exceptional abrasion resistance, chemical resistance, and excellent adhesion to EVA and other polar substrates
Si-TPV 2250- 75A can be used as an eco-friendly, high-performance thermoplastic elastomer modifier designed for EVA chemical foaming applications. It delivers superior foam quality with uniform cell structure, minimized thermal shrinkage, and enhanced dimensional stability while preventing chemical migration, making it an excellent alternative to supercritical foaming. The material produces ultra-lightweight, soft, elastic foams with exceptional wear/slip resistance and consistent color uniformity, resulting in high product yield. Its excellent processability and cost-efficiency make it ideal for footwear, sports equipment, medical devices, and protective packaging applications, offering both performance and sustainability benefits.
Characteristics
- Improves EVA touch, anti-slip, and color consistency
- Effectively reduces compression set and heat shrinkage.
- Excellent abrasion resistance, stain resistance, and no dust.
- No plasticizers and softening oils, no precipitation.
- Easy to demold, water inlet (flash) is easy to dispose.
