Silicone Masterbatch Solutions for Footwear & Sports Equipment

If your outsoles are wearing out too fast in DIN or NBS abrasion tests, or your EVA midsoles lose rebound and collapse after a few months of use, the formulation — not the factory — is usually the problem. Xiamen Xiangxi New Material Co., Ltd. develops silicone masterbatch, shoe sole anti-abrasion agents and high-elasticity TPE footwear materials that help footwear compounders pass abrasion and flex tests with a lower loading cost, while keeping foaming uniform and production stable.

Key Challenges in Footwear & Sports Equipment Manufacturing

• Poor outsole abrasion resistance — rubber, TPR and EVA outsoles fail DIN abrasion (mm³) and NBS tests, driving warranty returns and bad reviews.
• Midsole collapse and compression set — EVA foamed midsoles lose cushioning and rebound after repeated impact.
• Uneven foaming cells — coarse or irregular cell structure causes surface defects, low yield and inconsistent density.
• Sticky processing and die build-up — high-viscosity EVA/TPE compounds stick to the die and roll surfaces, forcing frequent cleaning and slowing line speed.
• Compliance pressure — global brands demand RoHS, REACH and FDA-compliant materials free of heavy metals and phthalates.

Recommended Xiangxi Solutions

1. Shoe Sole Anti-Abrasion Agent

Our shoe sole anti-abrasion agent is designed for rubber, TPR and EVA outsole compounds. It forms a self-lubricating siloxane network inside the polymer, reducing surface wear depth noticeably at typical loadings of 1.5–3 phr, without sacrificing bonding with cement or PU adhesive.

2. High-Elasticity TPE Footwear Material

Our independently developed high-elasticity TPE footwear material delivers excellent rebound resilience, low compression set and uniform, fine cell structure for foamed midsoles. It shortens mixing time, blends easily with EVA and TPE substrates, and meets EU RoHS, REACH and FDA requirements — suitable for running, basketball, hiking, work-safety shoes and children's footwear.

3. Silicone Abrasion Masterbatch for EVA / Outsole

Ultra-high molecular weight siloxane dispersed in a compatible carrier improves melt flow and demolding, raises line speed, and reduces die build-up during injection and foaming of outsoles and midsoles.

FAQ — Footwear & Sports Equipment

What dosage of silicone masterbatch should I add to EVA midsole foam?

Typical dosage is 1–3% depending on the hardness and foaming system. Our engineers recommend starting at 1.5% and adjusting against rebound and abrasion targets in your trial.

Will the anti-abrasion agent affect outsole bonding or coloring?

No. The siloxane phase is dispersed at micro level and does not migrate to the surface in amounts that interfere with cementing or masterbatch coloring; bonding strength remains within spec in standard pull-off tests.

Do your footwear materials comply with EU and US brand requirements?

Yes. Products are produced under ISO9001 and designed to meet REACH, RoHS and FDA requirements, with no heavy metals or phthalate plasticizers — suitable for premium sports and children's footwear.
