The EV-K22CMP Anti-Shrinkage Foaming Agent Masterbatch is a specialized chemical additive designed to address the common industry challenge of high shrinkage rates in EVA (ethylene-vinyl acetate) foam products. This advanced masterbatch is ideal for EVA mold pressing, EVA+PE cross-linked large mold foaming, EVA IP injection foaming, and secondary MD mold pressing processes.


Key Features & Benefits:

✔ Ultra-Low Shrinkage (<0.5%) – Ensures dimensional stability, reducing deformation in finished foam products.
✔ Excellent Whiteness – Enhances the aesthetic quality of foamed goods, making them visually appealing.
✔ Short Molding Cycle – Improves production efficiency by accelerating the foaming process.
✔ One-Pack Solution – Simplifies the mixing process by eliminating the need for additional activators or accelerators.
✔ High Gas Yield (100-105 mL/g) – Provides uniform and consistent foaming performance.
✔ Optimal Decomposition Temp (165-170°C) – Ensures compatibility with standard EVA processing conditions.

Technical Specifications:

  • Chemical Composition: Azodicarbonamide (ADC) & other additives

  • Carrier Resin: EVA

  • Appearance: Yellow granules

  • Recommended Dosage: 5-10%

  • Packaging: 25 kg/bag, stored in a cool, dry place

Applications:

The EV-K22CMP masterbatch is widely used in industries requiring lightweight, durable, and dimensionally stable foam products, including:

  1. Footwear Industry – EVA foam midsoles for sneakers, sports shoes, and sandals with superior cushioning and shape retention.

  2. Sports & Leisure – Yoga mats, gym flooring, and protective gear that demand resilience and low shrinkage.

  3. Packaging Materials – Shock-absorbing foam for electronics and fragile items, ensuring safe transportation.

  4. Automotive Components – Soundproofing pads, sealing strips, and interior padding with long-term durability.
