Description

RELYONTECH EVA Injection Molding Foam Pellets | Sports Shoe Sole Production Grade
Brand: RELYONTECH
Processing Method: EVA Injection Molding (Injection Crosslinking Foam)
Applications: Sports shoe soles, sports shoe midsoles, casual shoe soles, running shoe soles, training shoe soles, and other footwear sole products
Product Overview
RELYONTECH EVA injection molding foam pellets are specifically engineered for sports shoe sole production via EVA injection molding machines. Made from premium EVA resin as the base material, combined with professional modified formulations and advanced compounding technology, this material delivers outstanding abrasion resistance, shrinkage resistance, resilience, and lightweight performance. With uniform and fine foaming, the finished soles feature excellent dimensional stability and long-term reliable quality, meeting the high performance and appearance standards required for sports shoe soles.
Key Advantages
- Customizable Expansion Ratio: Available in S-type (standard expansion ratio) and L-type (high expansion ratio) to precisely match different mold structures and sole dimension requirements.
- Consistent Quality: Strict control over raw material formulation and production processes ensures batch-to-batch performance consistency, providing reliable long-term supply quality and minimizing production variability for customers.
- Odor-Free: Formulated with an eco-friendly compound system, the finished soles are free from any pungent odor, meeting end consumers' expectations for a healthy and comfortable wearing experience.
- Adjustable Curing Time: The curing (crosslinking) time can be flexibly adjusted to match customers' actual production cycles and process conditions, adapting to different injection molding equipment and production rhythms.
- Custom Colors: Full color range customization is supported. Colors can be precisely matched to customer color cards or samples to meet brand-specific aesthetic requirements.
- Customizable Hardness: The material formulation can be flexibly adjusted based on the functional requirements of different sole parts (midsole, outsole, footbed, etc.), offering a range of hardness options from soft cushioning to supportive rebound.
- Excellent Abrasion Resistance: The material undergoes professional modification treatment, giving the finished soles outstanding abrasion resistance that effectively extends sole service life, meeting the high-frequency wear demands of sports footwear.
- Superior Shrinkage Resistance: Through optimized foaming formulation and cell structure design, gas release is uniform and gradual, producing a fine and dense cell structure. This effectively reduces post-molding shrinkage, enhancing dimensional stability and molding precision while minimizing defects such as deformation and warping caused by shrinkage.
