Modified EVA Compounds and Colored EVA Compounds expand the application scope of ethylene-vinyl acetate copolymer in two key dimensions: performance and appearance. Through tailored formulation, the modified grade provides enhanced elasticity, thermal stability, and heat shrink performance; the colored grade ensures consistent color delivery and batch uniformity. Both are widely used in footwear, cable, consumer goods, sporting goods, and medical applications, addressing both functional and aesthetic requirements across industries.
EVA compound for slippers is engineered with lightweight softness as the core advantage. The low density ensures each pair stays lightweight without tiring feet; the soft and comfortable texture provides a warm tactile feel. With excellent flow properties, the material enables smooth injection molding and foam expansion, delivering high production efficiency. The finished product offers superior resistance to bending and cracking, making it ideal for household slippers, beach sandals, disposable slippers, and more.
EVA A Grade material for shoe soles features high resilience and durability as its core advantages. The material delivers outstanding rebound performance with comfortable foot feel and clear energy return. Enhanced abrasion and flex resistance significantly extend the service life of shoe soles, preventing cracking and delamination. Ideal for brand footwear, 】and a wide range of sport and casual shoe sole applications.
EVA compound for boots delivers exceptional compressive strength, withstanding sustained pressure and deformation from boot shaft structures. Outstanding abrasion, oil, and hydrolysis resistance ensures reliable performance in harsh environments such as moisture and oil exposure. The finished product maintains a firm and structured shape without collapsing or deforming. Ideal for industrial boots, rain boots, outdoor boots, snow boots, and more.
EVA compound for foam rollers requires superior compression recovery performance with fine and uniform foam structure. The smooth surface delivers a comfortable touch while maintaining long-lasting durability without deformation. The finished product is impact and fatigue resistant, withstanding high-frequency compression and rolling use. Ideal for yoga foam rollers, fitness massage rollers, physiotherapy rollers, and more.
EVA compound for sports equipment accessories requires superior grip feel, shock absorption, and abrasion resistance with long-lasting durability. The surface delivers a comfortable touch with excellent sweat and slip resistance, preventing hardening or cracking even after prolonged use. Hardness can be flexibly adjusted to meet specific accessory requirements. Ideal for golf club grips, tennis racket handles, baseball bat grips, gym equipment handles, and more.
EVA compound for boots delivers exceptional compressive strength, withstanding sustained pressure and deformation from boot shaft structures. Outstanding abrasion, oil, and hydrolysis resistance ensures reliable performance in harsh environments such as moisture and oil exposure. The finished product maintains a firm and structured shape without collapsing or deforming. Ideal for industrial boots, rain boots, outdoor boots, snow boots, and more.
VA (Vinyl Acetate) is the key functional monomer in EVA copolymer, and its content directly governs hardness, flexibility, transparency, and polarity. At 3% VA, the material behaves like LDPE — high hardness, strong abrasion resistance. At 40% VA, it performs like an elastomer — soft, transparent, with excellent low-temperature resistance. This broad performance spectrum means the technical strategy for both color masterbatch and EVA masterbatch must be tailored to VA content.
Low-VA EVA (3%-10%) as a carrier for EVA masterbatch combines the processability of LDPE with moderate polarity, making it the most cost-effective segment for both EVA color masterbatch and EVA modified masterbatch. Practical masterbatch types include black, white, color, flame retardant, UV resistant, antistatic, filler, and EVA-g-MAH grafted masterbatch, widely used in footwear, industrial parts, window seals, electronic cables, and cost-reduced filled products. On the modification side, applications cover foam crosslinked footwear, elastomer-blended flexible hoses, and PA/polyester toughening.
Medium-VA EVA (10%-20%) offers an optimal balance of flexibility and strength, making it the most well-rounded performance range. Practical masterbatch types include black, white, color, flame retardant, UV resistant, high-dispersion masterbatch, and EVA-carrier-specific color masterbatch, widely used in sports shoe midsoles, children’s toys, window and door seals, and cushion packaging. On the modification side, applications cover elastomer-blended foam sheets, crosslinked cushioning materials, and functional filler-reinforced systems. With its balanced polarity, medium-VA serves as the ideal transitional carrier between low-VA and high-VA ranges, offering both processing latitude and performance headroom.
High-VA EVA (20%-40%) features high polarity, softness, and transparency, making it the most technically demanding range. Practical masterbatch types center on EVA-carrier-specific color masterbatch, high-transparency masterbatch, EVA-g-MAH grafted masterbatch, and functional masterbatch, widely used in food packaging film, medical IV tubing, hot melt adhesives, and cable semi-conductive shielding layers.
