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.

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.
EVA Masterbatch is commonly classified by Melt Flow Index (MFI), one of the most important parameters for selecting the right grade. High MFI masterbatches flow quickly, enabling faster production cycles and better dispersion, making them ideal for film blowing, injection molding and high-concentration colorants. Low MFI masterbatches offer higher mechanical strength and melt strength, suiting extrusion, pipe, sheet and foaming applications. Each class requires specific carrier matching, addition levels and dispersion strategies.
High MFI EVA Masterbatch flows quickly and disperses pigments evenly, making it the preferred choice for three key applications. In film blowing and casting, it produces thin, uniform films with smooth, glossy surfaces. In injection molding, it fills thin-wall and small precision parts fast, minimizing flash and shortening cycle times. In color concentrates themselves, a high-flow carrier with high pigment loading ensures outstanding dispersion. For best results, the carrier’s Melt Flow Index should be equal to or higher than the base resin, addition levels typically range from 1% to 3%, and transparent or high-gloss colors show the most obvious effect.
Low MFI EVA Masterbatch provides higher mechanical strength, toughness and melt strength, making it the preferred choice for demanding applications. In extrusion, it ensures stable, continuous production of sheets, pipes and profiles with excellent dimensional accuracy. In compression molding, high melt strength prevents large and foamed sheets from collapsing. In foaming, slow bubble growth creates uniform cells with a controllable expansion ratio. However, the high viscosity of low MFI base resins makes pigment dispersion more difficult. Practical solutions include using a high MFI carrier or pre-dispersed masterbatch, raising addition levels to 2%–4% (higher for dark colors)
Functional EVA Masterbatch goes beyond simple coloring by adding specialized additives that solve real performance challenges. For everyday products, color masterbatch delivers reliable black, white and full-color grades. UV resistant grades protect outdoor items from yellowing; halogen-free flame retardant grades help cables and electronics meet UL94 V-0; foaming masterbatches support shoe midsoles and mats; antistatic and conductive grades protect electronics packaging; antibacterial grades keep medical and daily products hygienic. For the most demanding uses, medical grade masterbatch meets USP Class VI and ISO 10993 biocompatibility, while toy grade masterbatch complies with EN 71-3 safety limits.
EVA Color Masterbatch provides black, white and full-color grades for all EVA products — footwear, film and toys — with high dispersion, no color specks and no migration as the basic quality threshold.
UV Resistant EVA Masterbatch combines UV absorbers and HALS light stabilizers with pigments to prevent yellowing and aging, extending the service life of outdoor footwear, cables and toys under prolonged sunlight.
Flame Retardant EVA Color Masterbatch uses halogen-free additives such as ATH and MDH to help EVA compounds reach UL94 V-0, making it the right choice for cables, electronics housings and building materials with RoHS-compliant export requirements.
