EVA Masterbatch: Your Solution for Durable and Flexible Plastics

EVA Masterbatch is a specialized additive made primarily from ethylene-vinyl acetate (EVA) polymer combined with color concentrates or pigments, used to enhance the color, flexibility, durability, and other properties of plastic and rubber products. It typically contains 20% to 60% pigment content and is used across various industries including footwear, packaging, automotive, construction, and more. EVA masterbatches provide benefits such as high flexibility, transparency, lightweight, non-toxicity, water resistance, durability, noise reduction, and recyclability. They are often used in applications like EVA foaming products, wood-plastic composites, shoe materials, insulation for wires and cables, and hot melt adhesives. There are different types of EVA masterbatches including color masterbatch, foam masterbatch, flame-retardant masterbatch, functional masterbatch (antibacterial, UV resistant), and more, each tailored to specific performance enhancements.

Key Properties of EVA Masterbatch

• High flexibility and transparency suitable for molding and shaping.

• Lightweight and non-toxic, safe for medical and food-related applications.

• High water resistance, excellent durability, and chemical resistance.

• Noise reduction and low thermal conductivity.

• High friction coefficient for slip resistance.

• Recyclable material supporting sustainability.

The main types of EVA masterbatch and their uses are as follows:

1. Color EVA Masterbatch:

   • Used to impart vibrant colors to EVA-based products while maintaining clarity and flexibility.

   • Common in footwear soles, sports footwear, packaging films, and flexible products where appearance is important.

2. Additive EVA Masterbatch:

   • Contains specific additives such as UV stabilizers, flame retardants, anti-block agents, and slip agents.

   • Used to improve product performance like UV resistance in outdoor use, flame retardancy for safety, and slip resistance.

3. Filler EVA Masterbatch:

   • Blended with minerals like calcium carbonate to improve processing, reduce costs, and maintain physical properties.

   • Used in plastic and rubber products to enhance rigidity or hardness economically.

4. Fragrance EVA Masterbatch:

   • Designed for products that require sensory appeal, like scented footwear, mats, or children’s items.

5. EVA Foam Masterbatch:

   • Contains foaming agents and lubricants to produce soft, elastic foam products.

   • Widely used in shoe materials, packaging, and automotive interiors for cushioning and shock absorption.

6. EVA Flame Retardant Masterbatch:

   • Contains flame retardants to make EVA products meet fire safety requirements.

   • Applied in wires, cables, electronic enclosures, and construction materials for fire resistance.

7. EVA Functional Masterbatch:

   • Includes brightening agents, antibacterial additives, UV resistant, and weather resistant components.

   • Used to improve aesthetics, hygiene, and durability of EVA products, especially for outdoor and medical applications.

8. EVA Cooling Masterbatch:

   • Acts as a flow agent and heat stabilizer to improve processing by enhancing resin fluidity and lowering processing temperatures.

9. EVA Silicone Masterbatch:

   • Contains ultra-high molecular weight siloxane to improve flowability, demolding, surface gloss, and impact strength.

   • Useful in flame-retardant materials and products requiring a silky touch.

Common Applications

• Shoe materials (midsoles, EVA injection granulation)

• Plastic modification for improved flexibility and processing

• Rubber products for enhanced weather resistance and softness

• Wire and cable insulation with flame retardant options

• Hot melt adhesives for quick bonding in packaging and manufacturing

• Wood-plastic composites and decorative panels
