EVA
Ethylene-Vinyl Acetate (EVA) also known as polyethylene-vinyl-acetate (PEVA), is a copolymer of ethylene and vinyl acetate. In this formation, the weight percentage is variable ranging from 10 to 40 percent and remaining part is ethylene.
There are three different types of EVA copolymer, which differ in the vinyl acetate (VA) content and the way the materials are used.
- • Low proportion of VA (approximately up to 4%)
- • Medium proportion of VA (approximately up to 4%-30%)
- • High Proportion of VA (greater than 40%)
Production
Ethylene-Vinyl Acetate is the thermoplastic resins produced by the co-polymerization process of ethylene and vinyl acetate monomer in a high-pressure reactor.
Advantages
EVA Resin is an elastomeric polymer that produces rubber-like materials that are known for their soft and flexible properties. Other EVA Resin advantages include:
- UV Resistant
- Water Resistant
- Stress-Crack Resistant
- Chemical Resistant
- Excellent Processability & Transparency
Disadvantages
- Difficult to Bond
- Flammable
- Low Strength/Stiffness
- High Thermal Expansion
- Excellent Processability & Transparency
Applications
- Automotive
- Packaging & Paper
- Paints, Coatings & Adhesives
- Electronics & Electrical
- Pharmaceutical
- Footwear
- Photovoltaic Panels
- Others (Agriculture and Medical)
