EVA
Ethylene Vinyl Acetate — a versatile thermoplastic copolymer formed through the copolymerization of ethylene and vinyl acetate monomers. Tunable from soft and rubber-like to hard and rigid depending on VA content.
One Polymer. Endless Versatility.
EVA combines flexibility, impact resistance, and UV stability in a single polymer system. By varying vinyl acetate content, properties can be tailored from PE-like rigidity to rubber-like softness.
Flexibility at Low Temp
EVA retains flexibility even at very low temperatures (down to –40°C), making it ideal for cold-chain packaging, winter footwear, and refrigeration applications.
UV & Weather Resistance
Excellent resistance to UV radiation and weathering makes EVA the material of choice for solar cell encapsulation and outdoor applications.
Superior Adhesion
Outstanding adhesion to various substrates including metal, glass, and other polymers. The backbone of hot-melt adhesive formulations worldwide.
Impact Resistance
Excellent shock absorption and impact resistance. Widely used in protective packaging, sports equipment, and cushioning applications.
Optical Clarity
Depending on VA content, EVA can range from transparent to opaque. Low VA grades offer PE-like clarity while high VA grades provide rubber-like properties.
Biocompatibility
EVA is biocompatible and approved for medical and pharmaceutical applications. Used in drug delivery systems, medical devices, and healthcare packaging.
What You Can Make with EVA
Footwear
Shoe soles, midsoles, insoles, and sandals. EVA foam provides excellent cushioning, lightweight comfort, and durability for athletic and casual footwear.
Solar Cell Encapsulation
EVA film encapsulates photovoltaic cells in solar panels, providing electrical insulation, UV protection, and long-term outdoor durability.
Hot-Melt Adhesives
EVA-based hot-melt adhesives for woodworking, packaging, bookbinding, and industrial bonding. Strong adhesion with fast setting times.
Packaging & Films
Stretch wrap, shrink films, agricultural films, and food packaging. Also used in wire and cable insulation and healthcare packaging.
Key Properties
Core specifications for EVA copolymer. Properties vary with vinyl acetate (VA) content. See Technical Data Sheet for full details.
| VA Content | 5 – 40% (by weight) |
| Density | 0.93 – 0.96 g/cm³ |
| Melt Flow Index | 0.5 – 25 g/10min |
| Melting Point | 65 – 110°C |
| Shore Hardness | Shore A 40 – Shore D 50 |
| Elongation at Break | 300 – 800% |
Standard PE Equipment
EVA is processed on conventional polyethylene equipment. Processing temperature depends on VA content and grade.
Store in cool, dry conditions below 40°C. Keep sealed in original packaging, away from direct sunlight. High VA grades may exhibit blocking — store in single layers. Shelf life: 12 months.
