[Sell] [Food & Beverage] Ethylene vinyl acetate (EVA) is a versatile thermoplastic copolymer made from ethylene and vinyl acetate that combines the strength of ethylene with the flexibility and elasticity of vinyl acetate. It is used to create a wide range of products, from soft, rubber-like materials and foams to durable plastics, and is known for its flexibility, softness, UV resistance, and low-temperature toughness. By adjusting the proportion of vinyl acetate, the material's properties can be customized, making it suitable for everything from adhesives and sports equipment to medical applications and food packaging.
Properties of EVA
Flexibility and Softness: EVA is an elastomeric polymer that can be made to be very soft and flexible, sometimes described as "rubber-like".
Durability: It has good clarity, gloss, toughness, and resistance to stress-cracking and UV radiation.
Temperature Performance: EVA has good low-temperature toughness and can be formulated with lower heat seal initiation temperatures, notes LyondellBasell.
Processing: It can be processed like other thermoplastics, and its flexibility can be customized for specific applications by adjusting the vinyl acetate content.
Safety: EVA is considered non-toxic and is safe for use in applications such as food packaging, childcare products, and the medical industr
