Ethylene vinyl acetate copolymer (EVA) is a versatile thermoplastic polymer produced from the copolymerization of ethylene and vinyl acetate. Its properties and applications can vary significantly based on the proportion of vinyl acetate, which typically ranges from 10% to 50% by weight.

Key Characteristics

Elasticity and Flexibility: EVA exhibits rubber-like softness and flexibility, making it suitable for applications requiring cushioning and impact resistance.

Chemical Resistance: It is resistant to a variety of chemicals, including alcohols, hydrocarbons, and acids, although it may be unstable in the presence of strong acids and certain solvents.

Durability: EVA is known for its excellent resistance to UV radiation, heat, and aging, contributing to its long-lasting performance in various environments.

Non-Toxicity: The material is considered non-toxic and does not require plasticizers like phthalates, making it a safer alternative to traditional plastics such as PVC.
