What is ethylene vinyl acetate

Ethylene vinyl acetate (EVA) is a copolymer of ethylene and vinyl acetate. It is a type of thermoplastic thermoplastic known for its flexibility, transparency, and excellent toughness. The ratio of ethylene and vinyl acetate in the copolymer can vary, leading to different properties in the final material.

What is ethylene vinyl acetate

Key features of ethylene vinyl acetate include:

  • Flexibility: EVA is highly flexible, making it suitable for a variety of applications that require a soft and bendable material.

  • Transparency: EVA is generally transparent, allowing for applications where clarity is important.

  • Toughness: It exhibits good toughness and impact resistance, making it durable for many purposes.

  • Chemical Resistance: EVA has resistance to many chemicals, increasing its versatility in a variety of environments.

  • Low Temperature Flexibility: It remains flexible at low temperatures, which is a valuable asset in cold weather conditions.

Due to its combination of properties, EVA is widely used in a variety of industries, including:

  • Shoes: EVA is commonly used in the production of shoe soles and insoles due to its cushioning and shock-absorbing properties.
