Deskripsyon
Ethylene-vinyl acetate (EVA) foam is a versatile, closed-cell, thermoplastic polymer material known for being lightweight, durable, and highly cushioning. It is frequently used in footwear (midsoles), sports padding, protective gear, yoga mats, and cosplay costumes due to its shock absorption and moldability.
What is EVA Foam
- Composition: It is a copolymer of ethylene and vinyl acetate.
- Properties: It is flexible, buoyant, waterproof, and resistant to UV radiation and chemicals.
- Structure: As a closed-cell foam, it is impermeable to liquids, making it ideal for sealing applications.
- Characteristics: It can be formulated in different hardness levels and is known for its ability to be heat-shaped, retaining its form after cooling.
Key Applications
- Footwear: Used for midsoles, insoles, and outsoles, offering high comfort and impact resistance.
- Sports Equipment: Employed in helmets, bicycle saddles, fishing rod grips, and gym mats.
- Protective Padding: Used for knee pads, elbow pads, and within automotive interiors for vibration dampening.
- Crafting & Cosplay: Widely used by hobbyists for armor, props, and costumes due to its ease of cutting and heat shaping.
- Industrial & Packing: Utilized for gaskets, sealings, and protective packaging, as well as in construction for flooring and insulation.
- Marine Industry: Often used in boat fenders and decking.
