The Hardness of EVA Foam Varies According To The Field of Application

What is EVA foam? EVA foam, full name ethylene-vinyl acetate copolymer foam, is a lightweight, soft, good elasticity and thermal insulation performance of the material. It is made of EVA resin and foaming agent through a specific process, and is widely used in many fields such as packaging, construction, sports equipment, etc.

The hardness of EVA foam

The hardness of EVA foam is an important indicator of its softness and hardness, and is usually expressed by Shore hardness. The unit of hardness is degrees (°), and the higher the number, the harder the material. EVA foams are available in a wide range of hardnesses and can be adjusted to meet the needs of different applications.

Highly elastic EVA: With a hardness between 15 and 25 degrees, this material is very soft and has good elasticity. Ordinary EVA: The hardness is about 38 degrees, this material is moderate, and it has a certain hardness and maintains a certain softness.

Medium density EVA: Hardness between 45 and 60 degrees, this material is a bit harder than regular EVA, but still retains good elasticity.

High-density EVA: With a hardness between 65 and 80 degrees, this material is very hard and suitable for applications that require high support.

Application of EVA foam

The application of EVA foam is very wide, and EVA foam of different hardness can meet different functional needs: Footwear manufacturing: EVA foam with low hardness is often used in the sole of sports shoes, providing a comfortable wearing experience and good cushioning performance.

Packaging materials: EVA foam with medium to high hardness can be used as packaging materials to protect electronic products, glass products, etc. from shock and vibration during transportation.

Construction industry: EVA foam is also used in the construction sector, such as floor sound insulation, roof insulation, etc.

Sports equipment: In sports equipment, EVA foam can be used as a cushioning material to reduce the impact during exercise.

Toy manufacturing: Soft EVA foam is suitable for use in children's toys to ensure safety.
