EVA foam is a new type of environmentally friendly plastic packaging material, which may not be well understood by many people. So next, we will introduce what material EVA foam is? What are the advantages?

1、 What material is EVA foam

EVA material is a common term we define, and its full English name is ethylene vinyl acetate copolymer. Its chemical name is ethylene vinyl acetate copolymer, which is an extremely ordinary material and a common type of midsole material in daily life. Products made from it have good flexibility, shock resistance, anti slip, and strong pressure resistance, such as EVA slippers, cotton shoes, EVA phone protective cases, EVAipad protective cases, etc.

2、 What are the advantages of EVA foam

1. Water resistance: Closed cell structure, non absorbent, moisture-proof, with good water resistance.

2. Corrosion resistance: resistant to corrosion from chemicals such as seawater, oil, acid, and alkali, antibacterial, non-toxic, odorless, and pollution-free.

3. Processability: and easy to perform processing such as hot pressing, cutting, gluing, and bonding.

4. Anti vibration: High rebound and tension resistance, strong toughness, and good shock/cushioning performance.

5. Thermal insulation: Excellent insulation, cold resistance, and low temperature performance, resistant to severe cold and exposure to sunlight.

6. Sound insulation: Closed bubble holes, good sound insulation effect.

3、 What are the grades of EVA foam

EVA foam is divided into six levels: C, B, A, A+, 3A, and HR. The hardness of ordinary EVA ranges from 40 to 45 degrees, with a maximum hardness of around 70 degrees. It can be customized according to customer requirements. The two levels of ordinary BC materials are mainly used for lining, various tool box linings, packaging shock-absorbing materials, etc Materials above grade A are made of high elastic foam, mainly used for high-end finished/exported products, with characteristics such as small pores, uniform thickness, environmental protection, and odorless.

4、 What are the uses of EVA foam

1. EVA materials can be used to make household refrigerators, gas pipes, civil construction panels, containers, and other household and daily necessities.

2. EVA materials can be used to make packaging films, gaskets, medical equipment, as well as hot melt adhesives, cable insulation layers, etc.

3. EVA materials are widely used in wireless book binding, digital product shell structural components, furniture edging, assembly of automobiles and household appliances, shoe making, carpet coating, and metal anti-corrosion coating.
