EVA foam

Views: 612 Update date: Jul 23,2018
EVA foam is a new type of environmentally friendly material, belonging to a kind of foam, also known as EVA sponge.


EVA foam can also be produced the color according to customer's requirements. It has A material, B material, C material, low-grade environmental protection material and non-environmental material.




EVA foaming process:
At the decomposition temperature, the foaming agent releases a large amount of gas to form a nucleus. After a sudden pressure relief, the nucleate depressurization causes the EVA and other materials to swell and form a foaming material.


EVA foam foam grade:
Class C, Class B, Class A, Class 3A, CR material, high-elastic EVA material, rubber EVA material, etc. It is often used in the inner lining of tool boxes and packaging boxes, and is also commonly used in environmentally friendly toy craft products.


Advantages of EVA foam:
EVA rubber and plastic products are new environmentally friendly plastic packaging materials with good buffering, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and are non-toxic and non-absorbent. EVA rubber and plastic products are designed and formed, and their shockproof performance is better than traditional packaging materials such as polystyrene (foam), and meets environmental protection requirements. It is the best choice for export products. Compared with shockproof packaging, it can be cut and formed; it can be used for a wider range of applications due to the large difference in density.

Features of EVA foam materials:
a. water resistance: closed cell structure, no water absorption, moisture, water resistance.
b. Corrosion resistance: It is resistant to corrosion by seawater, oil, acid, alkali and other chemicals, antibacterial, non-toxic, odorless and non-polluting.
c. Processability: It is easy to process by hot pressing, cutting, gluing, laminating and so on.
d. anti-vibration: high resilience and tensile strength, strong toughness, good shock/buffering performance.
e. heat preservation: heat insulation, heat preservation, cold resistance and low temperature performance, can withstand severe cold and exposure.
f. sound insulation: closed cells, good sound insulation.


EVA foam application:
Suitable for children's toys, craft gifts, stationery office, mouse pad, sports equipment, decoration, home, travel, packaging, insulation, electrical appliances, toys, electronic products, jewelry, hardware, environmental packaging, cosmetics, composite, auxiliary packaging materials, metal and many other fields.
