The advantages and characteristics of EVA foam are introduced in detail

 

EVA foam is a new type of environmental protection material, EVA foam is a kind of foam, also called EVA sponge. EVA foam can produce required specifications according to customer needs, and is divided into A material, B material, C material, low-odor environmental protection material and non-environmental protection material.

 

1. The whole process of EVA polyurethane foaming: In EVA polyurethane foaming, the styrofoam releases a lot of gas at the dissolving temperature, resulting in foam core. After the pressure is released suddenly, the pressure of the foam core will cause EVA and other materials to swell. Polyurethane foam material.

 

2. Advantages of EVA foam:

EVA foam is a new type of environmentally friendly plastic packaging material. It has the advantages of excellent buffering, earthquake resistance, heat insulation, waterproof, chemical resistance, etc., and it is non-toxic and non-hygroscopic. EVA foam is produced and processed through a design plan. Its shock resistance is better than traditional packaging materials such as polyethylene (foam), and it complies with environmental protection regulations. It is the best choice for exporting foam. Relative to shock-resistant packaging, it can be laser cut and shaped; because of the large difference in relative density, it can also have more general main uses.

 

3. EVA polyurethane foam grade:

EVA polyurethane foam grades are divided into C grade, B grade, A grade, 2A grade, CR material, elastic foam EVA material, and vulcanized rubber EVA material. It is commonly used in the lining of special tool boxes and packaging boxes, and is also often used in environmental protection toy metal products.

4. Characteristics of EVA foam material:

 • Thermal insulation: excellent thermal insulation, thermal insulation, antifreeze and ultra-low temperature performance, and can withstand cold and exposure.

 • Corrosion resistance: resistance to sea surface, vegetable oil, acid, alkali and other chemical corrosion, antibacterial, non-toxic, odorless, zero pollution.

 • Heat insulation: closed cell, sound insulation and noise reduction effect is very good.

 • Anti-vibration: high resilience and anti-supporting force, strong ductility, and excellent anti-vibration/caching performance.

 • Wear resistance: closed cell structure, non-moisture absorption, waterproof, and excellent moisture resistance.

 • Process performance: It is convenient to carry out production and processing such as pressing, cutting, dispensing, and catering.

 

5. The use of EVA foam:

Suitable for children's toys, craft products, stationery, office, gaming mouse pads, sports equipment, decorative design, home furniture, vacation and tourism, packaging, thermal insulation, household appliances, toys, electronic equipment, accessories, hardware, environmental protection packaging, skin care Products, composites, auxiliary packaging materials, metal materials and many other industries.
