After the EVA product is foamed, the EVA product has good heat insulation performance. Because EVA products have good thermal insulation properties, it also means that they will have very good thermal insulation properties. In short, it can resist both severe cold and high temperature.
EVA products have good processing properties. When it is processed, it can be laminated or cut. Because it is very easy to process, there are a variety of EVA products on the market. In addition, the product is very good in water resistance. Putting this material in the water will not have any effect on the product, just take the product out and use it.
EVA products are relatively less harmful to the environment. With the rise of social patterns, people's awareness of environmental protection and the rise of EVA products in the packaging industry play a very critical role. EVA products and materials will be everywhere in people's lives in the future.
1. The elasticity of EVA products is no different from the elasticity of rubber. EVA products are very soft and flexible.
2. It can still have good flexibility, transparency and good gloss at minus 50°C.
3. Excellent chemical stability, good anti-aging and ozone resistance.
Application of EVA products
EVA products are widely used in landlord video bags, various stretch films, sandwich panel extrusion dies, greenhouse films and various agricultural production films, high-strength rupture-resistant bags. If EVA products are used as agricultural films. The light transmission, heat preservation, dripping, aging resistance, weather resistance and other properties of EVA products are better than PE film and PVC film.
The advantages of EVA products are good heat preservation performance and low heat dissipation at night. They are especially suitable for cold areas. If EVA products are used as shed film, the crop yield will increase by more than 10% compared with other agricultural films, and it is not easy to age. It can be used continuously for three years. It is not deformed after aging, is easy to recycle, and greatly reduces the pollution of farmland.
Because the copolymer of EVA products is easy to crosslink, and can be filled with a large amount of fillers without brittleness, and there is no loss of comprehensive mechanical properties, EVA products are suitable for the production of cable insulation materials. The copolymer of EVA products is easy to crosslink, and can be filled with a large amount of fillers without brittleness, and there is no loss of comprehensive mechanical properties, so EVA products are suitable for the production of cable insulation materials.
Typical application areas of EVA products include heat-shrinkable insulators, semiconductor insulating materials and flame-retardant insulating materials, because EVA products have good foaming properties, and EVA products themselves have excellent resilience, aging and cracking resistance. At the same time, EVA products have small and uniform cells, so EVA products are widely used in foam sheets for insoles and other foams such as children's wheels, sound insulation boards, auto parts, pedals, gymnastics mats, yacht protection boards, etc.
EVA products are made into hot melt adhesives, which are widely used in wireless binding, packaging cartons, carton sealing, label bonding, furniture corner bonding and combination in the printing industry, and the assembly of automotive products for cellulose film, polyester film, and poly Vinyl chloride film, etc. can be bonded. In addition, the adhesive has short curing time and high production efficiency. It is suitable for automated production lines. It does not contain water and solvents, does not need to be dried, does not cause the adherend to swell and deform, and has no solvent poisoning and fire problems, and is convenient for storage and transportation. EVA products are completely compatible with asphalt. After modification, it can improve the temperature sensitivity, rigidity and impact performance of asphalt. It has a wide range of applications in civil engineering, layer top materials, auxiliary road materials and other fields.
