EVA products are widely used in anti-freeze food bags, various secondary membranes, sandwich plates(squeeze membranes), greenhouse membranes and various agricultural production membranes, and high-strength fracture resistant bags. If using EVA products as agricultural film. EVA products have better light transmission, heat preservation, droplet flow, aging resistance, weather resistance and other properties than PE films and PVC double anti-film, EVA products have the advantage of good thermal performance, less heat dissipation at night. It is particularly suitable for cold areas. If EVA products are used as shed membranes, the crop harvest is higher than that of other agricultural membranes, and it is not easy to aging. It can be used continuously for three years. After aging, it is not deformed, it is easy to recycle, and it greatly reduces farmland pollution. Because the copolymers of EVA products are easy to cross-link, and they can be filled with a large number of fillers without brittle cracking, and there is no loss of comprehensive mechanical properties, EVA products are suitable for cable insulation materials for production lines. The most typical applications of EVA products include thermal contractionary insulators, semiconductor insulation materials, and flame retardant insulation materials. Because EVA products have good foaming performance(adding an appropriate amount of foaming agent), EVA products themselves have excellent aging resistance and cracking resistance. At the same time, EVA products have small and uniform bubble holes, so EVA products are widely used in such areas as doormat foam sheets and other foam bodies such as children's wheels, soundproof panels, car parts, slow pedals, gymnastics mats, and yacht protective panels. Can be made into EVA products hot melt glue, widely used in the printing industry wireless binding, packaging cartons, carton seals, label adhesions, furniture corner adhesions and combinations, automotive product assembly, cellulose thin film, polyester thin film, PVC film can be adhesive. Moreover, the adhesive has short curing time, high production efficiency, and is suitable for automated production lines. It does not contain water and solvents, does not need to be dried, does not inflate and deform the adhesive, and has no solvent poisoning and fire problems. It is easy to store and transport. EVA products are completely soluble with asphalt. After modification, they can improve the temperature sensitivity of asphalt(mascara at low temperatures and viscous at high temperatures), rigidity and impact performance. They are widely used in civil engineering, laminate materials, and paving materials.
Trends in EVA materials
The technology development and production of Chinese EVA materials has been more than a decade of history. In the 1980s, Dongguan Chemical Research Institute used high-voltage technology to produce EVA materials above VAIO, and Dongguan Yundong Bubble Cotton Products Co., Ltd. carried out LDPE devices. EVA material development and transformation, It also produced EVA materials for sale on the Chinese market. However, due to reasons such as process equipment and supporting AIDS, large-scale EVA material production has not been formed for many years. China still lacks the capacity to build large-scale advanced EVA material production devices. With the requirements of reform and opening up for commodity diversification and high quality, and the urgent need for EVA materials from all walks of life, China is accelerating the development of EVA materials production. Dongguan Yundong Bubble Cotton Products Co. Ltd. in the LDPE device equipment renovation rehabilitation transformation, while considering the use of foreign advanced technology to improve the EVA material production line. Beijing Organic Chemicals has introduced 40,000 tons of EVA material production equipment and software technology from abroad.
