EVA shoe material, EVA is abbreviated as EVA by ethylene-vinyl acetate polymer.
PHYLON material belongs to secondary foam midsole. Plastic particles are heated and foamed twice, then poured into a mold and cooled under pressure. In the foaming process, the density change of the material can be controlled by setting the temperature.
2. Different characteristics
EVA is easy to deform, yellow and shrink after a long time, and at the same time, it improves flexibility, impact resistance, filler compatibility and heat sealing performance.
PHYLON is light, elastic, delicate in appearance and not easy to degrade, which is not conducive to environmental protection.
Extended data
1, EVA midsole refers to the shoe midsole that is molded once after EVA is injected into the mold and heated at high temperature. It is also called foam midsole.
EVA particles are directly injected into the mold of the machine by hot-pressing EVA injection machine. After vacuum vulcanization for about 400 seconds, the mold is opened, and the soles in the mold are foamed and shaped, and then shaped by a hot and cold shaping box.
The word 2.Phylon originated in America. In the past, the midsole of all sports shoes was called Phylon. Later, with the continuous development of footwear products, some large footwear products factories distinguished the name of midsole according to the manufacturing process. As a patented technology of Nike.
