Polyurethanes stand out from the crowd as the ideal material for making soles
1. Polyurethane anti-static safety shoes have soft, warm, oil-resistant, flex-resistant and wear-resistant soles. They are more than 6 times more wear-resistant than rubber. They can be adjusted in a wide range according to the requirements of use. Two-color (double-density) double-layer sole, the bottom is a micro-foamed high wear-resistant work surface, and the inner sole is a comfortable foam that is comfortable to wear.
2, extremely light, the specific gravity is only 0.3~0.8, which is much lighter than the commonly used sole material. It is more suitable for thick-soled shoes that require impact resistance and anti-perforation. 15% of the world's safety protective shoes (labor shoes) use polyurethane (PU) soles. .
3, the mold requirements are lower, the production is convenient to invest and save (the foam pressure is small when foaming, only 0.14~0.2Mpa).
4, the molding method is simple, can produce the soles can also produce even shoes, (PU base and various fabrics with strong adhesion) variety and yield changes flexible, suitable for modern industrial production.
