Characteristics and selection of different material sole materials

The characteristics of different material soles are selected. There are many kinds of soles in the market, such as PVC soles, rubber soles, TPR soles, TPU soles, and so on. Many people don't know which material features. Today, we will analyze the characteristics of these four commonly used soles.
TPU sole: TPU is called Thermoplastic Polyurethane in English. It is a polymer material of thermoplastic polyurethane elastomer. It has excellent wear resistance, excellent elasticity, good tear resistance and bending resistance, good oxidation resistance and high hardness. The disadvantage is that the skid resistance is general, not resistant to water and yellowing. TPU sole material is one of the sole materials for special shoes with high requirements, such as football shoes, skates, hiking shoes, etc.
TPR sole: TPR is a thermoplastic rubber, also known as TPE sole. TPR has the properties of rubber and plastic at the same time. It is easy to process and mold, and can be molded after hot melting. TPR soles are easy to form, heavy in weight, moderate in price, but soft and wear resistant. Generally used as the midsole and outsole of casual shoes.
Rubber sole: rubber is called rubber in English, or RB sole for short. Rubber sole can be divided into natural rubber and synthetic rubber. The natural rubber sole has good elasticity and soft feel. Generally, there are many indoor sports shoes, but the disadvantage is that it is not wear-resistant. The soles of synthetic rubber are elastic, wear resistant, anti-skid and flexible, but the soles of other materials are heavy. Most of them are outdoor basketball shoes and sports shoes.
PVC soles: PVC is called Polyvinyl Chloride in English. PVC soles are generally divided into two types. One is injection molded PVC soles, and the other is mold baking molding. In women's shoes, men's shoes are widely used. They are very light to wear, and the soles are soft. Generally, lightweight shoes and household shoes are used.
According to different shoes, choose shoes made of different materials, and the functional benefits will be brought into play.
Recently, I have seen many netizens ask what equipment is used to make soft rubber PVC soles. I also take this article to tell you. Compared with the traditional production equipment, the drip molding sole assembly line is much more efficient, and now it is useful for many local manufacturers.
