Polyurethane base.
Compared with ordinary rubber soles, polyurethane soles are lighter in weight and have better wear resistance. Polyurethane soles use polyurethane resin as the main raw material, which solves the problem that domestic plastic soles and recycled rubber soles are easy to break and the rubber soles are easy to peel off.
By adding various additives, polyurethane soles have been greatly improved in terms of wear resistance, oil resistance, electrical insulation, anti-static and acid and alkali resistance. Using new processing technology, molding technology and appearance design, the safety performance of the shoes is more stable, and the shoes are beautiful, comfortable and durable.
Rubber soles refer to soles made of rubber. Rubber sole materials can be roughly divided into natural rubber or synthetic rubber. The advantage of natural rubber is that it is very soft and has excellent elasticity. It can be suitable for various sports and play a shock-absorbing role. However, its disadvantages are also obvious, that is, it has poor oil resistance, ozone aging resistance and thermal oxygen aging resistance. Indoor sports shoes mostly use natural rubber.
Market Prospects
Polyurethane soles were initially only used for daily wear shoes. With the improvement of impact resistance, anti-perforation and anti-slip properties, they have been extended to work shoes and protective safety shoe. 15% of the world's safety shoes use polyurethane soles. Later, sports shoes and casual shoes were successfully developed. Sports shoes are already high-tech products. Because there are many sports, the requirements for sports shoes are also different.
In order for athletes to give full play to their talents, sports shoes cannot be ignored. Polyurethane soles have a bright future in gymnastics, track and field, and ball games. Polyurethane soles are still being improved, focusing on wet aging, low temperature performance and light stability. In short, microporous polyurethane soles are products with great development prospects.
