Polyurethane film-absorbing sole is made of polyurethane resin as the main raw material. Compared with ordinary rubber soles, polyurethane soles have the characteristics of light weight and good wear resistance. Polyurethane soles take polyurethane resin as the main raw material, which solves the problems that domestic plastic soles and recycled rubber soles are easy to break and rubber soles are easy to open.
By adding various additives, the wear resistance, oil resistance, electrical insulation, antistatic and acid and alkali resistance of polyurethane soles have been greatly improved. The author studied and adopted new processing technology, molding technology and appearance design, which made the safety performance of shoes more stable, beautiful, comfortable and durable.
Extended information:
Polyurethane sole is light, with better adhesive rate and comfort than rubber sole and tendon sole. Polyurethane base, good dimensional stability and long storage life; Excellent wear resistance and flex resistance; Excellent shock absorption and anti-skid performance; Good temperature resistance; Good chemical resistance and so on. However, polyurethane bottom can be divided into two types: encrypted polyurethane bottom and foamed polyurethane bottom.
At first, polyurethane soles were only used for shoes in daily life. With the improvement of impact resistance, puncture resistance and skid resistance, they were extended to work shoes and safety shoes. 15% of the safety shoes in the world are made of polyurethane soles.
