Which is good, polyurethane or rubber sole?
Polyurethane is a kind of polymer with urethane repeating structure unit, which is reacted with isocyanate and polyol. Compared with ordinary rubber sole, polyurethane sole has the characteristics of light weight and good wear resistance. Polyurethane sole with polyurethane resin as the main raw materials, to solve the current domestic plastic bottom and recycled rubber bottom problems such as easy to break the bottom and bottom rubber easy problem of glue. By adding various additives, the polyurethane soles have greatly improved in wear resistance, oil resistance, electrical insulation, antistatic and acid and alkali resistance. The author studied the new processing technology, forming process and appearance design, and the safety performance of the shoes is more stable. And wear beautiful, comfortable and durable, to the domestic leading level.
The advantage of natural rubber is that it is very soft, elastic, excellent and suitable for all kinds of sports, but the disadvantages are also obvious, that is, it is very hard to wear. Indoor sports shoes, multi-purpose natural rubber.
Synthetic rubber is also divided into wear-resistant rubber, environmental protection rubber, air rubber, viscous rubber, hard rubber, carbon rubber.(1) wear resistant rubber: wear resistance and toughness of wear-resistant rubber are very good, so it is very durable, this kind of rubber material is usually used on the big bottom of tennis shoes.(2) environmental protection rubber: also known as recycled rubber, this rubber outsole contains up to 10% recycled rubber, the main purpose is for environmental protection.(3) air rubber: Rubber contains air, has a certain shock absorption function, but not very wear-resistant, not widely used.(4) viscous rubber: sticky rubber is characterized by good flexibility, and very slippery, generally used in indoor sports shoes.(5) hard rubber: hard rubber is the most comprehensive rubber in the outsole rubber. It is tough, slippery and very wear-resistant. It is also widely used. Multifunctional shoes and basketball shoes are mostly made of this kind of rubber.(6) adding carbon rubber: adding the carbon in the ordinary rubber material, the rubber is more durable, mostly using the rubber shoes, and will leave a BRS letter in front part of shoes soles, to use carbon rubber outsole.
