What kind of material does the sole of mountaineering shoe use?
At present, the most commonly used materials for climbing shoes soles can be divided into rubber, EVA, PU, MD and so on.
Rubber (RB): used for all kinds of sports shoes outsole, at the same time, high-grade rubber is also often used as high-grade leather shoes sole material.Advantages: non slip, flexible, easy to break, good softness, good stability, extension and shrinkage, good hardness and good bending.Disadvantages: heavier, Yi Tushuang (is a quality problem), easy to be pierced through; permeability, moisture absorption is not good, afraid of oil immersion, should not be in the gas station and other places to wear oil.
(1) natural rubber: the advantage is that it is very soft, very flexible, applicable to all kinds of sports shoes, but the disadvantage is that it is not wear-resistant. Indoor sports shoes, multi-purpose natural rubber.(2) synthetic rubber: it is divided into wear-resistant rubber, environmental protection rubber, air rubber, viscous rubber, hard rubber, and carbon rubber.
A. wear-resistant rubber: wear-resistant rubber wear resistance and toughness are very good, so very durable, usually in the soles of labor shoes on the use ofB. environmental protection rubber: also known as recycled rubber, this rubber outsole contains up to 10% recycled rubber, the main purpose is to environmental protection.C. air rubber: Rubber contains air, has a certain shock absorption function, but not very wear-resistant, not widely used.D. viscous rubber: viscous rubber is characterized by good flexibility, and is very slippery, generally used in indoor sports shoes.E. 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.F. plus 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.
PU:Polyurethane abbreviation, Chinese name for polyurethane, referred to as polyurethane, polymer polyurethane synthetic materials. With simple modifications, different density, elasticity, rigidity and other physical properties can be obtained. At present, a large number of glass fiber insulation materials, wood, traditional rubber products and so on.Advantages: high hardness, wear resistance, good elasticity, comfortable to wear light; oxidation resistance, flexing resistance, not easy to wrinkle, chemical resistance, excellent damping; skid resistance; good heat resistance; corrosive environment.Disadvantages: strong water absorption, easy yellowing, easy fracture, poor elongation, no water resistance, easy rotting at the bottom, poor ventilation.3.EVA: vinyl acetate copolymer, high polymer material.The utility model has the advantages of portability, good elasticity, good flexibility, uneasy wrinkle, excellent coloring, suitable for various climates, and low cost.Disadvantages: easy to absorb water, easy to dirty, skid resistance is extremely poor, after the soles of the water stained, just like wearing a roller skates.
