How Many Kinds Of Shoes And Soles Are There?

"P > RB" is the abbreviation of English Rubber (rubber); hot plastic molding, natural rubber and regenerated rubber.

It is heavy and oil resistant. When molding the bottom, it must be rough on the bonding surface. It is easy to shorten when heated, and the color is not consistent.

Advantages: good abrasion resistance, skid resistance, elasticity, no breakage, good softness, good elongation, stable shrinkage, good hardness, good bending property and waterproof.

Disadvantages: heavier, Yi Tushuang (quality problems), not easy to corrosion (environmental problems); not hard, easy to be penetrated; permeability, hygroscopicity is not good, afraid of oil immersion, should not be worn at the gas station and other oil contacts.

The rubber foaming weight is lighter than that of the rubber bottom, and has rubber smell. When the finger is on time, the surface rebound is more obvious than that of the general < a target= "_blank" href= "http://www.91se91.com/" > the shoe < /a > the wear resistance is poor.

High pressure polyethylene rubber sole is made of high pressure polyethylene and rubber flavored soles, rubber and plastic.

< p > polyurethane is the abbreviation of polyurethane, the English name is polyurethane, it is a kind of polymer material, it is made of A/B/C polyester material, and it is divided into two kinds: oil and water.

It is a new organic polymer material. It is known as "the fifth largest plastic" and is used to produce high-grade leather shoes, sports shoes and travel shoes.

Advantages: low density, soft texture, good elasticity, comfortable and light wearing, good oxidation resistance, excellent abrasion resistance, flexural resistance, high hardness, excellent shock absorption and skid resistance, better temperature resistance, good chemical resistance, easy corrosion, and easy to wrinkle.

Disadvantages: strong water absorption, yellowing, easy to break, poor elongation, water resistance, bottom perishability and poor ventilation.

< p > Ethylene Vinyl Acetate- vinyl acetate copolymer, polymer material.

It is commonly used in jogging, slow walking, casual shoes and midsole training.

Light weight, easy to process, no wear resistance, no oil resistance.

Advantages: light weight, good elasticity, flexibility, wrinkle free, excellent coloring and suitable for all kinds of climates.

Disadvantages: easy to absorb water, not easy to corrode, environmentally friendly and easy to dirty.

The general name of "P > MODEL or PHYLON dragon is EVA's two high-pressure molding product.

MD soles must contain EVA, and the bottom of MD is also called PHYLON bottom.

For example, MD=EVA+RB or EVA+RB+TPR, and some shoes are RB+PU and so on.

Advantages: lightweight, elastic, fine appearance, soft degree, easy to clean, hardness, density, tensile force, tear and elongation.

Disadvantages: it is not easy to corrode and is unfavorable to environment protection. It is easy to wrinkle and shrink easily at high temperature, and its durability is poor.

< p > TPR was originally a generalized term, including TPV, SEBS, SBS, TPO, TPU, EVA and other products.

TPR soles are commonly referred to as SBS modified shoe materials (belonging to the application of TPR materials).

TPR shoe special material is a new type of polymer shoe material which is mainly produced by thermoplastic SBS. The properties of rubber can also be processed and recycled according to thermoplastic plastics. It can be made of rubber molding products by means of injection molding, extrusion molding and blow molding.

When the TPR pellets are melted and molded, the molecules move in the form of emissivity.

Advantages: easy to shape, cheap, light, comfortable, high elasticity, easy to stain, breathable, high strength, especially low temperature resistance, high friction coefficient, strong grip.

Disadvantages: heavy material, poor wear (non abrasion), poor flexibility, poor bending resistance, poor shock absorption and poor ventilation.

< p > total Thermoplastic thermoplastic polyurethane elastomer (Polyurethane), which is a linear polymer material produced by reaction of diisocyanate and macromolecular polyols and chain extender, is a new environmental protection material.

Advantages: excellent mechanical strength, wear resistance, oil resistance and flexural resistance, especially wear resistance is the most outstanding, good appearance, generous high-end.

Disadvantages: heat resistance, hot water resistance, compression resistance is poor, the appearance of yellow, easy to mold in processing, hard, heavy, poor ventilation.

< /p >

< p > PVC polyvinyl Chloride, its natural color is yellow, plucent and glossy.

Albinism occurs at inflection points.

Advantages: most are cheaper, oil resistant, wear-resistant and good insulation.

Disadvantages: poor skid resistance, poor texture, no cold resistance, no folding resistance and poor ventilation.

< p > TR < a href= "http://sjfzxm.com/news/index_x.asp" > shoe sole material < /a > is a new product modified on TPR basis. It is a synthetic material of TPE and rubber, and the product has better performance of various indicators. When hot injection molding is processed, the molecules are pported by rolling ball.

The utility model has the characteristics of many outward appearance, good handle, bright color, high smoothness and high technical content, and can be recycled by 100%, which belongs to the environmentally-friendly sole material.

< p > is a typical rubber and plastic material with high elasticity. The main component is rubber, and 10% to 30% high styrene is added to imitate the properties of leather.

Its appearance is similar to that of natural leather. It has a grain pattern. Its products are light and clear, and it is light and comfortable when worn. It has no noise, no slip and wear resistance. This sole has good elasticity and high hardness and rigidity. Its properties are similar to natural < a target= "_blank" href= "http://www.91se91.com/" > leather < /a >.

Although it does not possess the breathability and moisture absorption properties of natural leather, it also has the advantage of not being afraid of water.
