Now people's living standards have been greatly improved. No one makes their own shoes and wears them. Everyone is a finished shoe on the Guomai market. Not only beautiful, but also very affordable. Whether the shoes are comfortable to wear has a lot to do with the material of the sole. So what is the material of the sole material now? Which kind of sole is better? What kind of sole can play a good anti-slip effect?
1. What are the materials of the sole
1. The combination of sole components RB, EVA, TPU, air cushion and pillar
RB+EVA=MD, RB+EVA+air cushion, RB+EVA+post, RB+EVA+TPU, RB+EVA+TPU+air cushion, RB+EVA+TPU+post.
2. MD, EVA
MD: The collective term for MOULD or PHYLON. Correction: MD is the abbreviation of MOULDED, which means EVA composite rubber outsole molded by mold.
PHYLON: (commonly known as Feilong) is a material for shoe soles, a midsole used in general shoemaking. It is a mixture of EVA foam that is heated and compressed. (It is an EVA secondary high-pressure molded product) features light weight, elasticity and shock resistance The performance is good, and the hardness is controlled by the foaming temperature.
EVA: Ethylene Vinyl Acetate-ethylene resin acetate fiber. Shoe door crooked supplement, English full name Copolymer of ethylene vinyl acetate in Chinese, "Ethylene Vinyl Acetate" is a light and elastic chemical synthetic substance.
Therefore: MD soles must contain EVA, MD soles are also called PHYLON soles.
For example, MD=EVA+RB or EVA+RB+TPR and some shoes are RB+PU, etc.
3. RB, PU, PVC, TPU, TPR, TR
RB: RB is the abbreviation of rubber (rubber) in English; rubber includes natural rubber and synthetic rubber (see Appendix 1 for specific instructions). Rubber: used for outsoles of various sports shoes.
PU: Polyurethane, a high-density and durable material based on foam rubber that is often used in the midsole of the back palm.
PVC: polyvinyl Chloride, the natural color is yellowish translucent, shiny. Whitening will appear at the inflection.
TPU: The full name is Thermoplastic Polyurethane, which is a linear polymer material produced by the joint reaction of diisocyanate, macromolecular polyol, and chain extender.
TPR: Thermoplastic Rubber (Thermoplastic Rubber), is a material that has the characteristics of rubber and thermoplastics. It has the properties of rubber and can be processed and recycled as thermoplastics. It can be injection molding, extrusion molding, Rubber products are made by blow molding.
TR: The synthetic material of TPE and rubber has the characteristics of many patterns, good hand feeling, bright color, high smoothness, high technical content, etc., and it can be 100% recycled. It is an environmentally friendly sole material.
Second, what material is good for the sole
PU is the lightest and most wear-resistant. Of course, the price is also the most expensive.
The sole of the PU material is easy to recognize, it is very light in the hand, and the holes on the back of the sole are round.
The sole of the PVC material is heavier in the hand than the TPR.
The elasticity of the sole of TPR material is better than that of PVC. Hold the sole firmly and fall naturally. If it can bounce, it is TPR.
The sole of PVC material is cheaper than TPR, but the quality is not good, especially in winter, it is easy to break the bottom.
One characteristic of the PVC sole is that there is no injection hole, and if you smell it with your nose, it will have a smell. If it is left for a long time, it will grow white.
The surface of the TR sole is very bright. It is harder than the general TPR sole. TR has more injection holes than TPR. The injection holes are very special.
Weight: RUBBER (rubber) is the heaviest, PU and EVA are the lightest
Material: PU is expensive, EVA, TPR is moderate, PVC is the cheapest
Process: TPR is a molded product, while PVC needs to be processed. ABS is generally a material for
high heels, which is expensive and hard.
Application: PVC is mostly used in linings or non-weight bearing parts, or to make children's shoes; PU leather can be applied to footwear fabrics or weight bearing parts. In terms of bags, PVC leather is more suitable. This is because the items in the bag are different from the feet worn in the shoes and will not emit heat; there is no need to bear personal weight.
The difference between PU and PVC is relatively easy. From the corners, the PU base fabric is much thicker than PVC, and the feel is different. PU has a softer feel; PVC has a harder feel; it can also be burned with fire. PU The smell is much lighter than that of PVC.
3. What kind of shoe sole is non-slip
1. RB bottom, commonly known as: rubber bottom, good wear resistance, but heavy.
2. The TPR bottom is light, but it is not wear-resistant and environmentally friendly.
3. PR bottom, commonly known as: polyurethane bottom, light weight, but not wear-resistant, can be automatically decomposed, very environmentally friendly.
4. MD bottom, commonly known as: Huailong outsole, the bottom is a rubber sheet, and the upper layer is high-elastic EVA, which is non-slip and light. At present, first-class brands at home and abroad use this substrate.
5. PVC bottom, commonly known as: plastic bottom, non-wearing, mainly used for low-end shoes.
So there are only two kinds of best for non-slip bottom!
One is RB rubber sole, all rubber material, mainly used for skateboarding shoes,
Casual Shoes.
One is MD Huailong sole, the bottom is rubber, mainly used for hiking shoes, running shoes.
This article details the sole materials of shoes currently on the market. Through the introduction, we can know that there is a big difference in the material of the sole of the shoe. Of course, the price of the better sole will be more expensive. The non-slip soles are rb rubber sole and md Huailong sole.
