21 kinds of sole materials(2)

7, TPU Sole (cheap shoes, can be used for injection molding base)

The full name of thermoplastic polyurethane elasticity (Thermoplastic Polyurethane), which is a linear polymer material produced by binochenate and macromolecular polyol, and chain expansion agent, is a new type of environmental material.

Advantages: It has excellent mechanical strength, abrasion resistance, oil resistance, and flexion resistance, especially the most prominent abrasion resistance, and the appearance is very generous and high -end.

Disadvantages: heat resistance, heat water resistance, poor compression resistance, easy appearance and yellowing, easy to stick to mold during processing, harder, heavier, poor breathability. However, the contact with the oil will slip.

8. PVC Sole (polyvinyl chloride, commonly known as, plastic bottom)

Polyvinyl chloride, the original color is slightly yellow transparent and shiny. Breakalism will occur at the flexion.

The lower the temperature, the harder the soles of the shoes. On the contrary, the higher the temperature, the softer the sole.

Use direction: Low -grade bottom, injection sole, air cushion shoes, football shoes commonly used materials.

Advantages: light, strong luster. Most cheaper, oil -resistant, wear -resistant, good insulation performance

Disadvantages: Poor non -slip performance, poor texture, cold tolerance, folding, poor breathability.

9.TR Sole (can be used as injection foundation)

TR sole is a new product that improves on TPR. It is a synthetic material for TPE and rubber. The product has more excellent indicator performance; thermal injection plastic processing is formed, and the molecule movement is spherical.

It has the characteristics of many appearance, good feel, bright color, high smoothness, and high technical content, and can be recovered 100%, which is an environmentally friendly sole material.

10. Imitation Leather Sole

It is a typical rubber and plastic and high elastic material. The main ingredients are rubber as the base material, add 10%~ 30%high styrene to imitate the performance of the skin leather.

The appearance is similar to the natural bottom. It has a grain of facial patterns, and its products make lightweight and clear lines; they are brisk and comfortable when they are worn, and there are no sounds, non -slip, and wear -resistant. High hardness and rigidity, its performance is similar to natural leather.

Although it does not have the breathability and moisture absorption of natural leather, it also has the advantages of not afraid of water.

11. BPU

It is a modified new polyurethane (PU), which has the advantages of environmental protection, low density (ultra -light weight), thick surface cord thickness (smooth surface), good toughness, not easy to break, and good resistance. Can replace the EVA bottom, EVA waterproof platform, blowing PVC bottom platform, wooden abycles, PVC foam bottom, etc. This modified polyurethane imitation wood material is very light, with beautiful wood grain, temperature resistance, and adjustable characteristics of the degradation period. It is a new material for green and environmentally friendly.

12. Beef Tendon (Jin) Sole(commonly used)

Thermoplastic Elastomer Bottom, a pale yellow translucent sole, is named after its color and characteristics. "Beef tendon bottom" is as strong as beef tendon, but the bottom of the raw muscles is artificially manufactured, also called thermoplastic elastic rubber bottom. (The first is to start with the rubber beef tendon. The material is connected to the beef tendon color.

Use direction: suitable for tourism shoes and daily life shoes. UGG snow boots brand dedicated bottom.

Advantages: good elasticity, comfortable wear, wear resistance, waterproof.

Disadvantages: slightly poor cold resistance, low temperature will harden, affect the anti -slip effect

The beef tendon can be made with rubber or plastic, and it is most convenient to make with hot plastic rubber (TPR). This sole has a beautiful appearance, and has good elasticity and wear resistance. It is comfortable to wear and walks silent. It is a good soles for tourism shoes and daily life shoes.

Rubber beef tendon: For a long time, there will be a layer of fog secretion on the white surface; cutting a little with a blade with a small amount of fire to ignite a little black and gray, a little white solid, it is difficult to dripping when burning, and a little black smoke with rubber odor. (Now the development of technical development may not appear.)

TPR beef tendon: Use a knife to lit with a little fire. When burning, there are a little gray -green, a dripping phenomenon, a glue odor, and the burning time faster than the rubber beef tendon.

13, Mei Na bottom

Mei Na (also known as Lai Dibu, Rydo, and rubber imitation, etc.), it is actually the rubber bottom, but it is just a different processing method. It is cheaper than the beauty of the beauty,

The texture is fine, wear -resistant, and twisted. It is infinitely extended. Generally, the width is 1 meter. The main component of the rolling beauty bottom is rubber. After the machine comes out, cut into 2 meters long.

It must be rushed with a knife, and then grinds the side color. Generally, the thickness is between 3-5mm, depending on the needs.
