Identification Methods Of Shoe Materials

Recognition of PU, PVC, TPR, RUBBER and so on!

PU is the lightest and most wearable. Of course, the price is also the most expensive.PU material. The soles are very well recognized. They are very light in the hands, and the holes on the back of the soles are round.

The sole of PVC material is heavier than TPR, and the sole elasticity of.TPR material is better than that of PVC.

Hold the sole firmly and fall down naturally. If you can play it, it will be 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 is that there is no injection hole, and there is smell when sniffing. If you put it on for a long time, you will also grow something white.

The sole of the TR is very bright. It is harder than the sole TPR sole..TR has more holes than TPR. The injection hole is very special.

RUBBER is the heaviest, PU and EVA the lightest.

PU generally can see holes.

Material: PU is expensive, EVA, TPR is moderate, PVC is the cheapest.

TPR is a molding process, and PVC needs to be processed.

ABS generally high heel shoes are expensive and hard.

At the same time, there are other ways to identify! Generally, synthetic leather, such as PVC and PU leather, other than genuine leather, is collectively referred to as artificial leather or imitation leather.

PVC and PU are all polyvinyl chloride (plastics), but the manufacturing processes of these two products are not the same. In the manufacturing process, the PVC products should be mixed into plastic paste by hot melt, then evenly coated on the T/C knitted fabric substrate according to the required thickness, and then foaming into the foaming furnace, so that the softness will be able to adapt to the production of various products and requirements. Surface treatment (dyeing, embossing, polishing, matting, grinding and raising of hair) is carried out at the same time, mainly according to the specific product requirements.

PU leather is more complex in manufacturing process than PVC leather. Because PU's bottom cloth is a canvas PU material with high tensile strength, besides coating on the top of the base cloth, it can also contain the bottom cloth in the middle, so that it can not see the existence of the cloth.

The physical properties of PU leather are better than those of PVC leather. It has good resistance to twists and turns, good softness, high tensile strength and breathability (PVC no).

The pattern of PVC leather is made by hot pressing with steel pattern roller. The pattern of PU leather is pressed on the surface of semi finished leather with a pattern paper first, and then after cooling, the paper leather is separated and treated by surface treatment.

The price of PU leather is more than one times higher than that of PVC leather, and the price of PU leather with some special requirements is 2 to 3 times higher than that of PVC leather.

The pattern paper needed for general PU leather can be scrapped only 4 to 5 times, and the use cycle of the pattern roller is long, so the cost of PU leather is higher than that of PVC leather.

The scope of application of these two materials is also somewhat different.

In terms of footwear, PVC leather is mostly used in the interior or non weight bearing parts, or in the manufacture of children's shoes; PU leather can be applied to the fabric or weight bearing parts of shoes.

In bags, more PVC leather is applicable.

This is because the goods in the bag are different from the feet in the shoes, which do not emit hot air, and do not bear personal weight.

The difference between PU and PVC is relatively easy. From the side angle, the bottom cloth of PU is much thicker than PVC. There is also a difference in hand feeling. PU feels softer; PVC has a harder handle; it can also be burned with fire, and PU tastes much lighter than PVC.
