Introduce Some Methods And Characteristics Of Shoe Sole Recognition.

About PU, TPR, PVC, RUBBER and other identification methods. It can be distinguished from the following aspects.

1. PU It is the lightest and the most wearable. Of course, the price is the most expensive. The sole of PU material is very good. It is very light in the hand, and the holes on the back of the sole are round.

2. TPR material. shoes The bottom elasticity is better than PVC, holding the sole firmly, naturally falling down, if it can be sprang up, it is TPR.

3, PVC Material Science The sole is heavier than 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. The sole of PVC material is characterized by no injection holes and smelling with the nose. If the storage time is long, the white stuff will grow.

4. TR's sole surface is very bright. It is harder than the sole TPR soles. The injection hole of TR is more than that of TPR, and the injection hole is very special.

5, weight: RUBBER (rubber) is the heaviest, PU and EVA the lightest.

6, materials: PU is expensive, EVA and TPR are moderate, PVC is the cheapest.

7, craft: TPR is formed and PVC is processed, ABS is generally high heel shoe material, expensive and hard.

8, application: PVC is mostly used in parts or non weight bearing parts, or manufacturing. Children's shoes The PU leather can be applied to the fabric or weight bearing part 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 heat or bear human weight.

The difference between PU and PVC is that the difference between the two materials is relatively easy, and the bottom cloth of PU is much thicker than PVC. There are also differences in hand feeling. PU feels soft, PVC feels harder, and can be burned with fire. PU tastes much lighter than PVC.
