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 made of PVC is heavier in the hand than TPR.
The elasticity of the sole of TPR material is better than that of PVC. Hold the sole firmly, and it will fall down 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 of the characteristics of the sole of PVC material is that there is no injection hole, and if you smell it with your nose, it will have a smell. If you leave it for a long time, it will grow white things.
The surface of the sole of TR is very bright. It is harder than the general TPR sole. The injection hole of TR is more than that of TPR. The injection hole is very special.
In terms of weight: RUBBER (rubber) is the heaviest, PU and EVA are the lightest
Material: PU is expensive, EVA, TPR are moderate, PVC is the cheapest
In terms of technology: TPR is a molding, while PVC needs to be processed. ABS is generally the material of high heels, which is expensive and hard.
Application: PVC is mostly used in lining or non-weight-bearing parts, or in the manufacture of 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 item in the bag, unlike the foot in the shoe, does not emit heat; it does not bear the weight of the individual.
The difference between PU and PVC is relatively easy. From the corners, the base fabric of PU is much thicker than that of PVC, and the hand feel is also different. PU has a softer hand; PVC has a harder hand; it can also be burned with fire. The taste is much lighter than that of PVC.
