2, PU, no matter from the external thickness, texture, hand, or intrinsic fastness, stretch and toughness, are far superior to PVC.
3, PU and PVC are composed of two parts, consisting of its own ingredients and the base fabric (also known as the base fabric or adhesive). The thickness of the PU itself is generally from 0.5 cm to 1.0 cm, and the thicker the better the quality, the thickness of the base fabric is from 0.5 to 0.8 cm. The base fabric of PU is generally velvet, relatively thick, and the velvet is dense, while the base fabric of PVC is thin and does not say, and it is very sparse, and some are not raised at all.
4, PU is generally divided into three grades of high, medium and low, based on the thickness and texture of the hand, the thicker the better, the more realistic the texture feels better. PVC, slightly better soft, can be used as a fabric, but poor hard PVC can only be used as an auxiliary material.
