Types of semi-PU leather mainly include the following:
PU on the surface, PVC foam layer underneath: This type of semi-PU leather has a polyurethane (PU) material on the surface and a polyvinyl chloride (PVC) foam layer underneath. This structure makes semi-PU leather have both the softness of PU and the characteristics of PVC foam layer.
Calendered PVC and release-coated PVC: From the manufacturing process, semi-PU can be calendered PVC or release-coated PVC. The production process of calendered PVC is relatively simple and recyclable, so it is low in price and widely used; while release-coated PVC is relatively complex, the production process is relatively complex, and the price is higher.
