Below are some normal raw materials needed in PU synthetic leather production (for reference):
- Polyurethane resins: PU synthetic leather is made by coating a fabric substrate with a layer of polyurethane resin. The polyurethane resin provides the material with its durability, flexibility, and water-resistant properties.
- Backing material: The substrate, or backing material, used in the production of PU synthetic leather can be made from a variety of materials including polyester, nylon, cotton, or a blend of these materials. The backing material provides the structure and strength of the material.
- Solvents and additives: During the production process, solvents and additives may be added to the polyurethane resin to improve its properties. These can include plasticizers, cross-linking agents, and pigments.
- Release paper: Release paper is used to prevent the PU synthetic leather from sticking to itself during the production process. The release paper is removed once the material is finished.
The specific raw materials used in the production of PU synthetic leather may vary depending on the desired properties and intended use of the material. For example, materials used in the production of automotive upholstery may be different than those used for footwear or fashion accessories.
