Classification of polyurethane
- Classification by form
Hard polyurethane: usually used for thermal insulation materials, furniture, etc., with high strength and hardness.
Soft polyurethane: used for synthetic leather, foam mattresses, etc., with good flexibility and comfort.
- Classification by use
Polyurethane coating: used for the protection of wood, metal and other surfaces, with good wear resistance and chemical resistance.
Polyurethane elastomer: used in automobiles, soles, sports equipment, etc., with good elasticity and durability.
Polyurethane foam: used in mattresses, sofas, car seats, etc., to provide comfortable support.
- Classification by chemical composition
Polyether polyurethane: usually has good water resistance and low temperature resistance, and is widely used in various fields.
Polyester polyurethane: usually has higher wear resistance and mechanical strength, suitable for industrial fields.

Pu leather production process
Leather production is divided into two major production processes: dry process and wet process.
Wet process: placing cloth (base cloth) → coating → solidification → washing → drying → winding
Dry process: placing release paper → coating → laminating → drying → peeling and winding

How to care for PU leather
Clean regularly
The frequency of leather maintenance depends on how often you use the product. We usually recommend maintenance every 2 months and deep cleaning with a detergent every six months. This can effectively protect the appearance of the leather and even extend its service life.
Avoid extreme environments
It is not recommended to place any leather product in extreme environments for a long time, whether it is hot sunshine or extremely cold weather and excessive humidity, because high temperature causes the leather oil to evaporate, lose its softness, become dry and brittle, and fade; extremely cold environment causes the leather to lose its elasticity and softness, causing it to crack and damage; humid environment causes the leather to absorb moisture, resulting in the growth of mold or expansion and deformation
Safe storage
When leather products are not in use, we can wrap them in cloth bags or plastic bags and store them in a constant temperature environment. Place insect repellent around them. If it is leather furniture, we can cover it with cloth to avoid bacterial growth. The storage environment should avoid contact with sharp objects to prevent scratches and punctures. In addition, regular inspection and maintenance are required.
