What is a PU belt?

PU leather generally refers to polyurethane.

The full name of polyurethane is "superfine fiber reinforced leather", commonly known as "PU leather". It has excellent wear resistance, excellent air permeability, aging resistance, softness and comfort, strong flexibility and environmental protection effect advocated now.

Polyurethane feels as soft as leather. Polyurethane is a newly developed high-grade leather in synthetic leather and belongs to a new leather material. Because of its advantages of wear resistance, cold resistance, air permeability, aging resistance, soft texture, environmental protection and beauty, it has become the best choice to replace natural leather.

Practice has proved that the excellent performance of polyurethane is irreplaceable by natural leather. From the analysis of domestic and foreign markets, polyurethane has also largely replaced natural leather with insufficient resources. As the decoration of luggage, clothing, shoes, vehicles and furniture, polyurethane has been more and more recognized by the market, and its application range, quantity and variety are beyond the satisfaction of traditional natural leather.

Extended data:

Characteristics of PU leather:

1, folding endurance is comparable to natural leather. Bending at room temperature can reach 200,000 times without cracks, and bending at low temperature (-20℃) can reach 30,000 times without cracks (good temperature resistance and mechanical properties).

2. Moderate elongation (good skin feeling).

3. High tear strength and peel strength (high abrasion resistance, tear strength and tensile strength).

4, there will be no pollution from production to use, and the environmental protection performance is superior.

Some top foreign polyurethanes are very high-tech, and high-end applications will be more expensive than leather. The appearance effect of polyurethane is most similar to genuine leather, and its products are superior to natural leather in thickness uniformity, tear strength, bright color and leather utilization rate, which has become the development direction of contemporary synthetic leather.

If the surface of polyurethane is dirty, it can be scrubbed with high-grade gasoline or clean water, and other organic solvents or alkaline substances are not allowed to be scrubbed to prevent the quality from being damaged. Usage conditions of polyurethane: the heat setting temperature should not exceed 25 minutes at 100℃, 100 minutes at 120℃ and 5 minutes at 130℃.
