1, with excellent wear resistance, excellent air permeability and aging resistance. The folding fastness is comparable to that of 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). High tear strength and peel strength (high abrasion resistance, tear strength and tensile strength).
3. It belongs to regenerated leather, which is softer and more flexible than real leather. It is a high-grade leather in synthetic leather and belongs to a new leather material.
4, there will be no pollution from production to use, and the environmental protection performance is superior.
5. It has the advantages of wear resistance, cold resistance, air permeability, aging resistance and beauty, and is the best choice to replace natural leather.
Extended data
PU coating on fabric surface first appeared in the market in 1950s. By 1964, DuPont Company of the United States had developed a PU synthetic leather used as an upper.
After years of continuous research and development, PU synthetic leather has been rapidly improved in product quality, variety and output. Its performance is getting closer and closer to that of natural leather, and some of its performance even exceeds that of natural leather, reaching the point where it is inseparable from natural leather, and occupies a very important position in human daily life.
Microfiber synthetic leather is superior to natural leather in chemical resistance, quality uniformity, large-scale production and processing adaptability, waterproof and mildew resistance. Practice has proved that the excellent performance of synthetic leather is irreplaceable by natural leather. From the market analysis at home and abroad, synthetic leather has largely replaced natural leather with insufficient resources.
