With the development of science and technology and the concept of environmental protection, many new materials have emerged on the market, among which water-based PU leather and oil-based PU leather are two common materials.
They have their own characteristics in terms of performance, environmental protection, etc., and today we will learn about the characteristics of these two materials and the differences between them.
Water-based PU leather
Water-based PU leather is a polyurethane synthetic leather with water as a solvent, which is environmentally friendly, non-toxic and harmless. In the production process, it uses water as a dispersion medium and does not contain harmful solvents, so it has a low environmental impact. In addition, water-based PU leather has good breathability and moisture absorption, making it more comfortable to wear.
Oily PU leather
Oily PU leather is a polyurethane synthetic leather with organic solvent as the medium, and its production process is relatively mature and the cost is low. Oily PU leather has good toughness and elasticity, and can resist external impact to a certain extent.
In addition, oil-based PU leather also has good scratch resistance and chemical corrosion resistance, and is suitable for some occasions with high requirements for material performance. However, oily PU leather will produce certain pollution in the production process and cause certain pressure on the environment.
The difference between water-based PU leather and oil-based PU leather
1.Environmental protection: water-based PU leather is made of all-water-based materials and water-based technology in the production process, and does not contain harmful substances, such as DMF (N, N-dimethylformamide), heavy metals, etc., so it has good environmental protection performance and is more friendly to the human body and the environment; However, oily PU leather uses more organic solvents in the production process, and the volatilization cycle of harmful gases is long, and the environmental performance is relatively poor.
2.Performance: Water-based PU leather performs better in terms of breathability and moisture absorption, and is more comfortable to wear; Oil-based PU leather has more advantages in toughness and elasticity, and has better impact resistance.
3.Application scenarios: Water-based PU leather is suitable for fields with high requirements for environmental performance, such as shoe materials, bags, etc.; Oil-based PU leather is suitable for occasions with high requirements for material properties, such as automotive interiors, furniture, etc.
Conclusion: In practical applications, consumers can choose the appropriate type of PU leather according to their own needs and product usage scenarios. With the development of science and technology and the concept of environmental protection, the share of water-based PU leather in the market has gradually expanded, and it is expected to become a mainstream environmental protection material in the future.
