Polyurethane Dispersion Used For Bonding Layer Of Artificial
Leather
Description
People are accustomed to using water-based PU resin (polyurethane
dispersion) as the raw material for artificial leather called
water-based PU artificial leather (water-based PU leather);
water-based PU resin and non-woven fabrics used as raw materials
for artificial leather called water-based PU synthetic leather
(water-based synthetic leather). It shows a kind of essential
beauty, which embodies the taste of “plain face to sky”. The
softness, rigidity, warmth, and apathy of the material itself not
only affects the senses and spirit of the person.
Properties and characteristics:
1. High strength, thin and flexible, soft and smooth, good air
permeability, no odor, and waterproof.
2. It still has good tensile strength and disturbance strength at
low temperature, and has good light aging resistance and hydrolysis
resistance stability.
3. Abrasion resistance, appearance and performance are close to
natural leather, easy to wash and stain, easy to sew.
4. The surface is smooth and compact, and can be used for various
surface treatments and dyeing. The variety and price are relatively
low.
5. Water absorption is not easy to swell and deform.6.
Environmental protection, zero emissions of hazardous chemicals.
