Polyurethane synthetic leather has a wide range of products for its excellent comprehensive performance (performance close to leather). Solving the breathability of polyurethane synthetic leather and making polyurethane synthetic leather more environmentally friendly are the problems faced by polyurethane synthetic leather manufacturers.

The polyether polyol used in polyurethane synthetic leather produced by our company has a high primary hydroxyl end-cap content, which makes it have excellent reactivity with isocyanate, reduces the amount of catalyst used, and meets the requirements of green environmental protection. And through the adjustment of the hydrophilic segment in the polyether polyol, a special structure of the polyether polyol is obtained, so that the synthetic leather obtained is more breathable and has comfortable wearing property. Such polyether polyols are widely used in the field of polyurethane synthetic leather, especially in high-end synthetic leather products, solvent-free leather, artificial leather and other related fields.

At present, our company's high-activity polyether polyol for synthetic leather mainly includes the following products:

Brand	Moisture （%）	Hydroxyl value（mgKOH/g）	Acid value （mgKOH/g）	K+ （≤ppm）	Chroma （APHA）	use
SD-2802	≤0.05	26-28	≤0.05	5	≤35	Synthetic leather
SD-820	≤0.05	26-30	≤0.05	5	≤35
SD-2003	≤0.05	55-57	≤0.50	5	≤35
