Polyurethane shoe material is light in weight, wearable and comfortable, and is well received by the market; it has a special microporous structure, and the polyether polyol used is different from the conventional products in the market. By designing the molecular chain structure of polyether polyols, we obtain special polyether polyols with different functionalities and adjustable reactivity (adjustable from low to high) with narrow molecular weight distribution and low VOC. The relevant properties are similar to those of imported polyether polyols. Such polyether polyols are widely used in polyurethane sole slurry, which can reduce the amount of catalyst, improve the molding shrinkage of the sole, obtain a good microporous structure, and improve the wearing comfort of the shoe material, especially in the field of low density polyurethane sole materials. Or missing.

At present, our company's high-activity polyether polyols for shoe materials mainly include the following products:

Brand	Moisture （%）	Hydroxyl value（mgKOH/g）	Acid value （mgKOH/g）	K+ （≤ppm）	Chroma （APHA）	use
SD-5601	≤0.05	54-58	≤0.05	5	≤35	Polyurethane sole material, microcellular elastomer, etc.
SD-2802	≤0.05	26-28	≤0.05	5	≤35
SD-820	≤0.05	26-30	≤0.05	5	≤35
SD-2003	≤0.05	55-57	≤0.50	5	≤35
