PU Polyurethane Resin for Domed 3D Gel Wall Tiles

Conventional polyol is a kind of polyether polyol (polyether polyol is roughly divided into soft foam polyether, rigid foam polyether, CASE polyether and POP series) to produce slab stock foam on continual line for furniture, sleeping mattress and auto seat, etc. It is lumpy, usually soluble in aromatic hydrocarbons, halogenated hydrocarbons, alcohols, and ketones, and has hygroscopicity. It has high activity, good stability, high chain segment strength, and large tolerance to additives.

Conventional polyol is An important polymer raw material, mainly used to make various polyurethane materials. It is also often used in furniture, automobiles, clothing and other industries (but it contains low-molecular aldehydes, alcohols, and shuttle acids, which will produce unpleasant odors).

Production process Under the action of alkaline catalyst, glycerin, propylene oxide and ethylene oxide undergo anionic ring-opening polymerization to form crude polyether polyol, which is neutralized, dried, and filtered to obtain soft foam polyether polyol.
