  Details:
Goldensea are among the leading suppliers of polyether polyols, with a product range and global reach unrivalled by most of our competitors.

 

A polyol is an organic compound containing multiple hydroxyl groups. The term "polyol" can have a slightly different meanings in food science and polymer chemistry. A molecule with more than two hydroxyl groups is a polyol, e.g., with three is a triol, one with four is a tetrol and so on. By convention, polyols do not refer to compounds that contain other functional groups. Cellulose is a polymer with many alcohol groups, but it is not usually discussed as a polyol.

 

A polyether polyol is the polymeric reaction product of an organic oxide and an initiator compound containing two or more active hydrogen atoms. The active hydrogen compound in the presence of a base catalyst initiates ring opening and oxide addition, which is continued until the desired molecular weight is obtained.

 

Polyether polyols' major use is in polyurethane foams. Flexible foams are primarily used in cushioning applications such as furniture, bedding and car seats, and in carpet underlay. Rigid foam's largest consumer is the construction industry where it is mostly used for insulation. Rigid foam is also used in commercial refrigeration and packaging. Smaller uses for polyether polyols include elastomers, adhesives and sealants, surface coatings and polyurethane fibres.

 

Polyether resins, known as polyols, are hydroxylfunctional polymers usually made from the reaction of propylene oxide (PO) and/or ethylene oxide (EO) with an initiator. The hydroxylfunctional polyols are reacted with aromatic or aliphatic diisocyanates to create polyurethane products such as foams, elastomers, sealants or adhesives.
