POLYOLS AND POLYOLS USES

Polyether Polyols are made by reacting organic oxide and glycol.

Main organic oxide utilized are Ethylene Oxide, Propylene Oxide, Butylene Oxide, Epichlorohydrin.

Main glycols utilized are Ethylene Glycol, Propylene Glycol, Water, Glycerine, Sorbitol, Sucrose, THME.

Polyols contain reactive hydroxyl (OH) groups which react with isocyanate (NCO) groups on isocyanates to form polyurethanes.

There are many kinds of polyether polyols for polyurethane. PU materials with different performance can be obtained with the reaction between different initiators and olefin polymerization.

By modifying the PU raw materials or changing the catalyst, polyether performance can be modified. These initiators include diethyl alcohol, ternary alcohol, tetrahydrofuran, and aromatic polyether polyols, etc.

USES

The consumption of polyether used in PU is more than 80%. Polyether polyurethane can be classified

Polyether Polyol (PPG),

Polymeric Polyol (POP),

Polytetramethylene ether glycol (PTMEG, also called polytetrahydrofuran polyol) according to the initiator.

Polyether polyols are mainly used in PU rigid foam, soft foam, and molding foam products.
