The basic building block
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.
Polyether Polyols (PEOL) are marketed under Lupranol® and Pluracol®. The portfolio includes conventional PEOLs, as well as polymer PEOLs.
Polyester Polyols are marketed under the name Lupraphen®. Both aliphatic and aromatic grades are available. They are combined with isocyanates to produce semi-rigid PU plastics.
