Polymeric polyols are an important group of monomers which are generally used to produce other polymers. They react with isocyanates to give various kinds of polyurethanes. There are many kinds of polyols, which will give polyurethanes with different properties for different end applications such as mattresses, foam insulation for appliances, home and automotive seats, elastomeric shoe soles, fibers and adhesives. Polymeric polyols are usually polyethers or polyesters. Polyether polyols are produced in a catalysed batch process by reacting various chain starters with propylene oxide (PO) and/or ethylene oxide (EO) in the presence of a catalyst.
Some of the process features are;
High productivity with high flexibility in batch size and variety of polyols that can be produced
High product quality
Very high yield, more than 99.9 % based on chain starter PO and EO
Low environmental impact
Minimum plot area
