WebAbout Polyether Polyurethane. Polyurethane (a.k.a. PU) are a group of polymers with great industrial importance. Polyurethanes are produced by the polyaddition of polyisocianates with polyalcohols, forming the characteristic urethane group as chain link. Its most popular end-products are flexible and rigid foams. WebPolyurethane foam is characterized by its light weight, resilience, low odor, and high resistance to mildew. In comparison to Ester, Ether-based polyurethanes are more flexible, better in wet environments and more affordable to produce. Ether foams have larger cell structures than ester, which allow greater airflow and moisture permeability.
