Polyurethane foams are now used in high-temperature oil filter applications. Polyurethane foam (including foam rubber) is sometimes made using small amounts of blowing agents to give less dense foam, better cushioning/energy absorption or thermal insulation.on-isocyanate based polyurethanes (NIPUs) have recently been developed as a new class of polyurethane polymers to mitigate health and environmental concerns. Polyurethane products often are simply called âurethanesâ, but should not be confused with ethyl carbamate, which is also called urethane.
From Wikipedia, the free encyclopedia. Urea-formaldehyde, also known as urea-methanal, so named for its common synthesis pathway and overall structure, is a non-transparent thermosetting resin or plastic, made from urea and formaldehyde heated in the presence of a base.These resins are used in adhesives, finishes, particle board, MDF, and molded objects.rea-formaldehyde foam insulation (UFFI) dates to the 1930s and made a synthetic insulation with R-values near 5.0 per inch. It is basically a foam, like shaving cream, that is easily injected into walls with a hose.
