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.
There is some potential for confusion as the word urethane on its own is often used for a specific carbamate also called ethyl carbamate, but despite the name, this substance does not appear in the foam. Perhaps the best known use of urethane foam is in bedding, such as mattresses. Because it is artificial, the foam can be made to a particular density, meaning manufacturers can offer a range of mattresses with different degrees of softness or firmness and even produce a mattress to order.
