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.
What is butane? Butane is a hydrocarbon and a highly flammable, colourless, odourless, easily liquefied gas. It is typically used as fuel for cigarette lighters and portable stoves, a propellant in aerosols, a heating fuel, a refrigerant, and in the manufacture of a wide range of products. Butane is also found in Liquefied Petroleum Gas (LPG). Since 1987, hydrocarbons have replaced chlorofluorocarbons (CFCs) as the propellant used in most aerosols. Butane is one of the commonly used propellants in household and industrial aerosols and therefore can be found in numerous aerosol products. However, the packaging of many aerosols products will commonly identify the propellant as âhydrocarbonâ, not specifically identifying butane.
