The goal of the present book is to determine the influence of the liquefied petroleum gases (LPG), such as propane, n-butane and isobutane, on straw applied winter (B3- highly flammable) one component polyurethane foams. The experiments, were made at +23/+23 ºC (can/spray temperature), +5/5 ºC and -10/-10 ºC, and intended to determinate the foam quality. At each temperature, where made the Quick Tests, in which was sprayed the foam on the paper and mould, check the overall density mould at +23/+23 ºC and output at +5/5 ºC. Further experiments were made to determinate the dimensional stability of the foams, physical tests of compression and adhesion, post-expansion and yield of a can. The results show that, the formulations made present overall excellent properties comparing to the benchmark one. However, can shaking rates at -10/-10 ºC were not as so good as the formulation present in the market.

Liquefied Petroleum Gas

Liquefied petroleum gas (also called LPG, GPL, LP Gas, or autogas) is a mixture of hydrocarbon gases used as a fuel in heating appliances and vehicles, and increasingly replacing chlorofluorocarbons as an aerosol propellant and a refrigerant to reduce damage to the ozone layer, inferring that it is flammable.Varieties of LPG bought and sold include mixes that are primarily propane, mixes that are primarily butane, and the more common, mixes including both propane (60%) and butane (40%), depending on the season in winter more propane, in summer more butane. Propylene and butylenes are usually also present in small concentration. A powerful odorant, ethanethiol, is added so that leaks can be detected easily. The international standard is EN 589. In the United States, thiophene or amyl mercaptan are also approved odorants.
