Every one of us has held something made of PUR at some time. For example, your car’s steering wheel, a football, wellington boots or a mattress are just a few examples of the possible uses of this multi-faceted plastic in our everyday lives. Do-it-yourselfers and craftsmen know PUR as a construction foam. But the experts draw a clear distinction between soft foam and hard foam products. In the industry, hard polyurethane foam is often used as a insulating and damping material in “sandwich” constructions. These elements consist of inner and outer metal composites. The space between them is filled with PUR foam, which expands during the reaction. With its excellent insulating properties, PUR is the ideal substance for significantly improving the energy balances in buildings, for example. The contribution PUR has been making to the reduction of climate gas emissions for years should not be underestimated. For example, the PENTANE PROCESS TECHNOLOGY (PPT) from Hennecke replaced the greenhouse gas CFC in refrigerators, and is one of the primary reasons why there are now refrigerators with energy class A++. Although polyurethanes are manufactured from a petroleum base, they are endowed with such exceptional product properties that they help to conserve many other resources. For instance, heating and cooling needs are reduced by the insulating characteristics mentioned previously. This lowers CO2 emissions. PUR is the most commonly used plastic in the car building industry, and is indispensable for improving comfort and texture in an enormous variety of applications. PUR is also major factor in automotive applications where weight reduction is important, because less weight means less fuel consumption. And to top it all off, PUR is recyclable and can be processed to make new products.
