LPG concentration influence on straw applied winter PU OCF,Used
Delivery time: 8-12 business days (International)
The goal of the present book is to determine the influence of the liquefied petroleum gases (LPG), such as propane, nbutane and isobutane, on straw applied winter (B3 highly flammable) one component polyurethane foams. The experiments, were made at +23/+23 C (can/spray temperature), +5/5 C and 10/10 C, 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 C and output at +5/5 C. Further experiments were made to determinate the dimensional stability of the foams, physical tests of compression and adhesion, postexpansion 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 C were not as so good as the formulation present in the market.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
