DonSpray504 is spray blend polyols, blowing agent is 245fa instead of HCFC-141B, it reacts with isocyanate to produce foam which has excellent performances, which are as follows, 1) fine and uniformity cells 2) low thermal conductivity 3) perfect flame resistance 4) good low-temperature dimensional stability. It applies to all kinds of thermal insulation engineering which uses the spray technology, such as cold rooms, pots, large-scale pipelines and construction metope etc.Information provided by Shandong INOV Polyurethane Co., Ltd. |
