New Arrival China Doncool 103 Cp/Ip Base Blend Polyols - Donspray 504 HFC-245fa base blend polyols – INOV Detail:
Donspray 504 HFC-245fa base blend polyols
INTRODUCTION
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.
