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.
