Donspray 502 HCFC-141b base blend polyols

INTRODUCTION

DonSpray 502 is spray blend polyols with HCFC-141B as blowing agent, 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 fire resistance

4) excellent low temperature dimentional stability.

It applies to all kinds of thermal insulation projects which use the spray, such as cold rooms, large pots, large-scale pipelines and construction out-wall or inner-wall etc.
