Product Details
Vspray-3 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 etc.
Physical Properties
Recommended Ratio
Reactivity Characteristics
(The temperature of the system is 20ºC,and the exact value varied depending on processing condition)
