Product Description
Description
SY-Spray435 blend polyols with HFO as blowing agent, it reacts with isocyanate to produce foam which has good performances:
1-fine and uniformity cells
2- low thermal conductivity
3-perfect fire resistance
4- excellent low temperature dimensional stability.
Suitable for all kinds of thermal insulation projects,such as cold room, large tank, large pipeline, external wall or internal wall and other use of spray insulation projects.
Pphysical property
COMPONENT 1-Blend polyol
COMPONENT 2-Polymeric MDI
RECOMMENDED RATIO
(The temperature of the system is 20ºC,and the exact value varied depending on processing condition)
Foam performances
The above testing data have been generated in lab or field conditions which are typical for this application. They are believed to be correct but data variations due to varying processing or ambient conditions can not be excluded. The customer remains responsible for making his own interpretation of data and suitability of the chemicals to his particular operation.
