FAQ:1. Please describe this series of products ?
General description:This system is a two component rigid polyurethane foam system which is consist of system polyol and isocyanate. System polyol is fully formulated of polyether polyol,blowing agent,silicone surfactant,catalyst and additives. Widely applied for the insulation of water heater.
2. Please introduce product feature?
a.High volume output efficience
c.fine dimensional stability
d.excellent thermal insulation
e.good flowability and uniform
f.Freon free and pro-environment
g.suitable for all kinds of material injecting way3. How would you pack the products?New steel drums,IBC drums,in bulk or Isotank.
4. How to store the products?
The materials are sensitive to humidity and partially used drums should be tightly sealed to prevent the ingress of moisture.
The system polyol has a shelf life of three to six months from date of manufacture when stored indoors at temperatures of 20-30°C. It is recommended thoroughly mixed before using.
The Isocyanate has a shelf life of one year from date of manufacture when stored indoors at temperatures of 20-30°C. Avoid storage temperatures of below 0°C (as some crystallization may occur) or above 50°C (as formation of insoluble solids may occur).
