ZHD8003 is a kind of blend polyol used for pipe insulation system for pipeline anti-corrosion and thermal insulation . When it combined with isocyanate leads to the formation of rigid polyurethane foam by using PU injection foam equipment .The foam formed has the characteristics as following
1. The thermal conductivity is low, which can meets the requirements of city heating and energy saving.
2. Service life of the foam is very long lasting.
3. High temperature resistance and good dimensional stability of the foam, the highest temperature range is 140 ºC.
4.The Product also have a high strength.
ADDITIONAL INFORMATION
1. Before foaming,The ratio column of the two components must be checked,Moreover, The operator should reset the radio for a period of time.t
2. ZHD8003 and Polymeric MDI should be controlled temperature, Prevented the summer temperature being too high,and heated in winter.
3. Exhaust before operation, and to avoid polyurethane foam escaped from cracks.
