0 Odp Blend Polyol for Pipe Injection Insulation Rigid PU Foam System
SDP2207 is a kind of blend polyol used for rigid PU foam spray, specially used for the insulation of polyethylene winding prefabricated directly buried pipes. When it combined with isocyanate(PM200) leads to the formation of rigid polyurethane foam by using PU spray machine. The foam formed has the characteristics as following:
1.Zero ozone depleting blowing agent.
2.Convenient construction and uniform density.
3.The low thermal conductivity, low water absorption, good insulation performance, high compressive strength and good dimensional stability.
4.Low-cost and long service life.

USAGE ATTENTIONS:
·It is necessary to increase the mixing pressure of the equipment or increase the heating temperature of blend polyo, isocyanate or
pipeline, before using the equipment, it is necessary to carry out material circulation.
·During the material circulation, check for leaks and blockages, and calibrate the flow rate of the metering pump.
·The basis for judging the mixing effect of raw materials is that the color of the core is uniform, fine porosity, no glass bubbles, and
no obvious pinhole phenomenon on the surface of the foam.
·The surface of the steel pipe should be dry, free of dust and oil stains.
·The blend polyol and isocyanate should be stored in the sealed container to avoid the absorption of water vapor. During the
transportation, it should avoid serious shake and strong sunlight. It should be stored in ventilated place, avoiding light, water and
fire.
·Recommended storage temperature for blend polyol is 15~30ºC.
·Recommended storage temperature for isocyanate is 15~35ºC,it can be heated by electric stove or heating belt in winter
