Rigid polyurethane foam shell
Product Description:
Rigid polyurethane foam tiles (pipes): for a variety of indoor and outdoor pipes, central air conditioning ducts, chemical, pharmaceutical and other industrial pipe insulation, cold.
High functionality polyether polyols and several multi-methyl-phenyl isocyanate over as the main raw material, catalyst, blowing agent, surface active agent under the effect of foam formed by chemical reflected.
Polyurethane products have the capacity of light, high strength, heat insulation, sound insulation, fire-retardant, cold, corrosion, non-absorbent, easily and quickly so excellent construction features, has become the construction, transportation, petroleum, chemical, electricity, refrigeration and other industrial sectors thermal insulating, waterproof plugging, sealing and other essential materials.
Polyurethane rigid foam buried pipe for central heating pipes, all kinds of refrigeration and industrial piping.

With isocyanate, polyol (polyether or polyester mix) as the main raw material additive composition of the two-component, through the construction site with a waterproof coating and insulation features rigid foam. On-site spray applied polyurethane hard foam construction insulation body of the non-exposed waterproofing materials. Its thermal conductivity is low, only 0.018 0.024W / (m 8226 k), equivalent to half of EPS, which is the insulation material of all the lowest thermal conductivity, and thermal performance is good, also has anti-aging, chemical stability, excellent waterproof moisture, heat does not melt and so on. Executive Standard: JC / T 998 - 2006, JGJ14 - 1999, GB10800 - 1989.
