Introduction polyurethane insulation Specification: a light density polyurethane insulation, high strength, heat insulation, sound insulation, fire-retardant, cold, corrosion, non-absorbent, quick and easy construction and other outstanding features, has become the construction, transport, petroleum, chemical, power , refrigeration and other ... Product Detail polyurethane insulation Specification: 1, good insulation properties of polyurethane buried pipe insulation, heat loss is only 25% of the traditional pipe, long run can save a lot of energy, significantly reduce energy costs. 2, highly waterproof and corrosion resistance, without attached trench can be directly buried in the ground or water, construction easily and quickly, and lower total cost. 3, at low temperatures also have good corrosion resistance and impact resistance, and can be directly buried underground permafrost. 4, the service life of up to 30 - 50 years, proper installation and use can make the pipe network maintenance costs low. 5, the service life of up to 30 - 50 years. Diameter: DN15 - DN600 Thickness: 15--50mm Uses: central heating pipes, cooling pipes, industrial pipes. 6, the oxygen index: ≥27 Density: 40--70kg / cubic m Hydrophobic rate: 0.03kg / cubic cm Thermal conductivity: 0.022kcal / mh ℃ Polyurethane Unit Index fiberglass unit capacity index compressive strength 40-60 MPa 120- thermal conductivity of 220 W / mk kg / m2 heat resistance and compressive strength MPa 210-355 MPa 25 ℃ ≤120 surface hardness of the surface of the adhesive strength KPa ≥200 gel content> 45% compressive strength KPa ≥200 ammonia condensate KPa 400- 900 Water absorption kg / m2 ≤0.2 life of 30 - 50 years of polyurethane insulation standard types of polyurethane buried pipe insulation is an ideal heating and cooling of laying the pipeline, with saving investment, land conservation, landscaping, City, about energy, safe operation, operation and maintenance cost savings and other advantages, praised by users, any number of users to use practice and related testing center life up to 50 years.
