1, polyurethane board fire, flame retardant, high temperature. Polyurethane is a non-flammable self-extinguishing material with a flame retardant added. It softens above 250 ° C and decomposes only at higher temperatures: Polyurethanes, on the other hand, The surface is gray, which helps insulate the underlying foam. Can effectively prevent the spread of fire. Also, polyurethanes do not produce harmful gases at high temperatures.
2, anti-deformation ability, not easy to crack, finishes stable, safe.
3, the porosity of polyurethane material structure is stable, basically closed-cell structure, not only excellent insulation properties, but also freeze-thaw resistance, sound absorption Ye Hao. Rigid polyurethane insulation structure of the average life expectancy, under normal conditions of use and maintenance, can reach more than 30 years. Can be done under normal conditions of service life under dry, wet or galvanic conditions as well as due to the higher unit price of insect, fungus or algal foam than other traditional insulation materials, but the additional cost will be raised by heating And a substantial reduction in cooling costs and offset.
4, polyurethane cold plate, with moisture, water resistance. The rigid polyurethane closed cell rate of 90% or more, are hydrophobic materials, will not increase the thermal conductivity due to moisture absorption, the wall will seep water.
5, due to the excellent thermal insulation properties of polyurethane materials, to achieve the same insulation requirements, can reduce the thickness of the building envelope, thereby increasing indoor use area.
6, high-precision cutting, the thickness error is 0.5 mm, thus ensuring the finished product surface roughness.
7, convenient quality inspection, due to the removal of the skin during the cutting process, the quality of the plate at a glance, to ensure the insulation effect of finished products.
