The advantages of polyurethane polyurethane sieve sieve is a kind of polyurethane raw materials to produce polyurethane products polyurethane board processing, porous sieve have crack, rectangles, circles, etc., has excellent abrasion resistance, oil, hydrolysis resistant bacteria, anti-aging properties, can be used in coal preparation plant, coking plants, mines, power plants, low thermal conductivity of rigid polyurethane polyurethane panels made to order, good thermal performance. When rigid polyurethane density 35 ~ 40kg / m3, thermal conductivity is only 0.018 ~ 0.024w / (m.k) polyurethane board manufacturers, equivalent to about half of the EPS, and is all the lowest thermal conductivity of insulation materials a. Rigid polyurethane with moisture, water resistance. Rigid polyurethane closed cell rate of 90% or more, are water-repellent material, will not absorb moisture increases the thermal conductivity, the wall is not water seepage.
