Rigid polyurethane low thermal conductivity, good thermal performance. When rigid polyurethane density 35 ~ 40kg / m3, thermal conductivity is only 0.018 ~ 0.024w / (m.k), equivalent to about half of the EPS, is the thermal conductivity of the insulation material of all the lowest. Rigid polyurethane with moisture, water resistance. Closed-cell rigid polyurethane rate is above 90% polyurethane board manufacturers, are hydrophobic polyurethane board material does not absorb moisture due to increased thermal conductivity of polyurethane sheet metal factory, the walls are not seepage. Polyurethane composite panels in the international arena has been used as the main steel building envelope materials, widely used in large industrial plants, cold storage, garages, mobile homes, exhibition halls, stadiums, shopping malls, airports, power plants, villas, hospitals, and senior stratum office buildings and other fields, its excellent insulation properties are mainly used in industrial and civil buildings roof and wall. Good thermal insulation: automatic compacting Bumian tracked by long double precision control molding composite, compared with traditional polyurethane boards hanging cotton envelope material prices, better insulation performance is more durable, easy to install, elegant appearance. Rockwool low thermal conductivity (λ = 0.043w / m · k), good insulation properties. Excellent node design ensures sealing performance and insulation effect. Polyurethane sheet, Tsinghua plastic (certified), polyurethane panels provided by the Engineering Plastics Co., Tsinghua ShangYinXian. ShangYinXian Tsinghua Engineering Plastics Co. (www.tyqhgc.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
