Roof panel manufacturer: thermal insulation performance of polyurethane composite board

Rigid polyurethane has low thermal conductivity and good thermal performance. Polyurethane composite plate has high elasticity and strength, excellent wear resistance, oil resistance, fatigue resistance and seismic resistance in a wide range of hardness, and is known as "wear-resistant rubber". Although the output of polyurethane elastomer in polyurethane products is small, polyurethane elastomer has excellent comprehensive performance and has been widely used in metallurgy, petroleum, automobile, mineral processing, water conservancy, textile, printing, medical treatment, sports, grain processing, construction and other industrial sectors. When the density of rigid polyurethane is 35~40 kg/m3, the thermal conductivity is only 0.018~0.024w/(M.K), about half of that of EPS, which is the lowest among thermal insulation materials at present.
Rigid polyurethane has waterproof and moisture-proof properties. Polyurethane composite plate has high elasticity and strength, excellent wear resistance, oil resistance, fatigue resistance and seismic resistance in a wide range of hardness, and is known as "wear-resistant rubber". Although the output of polyurethane elastomer in polyurethane products is small, polyurethane elastomer has excellent comprehensive performance and has been widely used in metallurgy, petroleum, automobile, mineral processing, water conservancy, textile, printing, medical treatment, sports, grain processing, construction and other industrial sectors. The airtight porosity of rigid polyurethane is more than 90%, which belongs to hydrophobic material. Moisture absorption will not increase the thermal conductivity, and the wall will not seep. {+*/} With its unique performance advantages, polyurethane composite board has occupied a place in the fierce competition in the insulation material market, which is no accident.
