The use of polyurethane composite board: with the continuous development of polyurethane and improvements, the application of polyurethane has deep into the aspects of our lives.

1, rigid polyurethane low thermal conductivity, good thermal performance. When the density of rigid polyurethane as 35 ~ 40 kg/m3, the coefficient of thermal conductivity is only 0. 018-0. 024w/( 该调查) , or the equivalent of about half of the EPS, it is the lowest all heat preservation material coefficient of thermal conductivity.

2, rigid polyurethane has moisture-proof and waterproof performance. Rigid polyurethane obturator rate above 90%, belong to the hydrophobic material, not due to the increased moisture absorption coefficient of thermal conductivity, metope also won't ooze water.

3, rigid polyurethane fire, flame retardant, resistance to high temperature. After adding flame retardant polyurethane, is a kind of flame retardant material, self-extinguishing its softening point can reach more than 250 degrees Celsius, will appear only in high temperature decomposition: in addition, when burnt, polyurethane form carbon deposition in the bubble surface, the carbon deposition help under the isolation layer of froth. Can effectively prevent the fire spreading. Moreover, polyurethane also does not produce harmful gases at high temperature.

polyurethane composite board application such as car production, mining beneficiation, port terminals, food and food processing, medical and health care, construction machinery, electronic equipment, construction, furniture, textile and garment industry, synthetic leather, water conservancy, petroleum chemical industry, printing and packaging, sports fitness industry has a large number of applications, as technology advances, polyurethane on our aerospace, defense industry step by step to obtain the very good application. http://www。 juanzhibwb。 com/
