Polyurethane insulation board performance is introduced

by:Ventech     2020-12-02
With the high-speed development of economy and the constant innovation of science and technology, the application scope of polyurethane insulation board is more and more widely, today small make up this article will focus on the performance of polyurethane insulation board

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, due to the pu board with excellent insulation properties, under the same heat preservation requirements, and can make to reduce the thickness of the building envelope, to increase the indoor use area.

3, 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.

4, comprehensive cost-effective. Although the rigid polyurethane foam material unit price is higher than other traditional heat preservation material unit price, but the cost of the increase will be offset by the reduction of heating and cooling costs and.

5, resistance to deformation ability is strong, not easy craze, facing stability and security.
6, 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.

7, polyurethane material porosity structure stability, is essentially closed pore structure, not only the heat preservation performance is good, and freeze resistance, sound absorption. The average life expectancy of hard foam polyurethane insulation structure, under the condition of normal use and maintenance, can reach more than 30 years.

to see this article, to understand the performance of polyurethane insulation board is so strong, the friend in need can contact us.
