Polyurethane insulation board popular seven performance advantages

by:Ventech     2020-12-05
There are many people questioned polyurethane insulation board, where exactly good? Will be sought after by all of us and support, let small make up me today to tell you that because of polyurethane insulation board has the performance of the heat preservation material don't have other advantages.


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.

4, resistance to deformation ability is strong, not easy craze, facing stability and security. Comprehensive cost-effective.

5, while 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 heating and cooling costs are greatly reduced.

6, 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. Can do in the life of the structure under the condition of normal use, in a dry, wet and electrochemical corrosion, and because of the insects, fungi or algae growth or due to external influence, such as the destruction of the rodents are not damaged.

7, 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.

the performance advantages of polyurethane insulation board determines it will be welcomed by all of us, my company specializing in the production of polyurethane insulation board, welcome to choose and buy!
