Characteristics and effect of rigid polyurethane insulation pad
Thermal insulation performance
Hard polyurethane insulation pad has low thermal conductivity and good thermal insulation effect.
Compression resistance and creep under long-term load
The compressive strength of rigid polyurethane insulation pad is very high, and the creep under long-term load is extremely small. It is sufficient to bear the pressure of the column foot of the overall steel structure for a long time, and there is no possibility of temperature insulation performance decline and damage due to the compression, deformation or breaking of the thermal insulation material.
Resistance to water and moisture
Hard polyurethane insulation pad has a close closed cell honeycomb structure, chemical properties are also very stable, so the water resistance is very good, its water absorption rate < 1% (V/V). Even if it is completely immersed in water, the compressive performance is almost unchanged.
Tensile properties
The rigid polyurethane insulation pad has good tensile properties. The breaking strength of wall pad is about 4MPa, and the elongation at break is about 10.86%. The breaking strength of the column pad is about 6MPa, and the elongation at break is about 10.3%.
Dimensional stability
The dimensional stability of rigid polyurethane insulation pad changes very little, and the rate of change in three directions of length, width and thickness is less than 1%.

Polyurethane Sprayed Thermal Insulation
(WANEFOAM ®6000 Series)
Small thermal conductivity: indoor ice and snow venues are low-temperature and high-humidity buildings, with temperatures ranging from -1C to -8C and indoor humidity above 60%. Therefore, thermal insulation materials with good thermal insulation performance, low volume water absorption and small long-term thermal attenuation shouldbe selected first.
Green environmental protection:
Good flame retardant effect: the thermal insulation materials of indoor ice and snow venues should meet the national requirements for fire prevention.
Good dimensional stability: the thermal insulation material with poor dimensional stability may have cavities at corners and junctions after cooling and shrinkage, forming no thermal insulation area, leading to serious condensation problem.
Easy site construction: site construction quality seriously affects the thermal insulation durability performance, so we should choose the thermal insulation scheme that is easy to site construction.
