Waterproof Polyurethane Sandwich Panel
Why Polyurethane Sandwich Panel is more Stable than the EPS and XPS Sandwich Panel?
The Polyurethane Sandwich Panel is more stable than the EPS and XPS sandwich panels in the following properties:
Warm Protection Execution
A polyurethane unbending layer has a warm conductivity of 0.028w/m.k, EPS has a warm conductivity of 0.047w/m.k, and XPS has a warm conductivity of 0.058w/m.k.
Thus, the unbending polyurethane froth has the lowest warm conductivity.
Execution of Fixing
EPS and XPS Sandwich Panel is fixed with holes and holes, and outside air can easily pass through the holes and pits, altering the protection execution.
While Polyurethane Sandwich Panel is easy to install, with its compact structure having the great capability to resist humidity and water absorption. It is featured with superb airtightness.
Wind Resistance and the Bearing Limit of the Opposing Block Layer
Polyurethane Sandwich Panel has a thickness range of 40mm to 100mm, bond strength of 0.7MPa, and is fully prepared to support raised structures.
In any event, the dry elasticity of the EPS froth board is just 0.3 MPa, and the bond stiffness after soaking is even lower.
As a result, EPS foam boards cannot be used in most tall structures. Steel wire lattice and plastic nails are also necessary when confronting blocks of towering buildings that are glued.
The polyurethane framework is splashed frequently, its protective solidity is 40 °C, and the size change rate is less than 2%. It is elastic enough for high weightage structures. It can bear a specific weight without breaking.
Before they can be used in the development, EPS froth and XPS must be debased for 60 days, which is difficult to achieve in a functioning application.
As a result of this, numerous cracks, cold infiltration, and halogen return of separators may be discovered in EPS protection projects all over the globe.
Polyurethane Rigid Foam completion rate of 92%, the self-cleaning completion rate of 99.9%, especially make the panel waterproof. The core part is made of organic material, resisting water absorption.
With obstructing voids in EPS, the XPS panel’s core for depression glue, water is not difficult to enter the room through breaks and pits.
Polyurethane foam has self-smothering carbonization for fire resistance, but with consistent flame presence, it can catch the fire. Sudden with flame disappearing, fire will be stopped to explore.
When XPS and EPS come into contact with fire at high temperatures, the liquid drops cause the partition to fall off and the fire to spread.
