Wiskind has teamed up with the international chemical giant BASF to jointly develop a new generation of PIR sandwich insulation sandwich panel, which adopts the internationally advanced six-component online foaming technology. The dense foam is fully bonded with the surface material to form an uninterrupted heat shield, effectively blocking heat conduction with an excellent thermal insulation performance. Applicable to working temperatures of -170℃-+100℃, the advanced fluorine-free pentane foaming process is able to better protect the ozone layer of our planet from damage.

But why Wiskind and BASF choose PIR not PUR?

As we all know, PUR refers to Polyurethane, and the fire rating of the foam is usually B3 and B2, as it is difficult for it to achieve B1. PUR is characterized by good adhesion, strong physical properties, simple production process, and outstanding panel flatness, but its fire rating is low with heavy combustion smoke. However, PIR is very easy for the foam to achieve a fire rating of B1. PIR is characterized by excellent fire resistance, low smoke index, high oxygen index, better thermal performance, outstanding foam stability and complex process.
