Rigid Polyurethane Foam (PUR)

PUR is a foaming material produced by the reaction of isocyanate with polyether in the presence of a catalyst. Its physical and fire resistance is superior to that of general polyurethane, making it an ideal organic low-temperature insulation material with low thermal conductivity, lightweight, vibration resistance, and strong adaptability. It is widely used in refineries, chemical plants, ethylene, fertilizers, cold storage, and building insulation.

4. Precautions

Do not use on frosty or damp substrate surfaces.

Construction is not advisable when material surface temperature is below 0℃ or above 50℃;

Components A and B must be thoroughly mixed to avoid unevenness that could affect the performance of the elastic material;

Components A and B should be stored separately and used as mixed, to avoid waste, mix only when needed;

For adhesion-related construction, check adhesion performance beforehand and contact relevant technical service departments if needed;

Direct contact with eyes and skin may cause temporary discomfort; in such situations, rinse with plenty of water and seek medical attention if necessary.
