Donspray 501 water base blend polyols

Donspray 501 water base blend polyols

INTRODUCTION DonSpray 501 is a two-components, spray-applied, open-cell polyurethane foam system. This product is fully water-blown foam system with good performances of low density ( 8~10kg/m3), open cell and fire resistance Class B3. During spray process in site, the breathing small open cell filled with air, without producing toxic gas to destroy the Ozone layer( traditional blowing agent: F-11, HCFC-141B), which is environment friendly, low-carbon new construction materials. With highly performance of thermal insulation, moisture & vapor barrier, air barrier, sound absorption, PU foam can give us a quieter, more energy saving buildings leading us to a healthier life.
