Product Description
Specifications
Water based foaming agent, used for spray insulationWater based flexible PU foam is an environmental preotection type using water as blowing agent, with good performances of low density(8-10kg/m³), open cell, flame retardant ( B3 grade ) etc.
During spray process in site, the breathing small open cell filled with air, without producing toxic gas to destroy the Ozone layer ( traditional foaming agent: F-11, HCFC-141B), which is enviorment friendly, low- carbon new contruction materials.
This spray PU foam with performances of thermal insulation, gas resistance, damp proof insulation, water proof and sound absorption, it can give us a more quiet, more healthy and more energy saving building.
We use our own products to built our second factory.
