Glass fibre papers Type MN QF-10

Recommended filters for atmospheric pollution control and for particles determination at high temperatures.Filters made of pure quartz microfibre (SiO2), free of binding elements or additivesExtremely low content in alkali-earth metalsDetermination of suspended particles (SPM and TSP) in ambient air acc. to the directive of the US EPA (Environmental Protection Agency) and the EN 23210Retention: Excellent retention of very fine particles through the adsorption mechanisms of quartz fibresChemical stability: excellent stability with hardly any loss of filter-material due to chemical reactions under extreme conditions with acid gases (HCl, SO2, SO3, H2SO4, NO and NO3)Resistance to chemical reagents: excellent resistance to solvents, acids (except HF) and alkaline substancesStability at high temperatures: higher resistance than glass microfiber, up to 1000 °CWeight: 85 g/m2Thickness: 0.45 mmFurther sizes on request.
