Fibrous filtering material FPP-D

FPP-D is intended to equip valve and damper devices in pneumoautomatics, for thin air and gases clearing, for fabrication of analytical AFA type filters.

FPP-D can be utilized for thin clearing of suspended mechanical impurities from fluids, fuels and oils, and for the fabrication of fuel quality indicators.

FPP-D is like a tight, uniform fibrous layer of white colour composed of ultra thin fibres, connected at locations of intersection. Due to the properties above, the material has a smooth, non-fuzzy surface and tight structure.

FPP-D is hydrophobic, stable to acids, weak alkalis, solutions of salts; is not diluted in alcohol, hexane; diluted in dichlorethane, tetrachlorethane, chlorobenzol, toluene, xylol, tetrahydro-furan; swelled in four-chloride carbon, benzol, dibutilftalate, tricresilphosphate.
