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.
CHARACTERISTICS
1. Surface density - 40± 5 g/m2
2. Resistance of material to air flow at a velocity 1cm/c - 10± 2 Pа
3. Penetration rate on an oily fog, with particles having an average radius of 0.14-0.17 ?m at filtration
4. velocity 170 cm/s – at most 20 %
Sizes of a fabric; mm: length1480+20-30, width - 680+20-30
The conformity of FPP-D to the technical requirements is guaranteed for a period of 10 years from the time of fabrication, in the case of the observance of conditions of storage by the consumer.
