ELECTRICAL PROPERTIES
Electrical resistance of Epitropic fibre is 10 – 100 Megohms/cm
Approximately 1% Epitropic fibre prevents discomfort from static in everyday clothing and carpets
2 – 5% Epitropic fibre is necessary in fabrics for industrial filters and safety workwear
Resistivity is approximately 1 – 100 Megohms/sq but is dependent on the fabric and its construction

RESISTANCE OF EPITROPIC FIBRE TO CHEMICAL AGENTS
Acids Except under the most extreme conditions the rate of acid hydrolysis is very slow and good resistance to the majority of mineral and organic acids can be expected.
Alkalis Aqueous alkalis except ammonia and its derivatives cause progressive solution of the fibre. Ammonia, quaternary bases, Amines etc degrade the fibre without dissolving it. Maximum level recommended is pH 10.
Oxidising Agents Epitropic fibre has excellent resistance to oxidising agents and withstands bleaching processes.
Reducing Agents Epitropic fibre has excellent resistance to reducing agents
Water / Steam Good
Long term exposure
to dry heat
Excellent
