Hindustan Nylons Standard Fluoromers Pvt. Ltd. Offers Amorphous Carbon Fibre made Fillers. Hindustan Nylons Standard Fluoromers Pvt. Ltd. Is an ISO 9001:2008 accredited company. The Amorphous Carbon Fibre made Fillers is one of the most inert fillers, except in oxidizing environments where glass performs better. Carbon adds to the creep resistance, increases the hardness and raises the thermal conductivity of PTFE. Carbon filled compounds have excellent wear properties, in particular when combined with graphite. The combination of the above properties makes carbon/graphite compounds the preferred material for non-lubricated piston rings. The use of softer carbon has the additional advantage that it lowers tool wear during machining, thus allowing machining to very close tolerances. Carbon-containing compounds have some electrical conductivity and are therefore antistatic.
