PTFE film and sheet materials represent a significant share
of the total output of PTFE items. Major consumers of these
products include electrical, radio electronics and
instrument-making industries where film materials are used for
manufacturing cables and capacitors, as well as packing, sealing
and lining materials. Fluoroplastic films are widely used in
electrical and SHF equipment because they demonstrate very good
performance in electrical systems. PTFE's high thermal resistance
ensures good reliability and long operational life of cabling with
thin insulation.
In accordance with GOST 24222-80 (Russian standard), the
following types of films are fabricated:
- capacitor oriented film is used in capacitors (KO);
- electrical insulating oriented film is intended for use as an
insulating material for wires and cables (EO);
- electrical insulating non-oriented film is intended for use as
an insulating material for wires and cables (EN),;
- insulating oriented film (IO);
- insulating non-oriented film is intended for use as an
interlayer electrical insulating material in instruments and
components (IN);
- gasket non-oriented film is intended for use as packing,
sealing and insulating material.
Our company can fabricate PTFE gasket films and tapes (in
accordance with GOST 24222-80) with a width of 20 to 150 mm and
thickness of 0.2 to 2.6 mm (see the product range in the
table).
Tapes made from PTFE-based compounds such as F4Ê15Ì5 and F4Ê20
should be used in heavy-duty bearings with high initial
deformation. They should also be used for making self-lubricating
guide and piston rings.
These tapes ate fabricated using the method of continuous
skiving of a sintered blank made from a PTFE-based compound. The
standard sizes of our tapes are specified in the table.
