Pure PTFE Flat Washer Backup Ring / Mechanical White Seal Ring Pump Parts
PTFE (Polytetrafluoroethylene)
Known as the gold standard, PTFE material is often the first choice
for many advanced applications such as aerospace, electronic,
medical, chemical industry due to its superior lubricity,
temperature and chemical resistance, biocompatibility and lowest
coefficient of friction.
Properties
1, Low coefficient of friction;
2, Flexibility at low temperatures and thermal stability at high
temperatures,Broad working temperature range (500°F/260°C –
-292°F/-180°C);
3, Chemically resistant – all normal solvents, acids, and bases;
4, Low dielectric constant and low dissipation factor;
5, Non-flammability;
6, Non-stick, Easy to clean;
7, Long-term weathering;
8, High arc resistance, surface and volume resistivities

Back-up Rings have no intended sealing function.
They are protective and supporting elements made from
extrusion-resistant materials which generally have a rectangular
cross section. They are installed in a groove together with an
elastomeric sealing element preferably with a corresponding O-Ring
in static applications.Due to the tight fit of the Back-up Ring in
the housing, they prevent extrusion of the pressurised elastomeric
sealing element into the sealing gap.
