Fluorosint

Fluorosint's unique properties are the result of a proprietary process in
which synthetically manufactured mica is chemically linked to PTFE. This
bonding results into a load carrying capability and thermal expansion rate
not normally attainable in reinforced PTFE. The chemical and temperature
resistance inherent in PTFE are practically retained.

Fluorosint 500 (Reinforced Polytetrafluorsethylene (PTFE) + mica) ivory

Fluorosint 500 has nine times greater resistance to deformation under load
than unfilled PTFE (tested according to ASTM D 621; stress of 14 MPa of
50°C). Its coefficient of linear thermal expansion approaches the expansion
rate of aluminium and is 1/5 that of virgin PTFE. It is considerably harder
than virgin PTFE, has better wear characteristics and maintains low
frictional properties. Fluorosint 500 is also non-abrasive to most mating
materials.

Common Uses for Fluorosint

Fluorosint 500 Labyrinth and shroud seals

Seals made from aluminium, bronze or Babbitt caused mating part wear that
decreased the efficiency of turbo compressors. Redesigned abradable seals
machined from Fluorosint 500 tube dramatically improved efficiency and
helped protect other parts from damage. Fluorosint's excellent chemical
resistance and forgiving composition can greatly improve the performance of
rotating equipment while dealing with shaft movement and pressure changes
that can damage metallic seals.
