Polytetrafluoroethylene FLUOROSINT 500 PTFE

Fluorosint®500 PTFE is nine times more resistant to deformation under load than unfilled PTFE. Its coefficient of linear thermal expansion is close to that of aluminum and 1/5 that of PTFE - often eliminating fit and clearance problems. It is 1/3 harder than PTFE, has better wear resistance and maintains low friction properties. Fluorosint® 500 is also not abrasive to most mating materials.

Fluorosint® PTFE Reinforced

The unique properties of Fluorosint PTFE Enhanced come from a special process in which synthetic mica is molecularly linked to pure PTFE through a chemical process. The performance created by this bond is beyond the reach of ordinary reinforced PTFE. The Fluorosint series has good characteristics of low friction and dimensional stability.

Fluorosint® 500 PTFE
Good dimensional stability - good material selection for tight tolerances

Designed with special synthetic mica reinforcement, Fluorosint 500 exhibits good mechanical properties and low friction characteristics in addition to the chemical and hydrolysis resistance of polytetrafluoroethylene (PTFE).

Fluorosint 500 (colour: ivory white) is 9 times stronger than ordinary PTFE in terms of deformation resistance under load pressure. Its linear thermal expansion coefficient is low, similar to that of metal-aluminum, which is only 1/5 of that of pure PTFE. Therefore, when replacing ordinary PTFE, it can solve the gap problem of ordinary PTFE when mating. Fluorosint 500 has higher hardness than pure PTFE, good wear resistance and low friction. Fluorosint 500 is a good non-abrasive engineering plastic that will not cause abrasion to most materials it meshes with.

Fluorosint®500 PTFE Application

Labyrinth Seals and Guards

As a wear-resistant seal, it is used on turbines. In unfavorable chemical environments, seals and shields processed from Fluorosint® 500 PTFE pipes have reliable performance and greatly improve the efficiency of turbomachinery. (Replaces previous materials: Aluminum, Bronze, Babbitt)

Transmission and Power Steering Seals

Because the service performance and service life are obviously better than other PTFE, transmission and power steering sealing rings processed by Fluorosint® 500 have been widely selected by European automobile manufacturers. (replaces previous material: GF PTFE)
