RULON® PTFE BASED RESINS

 

B.I.R.S. Machine & Supply distributor of proprietary PTFE based resins

manufacturered for seals, bearings, slide bearings and more. Rulon® and

TEKSLIDE is offered in sheet, rod, tube, film, tapes, custom machined

bearings and components.

 

Rulon® is the Saint Gobain Performance Plastics tradename for a family of reinforced proprietary Fluoropolymer PTFE compounds. This unique family of materials offers the combination of high compressive strengths, low coefficient of friction, and excellent abrasion and corrosion resistance while running without lubrication. These materials are used in bearing and seal applications at temperature extremes from -400°F to +500°F (-240°C to +260°C) with or without additional lubricants. Rulon ® materials also have the unique property of no slip stick and no erratic motion at low speeds. Also see TEKSLIDE Fluoropolymer materials.

 

Rulon® J has a PV rating of 7500; which is one of the lowest of all PTFE-reinforced materials.  It is ideally suited for start/stop applications where stick/slip must be eliminated. It is not recommended in steam or otherwise wet environments. When you want low maintenance, self-lubrication, and the lowest coefficient of friction of any PTFE blend, consider Rulon® J. Also see TEKSLIDE G461.

 

Rulon® AR is somewhat more flexible than Rulon® LR, hence suitable for seals and bonded coating of slide surfaces. It has many decades of use in automotive shaft seals and fuel metering pump cups. Rulon AR has a practically universal chemical inertness like that of Rulon LR and provides long life and reliability in continuous non-lubricated service. It is capable of operating at PV values up to approximately 10,000.  Higher PV values are possible for intermittent use applications. Rulon® AR is a light maroon in color. Also see TEKSLIDE G471.

 

Rulon® LR is a maroon colored bearing material best known for its versatile design properties. It is compatible with most hardened steel substrates. Mild steel is acceptable; harder running surfaces are better. Rulon® has a practically universal chemical inertness. Of the chemicals encountered in commercial practice, only molten sodium and fluorine, at elevated temperatures and pressures, show any signs of attack.For continuous non-lubricated service, Rulon LR sleeve bearings are capable of operating up to 10,000 PV. Higher values are possible for intermittent service. Also see TEKSLIDE G732

 

Rulon® 641 is manufactured from FDA compliant materials which possess excellent load and wear characteristics. Rulon® 641 offers excellent, continuous non-lubricated service up to 10,000 PV - higher for intermittent service. While the load capacity of Rulon 641 is generally limited to 1,000 psi at room temperature, deformation is a function of wall thickness, temperature and load. Rulon® 641 compatibility with a wide array of mating surfaces, including mild steel, 303 and 316 stainless steels, as well as harder materials, make it a good choice for most food and pharmaceutical bearing applications. White in color. Also see TEKSLIDE G729.

 

Rulon® W2 is a black PTFE-based material developed for use in fresh-water applications. It exhibits low friction and excellent wear characteristics (one of the lowest wear rates in fresh water) as well as good thermal dissipation, preventing shaft distress. Its properties are enhanced when wet. Rulon® W2 is compatible with most metal substrates and soft mating surfaces. Rulon® W2 is a good alternative to Rulon J when superior chemical resistance is needed. However, it should not be used on very soft mating surfaces or where electrical insulation is desired. Also see TEKSLIDE G456.

 

Rulon® 123 is a glossy black non-abrasive compound for softer mating surfaces, such as stainless steel. This material has excellent chemical resistance and is FDA and USDA compliant. It is less expensive than Rulon J, but is slightly less flexible and higher in wear. It has a high resistance to deformation, low coefficient of friction and good thermal and electrostatic dissipation. Rulon® 123 material has a maximum operating temperature of 550°F (300°C). Rulon® 123  releases black wear debris over time and should not be used in ultra-dry, vacuum applications, or where electrical insulation is desired. Also see TEKSLIDE G412.

 

Rulon® 142 aqua colored low deformation material suitable for linear bearings and slides. Rulon® 142 is a specially formulated dull blue-green linear bearing material that exhibits low wear, high thermal dissipation, and good dimensional stability characteristics. Among its many benefits are the virtual elimination of stick-slip, vibration dampening, self-lubrication, uniform friction, long life, ease of application and design diversity. Rulon 142 has excellent mechanical properties and is the ideal material for machine tool applications. Its low deformation characteristics limit the amount of misalignment that can occur with other bearing materials. Strong acids and bases should be avoided, as they may attack the fillers. See TEKSLIDE® G464.
