Omniseal Solutions PTFE-FILLED FLUOROPOLYMER MATERIALS BEYOND wiL the boundaries of possible SAINT-GOBAIN

Glossary of Materials • Rulon® AR Saint-Gobain is a worldwide group whose history spans more than three centuries. Created in 1665 in France, Saint-Gobain launched its first industrial department with the production of mirrors, which adorn the famous Hall of Mirrors at Versailles. Expansion beyond French borders began in the middle of the 19th century. An international pioneer, Saint-Gobain established a glass factory in Germany in 1857, another in Italy in 1889 and one in Belgium in 1904. The group moved toward the New World in 1937 with the opening of a plant in Brazil. Strongly established...

The list above is only a partial list of available formulations of Rulon® P or V data may be exceeded based on specific application requirements. Ask to speak to an Application Engineer. RATINGS above are relative within Rulon® family ONLY. For Rulon® materials, coefficient of friction decreases with increasing load, and wear decreases with increasing surface hardness. For PTFE based materials, wear in steam and wet environments is higher than in dry environments. Omniseal Solutions™ offers enhanced Rulon® grades, which minimize this effect. Most Rulon® products have excellent chemical compatability....

Rulon® AR is a light maroon colored material best known as the current version of the first Rulon® introduced, namely Rulon® A. It 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 reliabiltiy 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® LR 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® LR 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. Products...

Rulon® J is an all-polymeric reinforced, dull gold colored PTFE compound that operates exceptionally well against soft mating surfaces such as 316 stainless steel, aluminum, mild steel, brass and other plastics. The unique "shaft friendly" material is also low in friction and wear and self-lubricating. Rulon® J has one of the lowest coefficients of friction of most reinforced PTFE materials. This makes it ideally suited for start/stop applications where stick-slip must be eliminated. The tribological properties of this material also make it suitable for both bearing and wear component applications....

RULON® 641 Rulon® 641 is manufactured from FDA and USDA compliant materials possessing excellent load and wear characteristics while meeting the requirements for USP Class VI. It 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 (6.9 MPa) at room temperature, deformation is a function of wall thickness, temperature and load. Its compatibility with a wide array of mating surfaces, including mild steel, 303 and 316 stainless steels, as well as harder materials, make it a...

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. It 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. Temperature - Typical Range °F (°C) Maximum...

RULON® 123 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. This material has a maximum operating temperature of 550°F (288°C). Rulon® 123 releases black wear debris over time and should not be used in ultra-dry, vacuum applications, or where electrical insulation...
