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, USDA, and NSF 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 (300℃).

Rulon?123 releases black wear debris over time and should not be used in ultra-dry, vacuum applications, or where electrical insulation is desired.

RULON W2

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 DWGV (European) certified for applications in contact with drinking water.

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.

RULON  641

Rulon?641 is manufactured from FDA compliant materials which possess excellent load and wear characteristics.

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 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 good choice for most food and pharmaceutical bearing applications.

RULON J

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  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 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.

How can we realize oil-free lubrication for compressor?

Many new materials are created with ideal oil-free lubrication materials along with the development of modern technology, such as PEEK and PTFE.

Good design and type selection. Proper materials and design could be selected based on the actual working conditions. The factors considered generally include pressure, temperature, media and motion speed.

Assembly quality is also a very import factor.

      Efforts must be made to avoid polluting gas by lubricating oil when compressing gas or avoid external gas from entering cylinder along with the development of modern industry. Therefore, the quality of oil-free lubricating compressor marks the level of compressor industry and also guarantees the quality of all kinds of production technologies. 

      The catalst of synthetic tower of synthesis ammonia plant may lead to a lower synthetic efficiency due to the oil contained in nitrogen-hydrogen gas. Therefore, the high-pressure oil-free lubricating nitrogen hydrogen compressor is urgently required.

The oxygen in air separation device may lead to combustion and explosion if it contains oil. Therefore, oil-free lubricating compressor is urgently required.

Oil-free lubricating compressor is also needed in deep cold works where the lubricating oil is frozen due to extremely low gas temperature.

The commonly used self-lubricating materials include: Polymer self-lubricating material PTFE, PEEK, PA, POM, PI and solid self-lubricating material: graphite, MoS2, BN and PbO.

Pure state materials are restrained in terms of application under different rigid working conditions, regardless of their performance. In order to overcome the restrictions, we carry out compound modification for these materials so as to improve the material performance on a targeted basis.

Materials formed by combining two or above substances with different chemical properties or tissues either in a micro or macro manner are called compound materials. The compound theory of compound material is under development. The compound theory of the materials, such as thermal performance and electric insulation is under exploration.

In consideration of multiple varieties and performances of these compound materials, we will provide clients with formula materials that can resolve client’s problems.
