Furon has over forty years of intensive research and development behind its RULON formulations. This has led to the RULON family of specially-compounded forms of PTFE fluoropolymer and other inert ingredients. Hundreds of materials were tried along with variations in blending techniques, molding pressures, temperatures, etc., until the ideal RuLON formulas were developed.
RULON AR was introduced to industry in 1952, as a plastic bearing material with low coefficient of friction, excellent abrasion resistance and extreme resistance to corrosion. It immediately found a great number of applications as a bearing material because it required no lubrication and was capable of performing under severe temperature (-400° to +550°F.) and corrosive conditions. RuLON AR has a 1,000-fold increase in wear resistance over PTFE, lower deformation under load, greater stiffness and higher compressive strength.
Today RULON is widely used for electrical, mechanical and chemical applications in industry
Since the advent of RULON AR, Furon has developed a number of other RuLON formulations for special uses RULON J. F and LR, etc. These formulations are listed on page 3, indicating their best particular fields of use.
RuLON materials are available in numerous standard forms such as extruded rod, tubing, skived tape, molded rods and tubes, sheets and shapes molded to specifications. They are readily machinable in a manner similar to PTFE and may be surface-treated for bonding.
In addition to RULON compounds, which are the most widely used formulations, Furon has compounded PTFE fluoropolymer with many other additives such as fiberglass, quartz, mica, carbon, graphite, ceramic fiber, etc. These and other agents have been added to develop specified properties to meet special customer requirements.
