Rod PTFE Rulon® AR

sheettubeaeronautical

Overview
Rulon® AR is a light maroon, engineered ceramic-filled PTFE designed as the modern version of the original Rulon® A. It offers greater flexibility than Rulon® LR and is intended for seals, bonded coatings and slide surfaces where improved physical properties are required. The material is chemically inert and suitable for extended non-lubricated service.

Key properties

• Filled PTFE: engineered ceramic filler, light maroon color
• High compressive strength
• Low coefficient of friction
• Chemical resistance and electrical insulation
• Excellent abrasion and corrosion resistance in dry service
• Capable of operating at high PV values (see performance)

Performance data & features

• Friction coefficient: 0.15–0.25
• Max PV (dry/lub): 0.35 MPa·m/s (table entry)
• Capable of operating at PV values up to approximately 10,000 (intermittent higher PV possible, as noted)
• Superior dry friction behavior and reduction of stick/slip
• Reduced hardware abrasion
• Minimal moisture absorption and stable dimensions in aggressive chemicals
