| Good wear resistance at high velocities and high pressures, contains PTFE and graphite Torlon® 4435 is a polyamide-imide resin specifically designed to provide exceptionally low wear performance in non-lubricated applications even at high pressure and velocity (PV) conditions. Not only is Torlon® 4435 particularly suited to applications where lubrication is impossible or undesirable, it provides an additional margin of safety for lubricated systems in the event that lubrication is lost. The impressive flexural and compressive stiffness from cryogenic to elevated temperatures allows it to be used for demanding load-bearing applications. The low coefficient of thermal expansion provides the ability to meet close tolerances over a wide temperature range. Due to its electrically dissipative property, this grade may also be considered for anti-static functions. Specific applications where Torlon® 4435 may be used are thrust washers, seal rings, sliding vanes, bobbins, bushings, clutch rollers and pistons. The resin can be injection molded into complex shapes. - High flow: Torlon® 4435-HF Applications: Aerospace Applications; Aircraft Applications; Automotive Applications; Bearings; Bushings; Cams; Gears; Industrial Applications; Industrial Parts; Machine/Mechanical Parts; Metal Replacement; Rollers; Sealing Devices; Seals; Thrust Washer; Transmission Applications; Washer Features: Chemical Resistant; Creep Resistant; Flame Retardant; High Heat Resistance; High Temperature Strength; Low Friction; Self Lubricating; Semi Conductive; Wear Resistant Injection notes: Minimum drying conditions: 3 hours at 350°F, 4 hours at 300°F, or 16 hours at 250°F.
