Material Notes:
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-HFInjection Notes: Minimum drying conditions: 3 hours at 350°F, 4 hours at 300°F, or 16 hours at 250°F. Compression Ratio: 1:1 to 1.5:1 Begin hold pressure at 6000-8000 psi for several seconds, then drop off to 3000-5000 psi for the duration of the hold pressure sequence. Molded parts must be post cured.Information provided by Solvay Specialty Polymers.
