| Excellent wear resistance in lubricated environments, contains PTFE and carbon fiber Torlon® 4645, an injection-moldable, wear-resistant grade of polyamide-imide (PAI), has been formulated to give outstanding wear resistance in lubricated wear applications. Torlon® PAI has the highest strength and stiffness of any thermoplastic up to 275°C (525°F). It has outstanding resistance to wear, creep and chemicals. Potential applications for Torlon® 4645 polyamide-imide include thrust washers, seal rings, sliding vanes, bobbins, bushings, clutch rollers and pistons. Markets/Uses: Automotive / Drivetrain / Lubricated; Automotive / Drivetrain / Needle Bearing Replacement Rings; Automotive / Drivetrain / Seal Rings; Automotive / Drivetrain / Thrust Bearings; Automotive / Drivetrain / Thrust Washers; Wear-Resistant Plastics / High Temperature Friction & Wear / Lubricated Applications: Automotive Applications; Bearings; Bobbins; Bushings; Seals; Thrust Washer Features: Chemical Resistant; Creep Resistant; Flame Retardant; High Heat Resistance; High Stiffness; High Temperature Strength; Low Friction; Self Lubricating; Semi Conductive; Wear Resistant Injection notes: Minimum drying times are: 3 hours at 350°F (177°C), 4 hours at 300°F (149°C), or 16 hours at 250°F (121°C).
Compression Ratio between 1:1 and 1.5:1
Begin hold pressure at a high setting 6,000-8,000 psi (41.37-55.16 MPa), for several seconds, then drop off to 3,000-5,000 psi (20.69-34.48 MPa), for the duration of the hold pressure sequence.
Molded parts must be post cured. Information provided by Solvay Specialty Polymers. |
