Solvay Specialty Polymers Torlon® 4601 Polyamide-imide (PAI)  (Unverified Data**)

Torlon 4601 is a specialty wear-resistant grade of polyamide-imide (PAI). Most Torlon PAI grades cannot be molded successfully in molds with undercuts. Torlon 4601 has been formulated to be moldable in tools with minor undercuts and give very good performance 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 4601 polyamide-imide include ball bearing cages and other molded articles that require undercut tooling.Injection Notes: Minimum drying times are: 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 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 cured.Information provided by Solvay Specialty Polymers.
