What is Torlon 7130 AM?
Torlon 7130 AM is Torlon 7130 in the AM condition — condition straight out of the mold; use only for fit checks or before the cure cycle — strength, creep and solvent resistance are well below rated values. Torlon 7130 AM has a tensile strength of 155 MPa (22.5 ksi), stronger than 96% of polymer grades. Elongation at break is 5% and the elastic modulus is 21.5 GPa (3.12 Msi). Torlon 7130 AM has a density of 1.48 g/cm³ (0.0535 lb/in³), heavier than 87% of polymer grades. Its glass-transition temperature is 275°C (527 °F). PC is the default condition FabDigit quotes; AM is available on request or by drawing note.

Working with Torlon 7130 AM
Is Torlon 7130 easy to machine?
Machine fully post-cured stock with sharp PCD or fine-grain carbide, high speed and light feeds; carbon fiber is very abrasive and dry cutting or air/mist cooling avoids moisture pickup before final cure.
Can Torlon 7130 be welded?
Not melt-weldable in practice; join by epoxy or PAI-compatible adhesive, threaded inserts or mechanical fasteners with generous bosses.
Can Torlon 7130 be formed, bent or molded?
Injection mold at 335–360 °C melt / 200–230 °C mold with dried resin (<0.05 % moisture), then run the multi-day staged post-cure to ~260 °C to develop rated properties.
What surface finishes work on Torlon 7130?
Parts are self-colored dark grey/black; no plating or anodizing — surfaces are typically left as-machined, lightly bead-blasted or lapped for seal faces.
Torlon 7130 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

Torlon 7130 AM — frequently asked
What is Torlon 7130 AM used for?
Torlon 7130 AM is typically used for non-lubricated bearings, valve seats, aerospace seal rings and piston rings in compressors. In short: stiffest Torlon grade; runs without external lubrication; 203 MPa tensile strength.
What is the tensile strength of Torlon 7130 AM?
Torlon 7130 AM has a typical tensile strength of 155 MPa (22.5 ksi) — stronger than 96% of polymer grades. Strength varies by condition: see the 2 listed tempers.
Is Torlon 7130 AM easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 73% of polymer grades). Machine fully post-cured stock with sharp PCD or fine-grain carbide, high speed and light feeds; carbon fiber is very abrasive and dry cutting or air/mist cooling avoids moisture pickup before final cure.
Can Torlon 7130 AM be welded?
Not readily — weldability is rated not recommended (5/100). Not melt-weldable in practice; join by epoxy or PAI-compatible adhesive, threaded inserts or mechanical fasteners with generous bosses.
What surface finishes work on Torlon 7130 AM?
Parts are self-colored dark grey/black; no plating or anodizing — surfaces are typically left as-machined, lightly bead-blasted or lapped for seal faces.
Can Torlon 7130 AM be formed, bent or molded?
Injection mold at 335–360 °C melt / 200–230 °C mold with dried resin (<0.05 % moisture), then run the multi-day staged post-cure to ~260 °C to develop rated properties.
What is the maximum service temperature of Torlon 7130 AM?
Torlon 7130 AM is rated for continuous use to about 180°C (356 °F), and briefly to 280°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
