Working with Torlon 7130 PC

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 PC — frequently asked

What is Torlon 7130 PC used for?

Torlon 7130 PC 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 PC?

Torlon 7130 PC has a typical tensile strength of 203 MPa (29.4 ksi) — stronger than 99% of polymer grades. Strength varies by condition: see the 2 listed tempers.

Is Torlon 7130 PC easy to machine?

Reasonably — machinability is rated fair (45/100, worse than 78% 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 PC 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 PC?

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 PC 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 PC?

Torlon 7130 PC is rated for continuous use to about 250°C (482 °F), and briefly to 280°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
