Working with PBI TF-60V
Is PBI easy to machine?
Machine like a hard, brittle ceramic-filled plastic: sharp polished carbide (or PCD for filled grades), high speed, light feeds, minimal heat, generous corner radii; parts are notch-sensitive and stock should be kept dry/annealed to control post-machining growth.
Can PBI be welded?
Not weldable or heat-staked — PBI does not melt; join by fasteners, press fit, adhesives (epoxy after abrasion/primer) or mechanical clamping.
Can PBI be formed, bent or molded?
Not melt-processable: shapes are produced by high-temperature/high-pressure sinter (compression) molding of resin powder, then finish-machined; no injection molding, extrusion or thermoforming.
What surface finishes work on PBI?
No plating or anodizing; typical finishing is fine machining/lapping, light bead-blast or vapor-honing, and thorough drying/annealing cycles before dimensional inspection — natural color is dark bronze-brown to black.

PBI TF-60V — frequently asked
What is PBI TF-60V used for?
PBI TF-60V is typically used for semiconductor test sockets, wafer-handling parts, hot-gas and valve seats, insulator bushings, seals and back-up rings and cryogenic-to-high-temperature structural insulators. In short: highest temperature plastic.
What is the tensile strength of PBI TF-60V?
PBI TF-60V has a typical tensile strength of 100 MPa (14.5 ksi) — stronger than 89% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is PBI TF-60V easy to machine?
Reasonably — machinability is rated good (58/100, worse than 55% of polymer grades). Machine like a hard, brittle ceramic-filled plastic: sharp polished carbide (or PCD for filled grades), high speed, light feeds, minimal heat, generous corner radii; parts are notch-sensitive and stock should be kept dry/annealed to control post-machining growth.
Can PBI TF-60V be welded?
Not readily — weldability is rated not recommended (8/100). Not weldable or heat-staked — PBI does not melt; join by fasteners, press fit, adhesives (epoxy after abrasion/primer) or mechanical clamping.
What surface finishes work on PBI TF-60V?
No plating or anodizing; typical finishing is fine machining/lapping, light bead-blast or vapor-honing, and thorough drying/annealing cycles before dimensional inspection — natural color is dark bronze-brown to black.
Can PBI TF-60V be formed, bent or molded?
Not melt-processable: shapes are produced by high-temperature/high-pressure sinter (compression) molding of resin powder, then finish-machined; no injection molding, extrusion or thermoforming.
What is the maximum service temperature of PBI TF-60V?
PBI TF-60V is rated for continuous use to about 260°C (500 °F), and briefly to 500°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
Can FabDigit make parts in PBI TF-60V?
Yes — PBI TF-60V is available for CNC machining, sheet metal and injection molding; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
