Working with PC-FR ESD-FR
Is PC-FR easy to machine?
Machines cleanly with sharp positive-rake carbide tools, high speed / light feed and air cooling; avoid water-soluble coolants and anneal 120 °C to prevent stress cracking around holes.
Can PC-FR be welded?
Ultrasonic, hot-plate, laser and IR welding all work; solvent bonding with dichloromethane blends or UV/cyanoacrylate adhesives — never use ammonia- or amine-based cleaners.
Can PC-FR be formed, bent or molded?
Dry 4 h at 120 °C (<0.02% moisture), melt 270–305 °C, mold 70–110 °C, generous radii and 0.5–1.5° draft; for FDM print at 265–305 °C nozzle with 100–130 °C chamber/bed, PVP/PC-adhesive plate and enclosure to stop warping.
What surface finishes work on PC-FR?
Paints and hard-coats adhere well after IPA wipe (no aggressive solvents); vacuum metallizing and EMI conductive coatings common; polishing or vapor smoothing is limited — better to mold/print a gloss surface.

PC-FR ESD-FR — frequently asked
What is PC-FR ESD-FR used for?
PC-FR ESD-FR is typically used for aircraft interiors, rail components and electrical housings. In short: flame-retardant PC (V-0 class).
What is the yield strength of PC-FR ESD-FR?
PC-FR ESD-FR has a typical yield strength of 57 MPa (8.27 ksi) and a tensile strength of 58 MPa (8.41 ksi) — stronger than 63% of polymer grades. Strength varies by condition: see the 11 listed tempers.
Is PC-FR ESD-FR easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 73% of polymer grades). Machines cleanly with sharp positive-rake carbide tools, high speed / light feed and air cooling; avoid water-soluble coolants and anneal 120 °C to prevent stress cracking around holes.
Can PC-FR ESD-FR be welded?
With care — weldability is rated fair (50/100). Ultrasonic, hot-plate, laser and IR welding all work; solvent bonding with dichloromethane blends or UV/cyanoacrylate adhesives — never use ammonia- or amine-based cleaners.
What surface finishes work on PC-FR ESD-FR?
Paints and hard-coats adhere well after IPA wipe (no aggressive solvents); vacuum metallizing and EMI conductive coatings common; polishing or vapor smoothing is limited — better to mold/print a gloss surface.
Can PC-FR ESD-FR be formed, bent or molded?

What is the maximum service temperature of PC-FR ESD-FR?
PC-FR ESD-FR is rated for continuous use to about 120°C (248 °F), and briefly to 140°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between PC-FR V0 and PC-FR IM-FR?
V0 is the default condition — default choice for electrical enclosures and housings needing V-0 with full PC toughness. IM-FR: choose for thick-wall or cold-service FR parts needing ductile failure down to −30 °C and below. Yield strength is 62 MPa in V0 versus 56 MPa in IM-FR.
