What is PC-ABS FR?
PC-ABS FR is PC-ABS in the FR grade — pick for electrical enclosures, chargers and appliance parts needing UL 94 V-1/V-0 with only modest loss of toughness. PC-ABS FR has a yield strength of 55 MPa (7.98 ksi) and a tensile strength of 57 MPa (8.27 ksi) — stronger than 62% of polymer grades. Elongation at break is 65% and the elastic modulus is 2.4 GPa (0.348 Msi). PC-ABS FR has a density of 1.2 g/cm³ (0.0434 lb/in³), heavier than 57% of polymer grades. Its glass-transition temperature is 125°C (257 °F).
Advantages
- Tough — resists crack growth — 3.5 MPa·√m (3.19 ksi·√in), better than 81% of polymer grades
- Readily welded — 72/100, better than 80% of polymer grades

Working with PC-ABS FR
Is PC-ABS easy to machine?
Machines and drills easily with sharp, high-rake tools and air/mist cooling; avoid heat build-up and use light finishing passes to prevent stress crazing at edges.
Can PC-ABS be welded?
Ultrasonic, hot-plate, spin and laser welding all work well; solvent bonding with methylene-chloride/MEK cements and cyanoacrylate/epoxy adhesives is common.
Can PC-ABS be formed, bent or molded?
Dry 2–4 h at 80–100 °C before moulding; melt 240–285 °C, mould 60–95 °C, shrinkage 0.4–0.7 %; keep gates/wall transitions generous to limit moulded-in stress and use ≥0.5° draft.
What surface finishes work on PC-ABS?
Excellent paint, pad-print and vacuum-metallizing substrate; ABS phase allows electroless-nickel/chrome plating — anneal or use plating grades to prevent solvent-induced cracking.

PC-ABS FR — frequently asked
What is PC-ABS FR used for?
PC-ABS FR is typically used for automotive interior trim and consoles, electrical enclosures, IT and appliance housings, power tool housings, plated decorative trim and medical device housings. In short: impact resistant blend.
What is the yield strength of PC-ABS FR?
PC-ABS FR has a typical yield strength of 55 MPa (7.98 ksi) and a tensile strength of 57 MPa (8.27 ksi) — stronger than 62% of polymer grades. Strength varies by condition: see the 5 listed tempers.
Is PC-ABS FR easy to machine?
Reasonably — machinability is rated good (65/100, better than 66% of polymer grades). Machines and drills easily with sharp, high-rake tools and air/mist cooling; avoid heat build-up and use light finishing passes to prevent stress crazing at edges.
Can PC-ABS FR be welded?
Yes — weldability is rated very good (72/100). Ultrasonic, hot-plate, spin and laser welding all work well; solvent bonding with methylene-chloride/MEK cements and cyanoacrylate/epoxy adhesives is common.
What surface finishes work on PC-ABS FR?
Excellent paint, pad-print and vacuum-metallizing substrate; ABS phase allows electroless-nickel/chrome plating — anneal or use plating grades to prevent solvent-induced cracking.
