ABS-ESD
Properties of the ESD condition, compared with the other ABS grades.
Carbon- or additive-modified ABS for electronics trays, tote boxes and housings needing 10⁴–10⁹ Ω surface resistivity.
What is ABS-ESD?
ABS-ESD is ABS in the ESD grade — carbon- or additive-modified ABS for electronics trays, tote boxes and housings needing 10⁴–10⁹ Ω surface resistivity. ABS-ESD has a yield strength of 42 MPa (6.09 ksi) and a tensile strength of 40 MPa (5.8 ksi) — weaker than 65% of polymer grades. Elongation at break is 8% and the elastic modulus is 2.6 GPa (0.377 Msi). ABS-ESD has a density of 1.08 g/cm³ (0.039 lb/in³), lighter than 66% of polymer grades. Its glass-transition temperature is 105°C (221 °F). Unfilled is the default condition FabDigit quotes; ESD is available on request or by drawing note.

Working with ABS-ESD
Is ABS easy to machine?
Machines easily with sharp, positive-rake, polished-flute tools and high speed/low feed; use air blast rather than flood coolant and avoid solvent-based cutting fluids that cause stress cracking.
Can ABS be welded?
Excellent solvent bonding (MEK, acetone, ABS cement) plus ultrasonic, vibration, hot-plate and hot-gas welding; anneal or de-stress before solvent exposure to prevent crazing.
Can ABS be formed, bent or molded?
Dry 2–4 h at 80 °C, mould at 210–260 °C melt / 40–80 °C tool with 0.4–0.7 % shrinkage; extruded sheet vacuum-forms readily at 150–180 °C.
What surface finishes work on ABS?
Takes paint, hot stamping, vapour smoothing (acetone) and is the standard plastic for decorative chrome electroplating after chromic/permanganate etch; requires UV-stable topcoat for outdoor use.
ABS 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.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| styrenerigid SAN matrix component | 40 – 60 | 50 |
| acrylonitrileprovides chemical resistance and strength | 15 – 35 | 24 |
| polybutadiene rubbergrafted rubber phase; higher levels = high-impact grades | 5 – 30 | 18 |
| additives (stabilisers, lubricants, pigm | 0.5 – 3 | 1.5 |
ABS-ESD — frequently asked
What is ABS-ESD used for?
ABS-ESD is typically used for electronic enclosures and housings, power tool housings, computer keyboards, automotive interior trim, appliance panels and bezels and thermoformed trays and luggage shells. In short: tough general purpose.
What is the yield strength of ABS-ESD?
ABS-ESD has a typical yield strength of 42 MPa (6.09 ksi) and a tensile strength of 40 MPa (5.8 ksi) — weaker than 65% of polymer grades. Strength varies by condition: see the 18 listed tempers.
Is ABS-ESD easy to machine?
Yes — machinability is rated very good (80/100, better than 83% of polymer grades). Machines easily with sharp, positive-rake, polished-flute tools and high speed/low feed; use air blast rather than flood coolant and avoid solvent-based cutting fluids that cause stress cracking.
Can ABS-ESD be welded?
Yes — weldability is rated very good (78/100). Excellent solvent bonding (MEK, acetone, ABS cement) plus ultrasonic, vibration, hot-plate and hot-gas welding; anneal or de-stress before solvent exposure to prevent crazing.
What surface finishes work on ABS-ESD?

What is the maximum service temperature of ABS-ESD?
ABS-ESD is rated for continuous use to about 75°C (167 °F), and briefly to 95°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ABS Unfilled and ABS Tough?
Unfilled is the default condition — default balanced grade for housings, trim and enclosures where impact, appearance and cost matter more than heat or stiffness. Tough: vat-photopolymer resin marketed as ABS-like for snap fits, prototypes and functional assemblies; tough and ductile but far lower heat resistance and UV-ageing than moulded ABS. Yield strength is 42 MPa in Unfilled versus 38 MPa in Tough.
