ABS High Impact
Properties of the High Impact condition, compared with the other ABS grades.

What is ABS High Impact?
ABS High Impact is ABS in the High Impact grade — choose when notched impact and low-temperature toughness dominate (power-tool housings, luggage, protective covers); pays with lower stiffness and heat resistance. ABS High Impact has a yield strength of 36 MPa (5.22 ksi) and a tensile strength of 37 MPa (5.37 ksi) — weaker than 68% of polymer grades. Elongation at break is 40% and the elastic modulus is 1.9 GPa (0.276 Msi). ABS High Impact has a density of 1.04 g/cm³ (0.0376 lb/in³), lighter than 70% of polymer grades. Its glass-transition temperature is 105°C (221 °F). Unfilled is the default condition FabDigit quotes; High Impact is available on request or by drawing note.

Working with ABS High Impact
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 High Impact — frequently asked
What is ABS High Impact used for?
ABS High Impact 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 High Impact?
ABS High Impact has a typical yield strength of 36 MPa (5.22 ksi) and a tensile strength of 37 MPa (5.37 ksi) — weaker than 68% of polymer grades. Strength varies by condition: see the 18 listed tempers.
Is ABS High Impact 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 High Impact 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 High Impact?
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.
Can ABS High Impact be formed, bent or molded?

What is the maximum service temperature of ABS High Impact?
ABS High Impact 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 36 MPa in Unfilled versus 38 MPa in Tough.
