What is PA11 ESD?
PA11 ESD is PA11 in the ESD grade — for electronics handling trays, fuel-system components and fixtures requiring controlled surface resistivity. PA11 ESD has a yield strength of 38 MPa (5.51 ksi) and a tensile strength of 44 MPa (6.38 ksi) — weaker than 64% of polymer grades. Elongation at break is 15% and the elastic modulus is 2 GPa (0.29 Msi). PA11 ESD has a density of 1.06 g/cm³ (0.0383 lb/in³), lighter than 68% of polymer grades. Its glass-transition temperature is 46°C (115 °F).
Advantages
- Conducts heat well — 0.35 W/m·K (0.202 BTU/hr·ft·°F), better than 91% of polymer grades
- Good UV / weathering resistance — 55/100, better than 77% of polymer grades

Physical5
PA11 ESD has a density of 1.06 g/cm³ (0.0383 lb/in³), lighter than 68% of polymer grades. Its glass-transition temperature is 46°C (115 °F).
Mechanical13
PA11 ESD has a yield strength of 38 MPa (5.51 ksi) and a tensile strength of 44 MPa (6.38 ksi) — weaker than 64% of polymer grades. Elongation at break is 15% and the elastic modulus is 2 GPa (0.29 Msi).
Thermal11
PA11 ESD is rated for continuous service to 90°C (194 °F). It conducts heat at 0.35 W/m·K (0.202 BTU/hr·ft·°F), better than 91% of polymer grades. Thermal expansion is 120 µm/m·K (66.7 µin/in·°F).
Electrical6
PA11 ESD is an electrical insulator with a dielectric strength of 23 kV/mm (584.2 V/mil) and a resistivity of 1,000,000 Ω·m.
Chemical & Environmental3
Corrosion resistance is very good (84/100), better than 58% of polymer grades. UV resistance is good.
Sustainability3
Producing a kilogram of PA11 ESD takes about 75 MJ of energy and emits 5 kg of CO₂ — less than 91% of polymer grades. Typical recycled content is 40%.
Manufacturability6
PA11 ESD's machinability is good (60/100, better than 51% of polymer grades); weldability fair (50/100).
Values are nominal handbook figures for design screening. Confirm any required mill or lot documentation when quoting.
Working with PA11 ESD
Is PA11 easy to machine?
Machines cleanly with sharp, high-rake tools and air cooling; tough and slightly gummy, so use climb milling and avoid heat build-up that closes drilled holes.
Can PA11 be welded?
Hot-plate, hot-gas, ultrasonic and laser welding all work on PA11; solvent bonding is impractical — use cyanoacrylate or two-part polyurethane/epoxy after plasma or abrasive prep.
Can PA11 be formed, bent or molded?
Print with bed ~185–190 °C and slow, uniform cooling to limit curl; reuse powder at 30–70% refresh, dry powder before use, and scale parts ~2.5–3.5% for sinter shrinkage.
What surface finishes work on PA11?
Bead blasting, vibratory tumbling, chemical vapor smoothing and dyeing (black/colored) work well; PA11's low moisture pickup keeps dyed and painted parts dimensionally stable, but UV-stabilized topcoat is advised outdoors.
PA11 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.

PA11 ESD — frequently asked
What is PA11 ESD used for?
PA11 ESD is typically used for flexible fuel lines, pneumatic tubing, living hinges and snap-fit enclosures, footwear midsoles, automotive functional brackets and ducts and sports equipment components. In short: flexible; durable nylon.
What is the yield strength of PA11 ESD?
PA11 ESD has a typical yield strength of 38 MPa (5.51 ksi) and a tensile strength of 44 MPa (6.38 ksi) — weaker than 64% of polymer grades. Strength varies by condition: see the 17 listed tempers.
Is PA11 ESD easy to machine?
Reasonably — machinability is rated good (60/100, better than 51% of polymer grades). Machines cleanly with sharp, high-rake tools and air cooling; tough and slightly gummy, so use climb milling and avoid heat build-up that closes drilled holes.
Can PA11 ESD be welded?
With care — weldability is rated fair (50/100). Hot-plate, hot-gas, ultrasonic and laser welding all work on PA11; solvent bonding is impractical — use cyanoacrylate or two-part polyurethane/epoxy after plasma or abrasive prep.
What surface finishes work on PA11 ESD?
Bead blasting, vibratory tumbling, chemical vapor smoothing and dyeing (black/colored) work well; PA11's low moisture pickup keeps dyed and painted parts dimensionally stable, but UV-stabilized topcoat is advised outdoors.

Print with bed ~185–190 °C and slow, uniform cooling to limit curl; reuse powder at 30–70% refresh, dry powder before use, and scale parts ~2.5–3.5% for sinter shrinkage.
What is the maximum service temperature of PA11 ESD?
PA11 ESD is rated for continuous use to about 90°C (194 °F), and briefly to 130°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
