Compare all 9 grades and fillsHide
| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
Unfilled natural, conditioned | Property set after moisture equilibration in normal air — use this for parts in ambient/humid service; stiffness drops less than for PA6/PA66 because PA610 absorbs about half the water. | 42 | 44 | 220 | 74 Shore D |
Impact-modified | Elastomer-toughened compound for snap-fits, cold-impact and vibration-loaded parts where notch sensitivity matters more than stiffness. | 45 | 250 | 70 Shore D | |
Internally lubricated bearing grade | Lower friction and wear for unlubricated bushings, slides, gears and cams; MoS₂ types also act as nucleants improving crystallinity and stiffness. | 54 | 55 | 40 | 80 Shore D |
UV-stabilized / carbon-black weatherable | Carbon-black + HALS package for outdoor tubing, cable jacketing, brush bristles and agricultural parts. | 55 | 57 | 110 | 79 Shore D |
High-viscosity extrusion / monofilament grade | High-molecular-weight resin with melt strength for brush bristles, fishing line, tubing and cable sheathing; drawn filaments reach far higher tensile than moulded bars. | 55 | 60 | 200 | 78 Shore D |
Heat-stabilized | Copper-halide or phenolic/amine stabilized compound for long-term hot-air service (under-hood, motor and appliance parts). | 56 | 58 | 110 | 79 Shore D |
UF-DAMDefault Unfilled natural, dry-as-moulded | Baseline injection/extrusion resin as measured immediately after moulding — use for design in dry service (fuel, oil, sealed assemblies). | 58 | 60 | 120 | 78 Shore D |
15 % glass-fiber reinforced | Moderate stiffness/creep upgrade while keeping useful toughness and low warpage — gears, housings, clips. | 100 | 6 | 85 HRM | |
30–33 % glass-fiber reinforced | Main structural grade: high stiffness, strength and HDT with much reduced moisture-driven dimensional change — load-bearing brackets, gears, pump and fuel-system parts. | 140 | 3 | 92 HRM |
What is PA610?
PA610 (Zytel 71G) is a partially bio-based polyamide polymerized from hexamethylenediamine and sebacic acid, available unfilled (dry-as-moulded or conditioned), with 15–30% glass, heat-stabilized, UV-black, lubricated and high-viscosity extrusion grades. It absorbs less moisture and holds dimensions better than PA6/PA66, and at 1.08 g/cm3, 60 MPa tensile, 58 MPa yield, 120% elongation and 2.2 GPa modulus it suits extruded monofilament, tubing and injection-moulded parts. Continuous service is limited to about 95 °C with Tg near 50 °C, and the low-energy surface needs pretreatment for paint or adhesive. Availability is narrower than PA66; PA612 is the closest substitute. PA610 has a density of 1.08 g/cm³ (0.039 lb/in³), lighter than 67% of polymer grades. Its glass-transition temperature is 50°C (122 °F). PA610 has a yield strength of 58 MPa (8.41 ksi) and a tensile strength of 60 MPa (8.7 ksi) — stronger than 66% of polymer grades. Elongation at break is 120% and the elastic modulus is 2.2 GPa (0.319 Msi).

Working with PA610
Is PA610 easy to machine?
Machines like other cast/extruded nylons — sharp positive-rake tools, high speed, low feed, air or mist cooling; stress-relieve and allow for post-machining moisture pickup on precision parts.
Can PA610 be welded?
Joins well by hot-plate, vibration, ultrasonic, spin and hot-gas welding; adhesive bonding needs plasma/primer pretreatment because of low surface energy.
Can PA610 be formed, bent or molded?
Dry pellets to <0.10 % moisture (80 °C, 4–6 h desiccant), melt 240–275 °C, mold 50–100 °C; use warm molds and generous gates for gears to control the 1.0–2.0 % shrinkage and post-mold shrink.
PA610 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.

PA610 — frequently asked
What is PA610 used for?
PA610 is typically used for brush bristles, flexible tubing, electrical insulation and cosmetic packaging components. In short: partially bio-based polyamide; low moisture uptake; stable alternative to PA66.
What is the yield strength of PA610?
PA610 has a typical yield strength of 58 MPa (8.41 ksi) and a tensile strength of 60 MPa (8.7 ksi) — stronger than 66% of polymer grades. Strength varies by condition: see the 9 listed tempers.
Is PA610 easy to machine?
Yes — machinability is rated very good (72/100, better than 76% of polymer grades). Machines like other cast/extruded nylons — sharp positive-rake tools, high speed, low feed, air or mist cooling; stress-relieve and allow for post-machining moisture pickup on precision parts.
Can PA610 be welded?

What is the maximum service temperature of PA610?
PA610 is rated for continuous use to about 95°C (203 °F), and briefly to 150°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between PA610 UF-DAM and PA610 UF-COND?
UF-DAM is the default condition — baseline injection/extrusion resin as measured immediately after moulding — use for design in dry service (fuel, oil, sealed assemblies). UF-COND: property set after moisture equilibration in normal air — use this for parts in ambient/humid service; stiffness drops less than for PA6/PA66 because PA610 absorbs about half the water. Yield strength is 58 MPa in UF-DAM versus 42 MPa in UF-COND.
