Working with PA610 UV-BK

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.

What surface finishes work on PA610?

Accepts acid dyeing, pad printing and laser marking; paint or plate only after flame/plasma or chemical etch pretreatment; can be polished but scratches easily.

PA610 UV-BK — frequently asked

What is PA610 UV-BK used for?

PA610 UV-BK 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 UV-BK?

PA610 UV-BK 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 9 listed tempers.

Is PA610 UV-BK easy to machine?

Yes — machinability is rated very good (76/100, better than 80% 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 UV-BK be welded?

Yes — weldability is rated very good (70/100). Joins well by hot-plate, vibration, ultrasonic, spin and hot-gas welding; adhesive bonding needs plasma/primer pretreatment because of low surface energy.

What surface finishes work on PA610 UV-BK?

Accepts acid dyeing, pad printing and laser marking; paint or plate only after flame/plasma or chemical etch pretreatment; can be polished but scratches easily.

Can PA610 UV-BK 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.

What is the maximum service temperature of PA610 UV-BK?

PA610 UV-BK 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.
