Nylon

(PA, polyamide, Nycast®, Nycast®Nyoil, TCAST™, Nylatech®, Zytel®, Tecamid™, Sustamid®, ZL ®250 , Nylon 101, Nylatron®, Nylatron® GSM, and Nylatron® NSM)

Key Features:

  • Good mechanical strength
  • High impact strength, toughness
  • Good fatigue resistance
  • Lightweight
  • Very good wear properties
  • High mechanical dampening ability

Applications:

Gears, cams, bushings, slides, valves, pumps, wear pads, cable sheaves, seal rings, track plates, hammer heads, electrical insulators

Fabrication:

Nylon can be easily machined. Also stamped and die-cut. Lasering can be done with CO2 lasers. Can be difficult to weld and glue.

Standard Colors:

Natural (light yellow), Black

Standard Grades:

Nylon 6 and Nylon 6/6 are used interchangeably in a number of applications, but they do have slightly different characteristics that can be critical in some applications.

Nylon Type 6/6 Extruded:

More crystalline than Nylon 6. Has a higher melting point and higher heat deflection temperature than Nylon 6. Also has a higher stiffness, tensile modulus and flexural modulus than Nylon 6. Better chemical resistance to acids. More expensive than Nylon 6, especially in ½” and thicker sheet and 2” diameter and larger rod and tube.

Specifications met:

  • Nylon 6/6 resin meets ASTM D6779 PA0114 or ASTM D6779 PA0110B54420 and ASTM D4066 PA0110B544220 superseding ASTM D4066 PA0114 and old Federal Standard LP-410A compliance, Amendment 4 with exception to tensile strength, Tables I & V.
  • Stock shape specification ASTM D5989 S- PA0111
  • Nylon 6/6 natural resin meets FDA 177.1500, NSF, USDA, and DAIRY 3A requirements
  • Flammability – Nylon 6/6 meets UL94-V2 flammability.

Nylon 6 Cast:

Has higher impact and stress resistance than Nylon 6/6 and stands up to hydrocarbons better. Machines with less stress and fewer burrs.

Specifications met:

  • Resin meets LP-410 A
  • Stock shape specification ASTM D5989 S-PA0211
  • Natural meets FDA 177.1500, UL 94 HB flammability

Special Grades:

  • Nylon MD – (Molybdenum disulfide lubricant MoS2), lowers surface friction and increases surface hardness, strength and stiffness
  • Nylon Oil filled – oil filled grade lowers surface friction and hardness, increases impact resistance
  • Nylon 6/6 GF30 – 30 % glass filled has higher strength, stiffness and temperature resistance
  • Nylon 6 GF30 – 30 % glass filled nylon 6 improved resistance to abrasion, greater compression and flex strength. Nylon 6 glass filled also available in 10%, 20%, and 40% glass filled.
  • Hydlar Z – Aramid fiber (Kevlar R) filled Nylon: Kevlar fibers provide increased strength and temperature resistance and substantially improved wear resistance. No galling of mating wear surfaces.
  • Nylon 12 – Best moisture resistance of all the Nylons. Remains stable in humid environments. Very high toughness and good chemical resistance. Reduced sensitivity to stress cracking. Has the lowest melting point compared  to other Nylons  and a higher cost.
