Product features

DOCAMID 66 has higher strength and stiffness than DOCAMID 6 E. It also has better thermal and adhesion wear resistance.

Natural, Black

product family features

One of the longest established and most popular family of engineering plastics. It is extruded in smaller sizes and moulded in larger sizes. Thanks to the latter process, it is also produced in larger blocks and diameters than any other engineering plastic. It is available in sheet, rod, tube, slab and even other formats.

Previously marketed under brand names such as Danamid, Metamid and Bonamid, it is also known as nylon. Extruded polyamide 6 is also referred to as PA6 E and PA6 MO, and cast is also referred to as PA 6G, PA6G PA6 C or simply cast nylon. Cast polyamide is also unique in its wide range of colours, with blue, red, green, yellow and grey available in addition to natural and black base colours.

The most common type is polyamide 6 (PA6, PA 6). Polyamide 66 (PA66, PA 66, PA6.6 or PA 6.6) is in demand for its higher strength, while polyamide 12 (PA12, PA 12), now available in a smaller range of sizes, is used for its low moisture absorption.

Among its reinforced grades, the most notable are PA66 (PA66 GF30) and PA6 (PA6 GF30), both in glass fibre, and it is also available in flame retardant (Docamid 6 FR), carbon fibre (Docamid 66 CF20), oil filled, ELS (electrically conductive) and ESD (antistatic).

DOCAMIDE 66

Some important features

  • High strength (yield strength, tensile strength and compressive strength around 70-110 MPa)
  • Excellent toughness, no breakage (grooved Charpy: 12 kJ/m2)
  • Good slip properties (dry slip on smoothed and ground steel: m = 0.15-0.5),
  • Wide application temperature range: -50°C/+140°C (for short term use)
  • High hardness (Rockwell: M 85 - M 98)
  • Good fatigue strength and damping capacity
  • Good wear resistance
  • Favourable creep resistance (18 - 26 MPa tension for 1% elongation over 1000 hours)
  • Relatively high moisture absorption: in humid environments, precision parts need to take into account the resulting dimensional variation and changing material properties when calculating load capacity. When soaked with moisture, the material can become even tougher.

Main areas of application

Bearing bushes, guide and wear plates, support, tensioning, guide and conveyor rollers, rope pulleys, pulley sheaves, gears, racks, pulley wheels, sprockets, sprockets, hammer heads, cutting plates, pullers, insulators, sealing rings, etc.

Machining technology

  • Chipping (turning, milling, drilling, boring, reaming, sawing): conventional metal, in some cases woodworking tools - carbon steel, high speed steel, carbide, diamond - can be used with a sharp finish.
  • Cooling is recommended to allow high cutting speeds e.g. v = 100-500 m/min for turning and milling, v = 50-100 m/min for drilling.
  • Gluing and welding: feasible (with appropriate surface preparation)

Available formats

  • PA 66 rod
  • PA 66 plate
