ERTACETAL – VERSATILE, FUNCTIONAL AND RELIABLE

Ertacetal is one of the most widely used and most versatile of the Dotmar engineering plastics.

It has seen such widespread and varied use in so many industries for very good reason.

Almost every machine builder and manufacturer has at some time called and asked for information on “that hard white plastic” .

Ertacetal Properties can best be characterized as follows:

  • High hardness and stiffness
  • It is strong with good mechanical properties
  • Good chemical resistance
  • Good electrical insulating properties
  • Excellent creep resistance and dimensional stabilitY
  • Excellent bearing material:
    • low coefficient of friction
    • low stick / slip characteristic
  • Good wear properties - both wet and dry condition
  • Natural Ertacetal is FDA compliant for direct food contact
  • Excellent machinability

Uses of Ertacetal:
bearings, bushings, gears, wear pads, rollers, components.

It shows up in virtually every type of industrial machinery including food processing equipment, packaging machinery, and analytical equipment. It’s also widely used by the chemical processing and water processing industries for valves, seals, fittings and manifolds since it has better chemical and corrosion resistance than many metals.

Ertacetal Compared to Other Engineering Plastics:
Many engineering plastics are known for a single special property. The appeal of Ertacetal is that it offers a good balance of properties. The comparison in the table highlights some of Ertacetal’s features.
ERTACETAL COMPARED TO OTHER MECHANICAL PLASTICS
Ertacetal vs. UHMW-PE
• Advantages:
1 Ertacetal is stronger and stiffer than UHMW PE, particularly at elevated temperatures.
2 It is easier to machine to tight tolerances since the coefficient of thermal expansion is half of UHMW-PE.
• Disadvantages:
It lacks the impact resistance of UHMW.
Ertacetal vs. Cast Nylon
• Advantages:
1. Ertacetal is 2-3 times tougher than cast nylon so it may be a better choice for applications where parts will experience impact.
2. Ertacetal also has better wear resistance than nylon in wet bearing applications.
• Disadvantages:
Ertacetal bearings will wear out faster than nylon in dry bearing environments.
Ertacetal vs. (PET) Polyester
• Advantages:
Ertacetal is tougher than PET and is less expensive.
• Disadvantages:
PET can operate at higher temperatures than acetal, and it has better dimensional stability and chemical resistance than Ertacetal.
