Engineering Plastics - Acetal

Dotmar offers both homopolymer and copolymer grades of acetal. Ertacetal C (Acetron GP) is porosity-free and offered as our standard general purpose grade. For slightly higher mechanical properties, we offer as a non-standard, homopolymer Ertacetal H (Acetal) (Derlin) products.

Ertacetal H (Derlin), homopolymer acetal offers slightly higher mechanical properties than Ertacetal C Acetal, but may contain a low-density centre, especially in larger cross-sections. Ertacetal C (Copolymer) also offers better chemical resistance than homopolymer acetal. Ertacetal H is suitable for small diameter, thin-walled bushings that benefit from the additional strength and rigidity of homopolymer acetal.

It is the preferred acetal for food contact and medical applications. Ertacetal,(Dotmar's trade name for acetal rod, acetal sheet & acetal tube) is a semi-crystalline material with high strength, a low coefficient of friction and good wear properties especially in wet environments (resistance to hydrolysis).

Advantages of Acetal Rod, Acetal Sheet & Acetal Tube:

Acetal's great machinability together with its dimensional stability, mechanical strength, zero moisture absorption and good load-bearing properties make it ideal for close-tolerance parts.

Key Features of Acetal Rod, Acetal Sheet & Acetal Tube

  • High hardness and stiffness
  • Very high mechanical properties
  • Excellent creep resistance and dimensional stability
  • Excellent dielectrical properties
  • Low co-efficient of friction

Applications of Acetal: Acetal Machined Parts:

  • Precision gears
  • Bearings with close tolerances
  • Electrical engineering insulators
  • Compact bearing assembly
  • Snap fit assemblies
  • Parts which operate in water between 60 to 90;C

Distribution : Acetal Products

  • Available in Acetal Rod, Acetal Sheet, Acetal Tube, Machined Parts.
