Thermoplastics

ACETAL SHEET & ROD

Acetal is a semi-crystaline engineering plastic manufactured by the polymerisation of formaldehyde.

It absorbs very little moisture and thus offers good creep resistance; remaining dimensionally accurate over a long period of time and through differing environments.

Acetal has a high mechanical strength, relative hardness and stiffness that make it ideally suited for the replacement of steel or other metallic component parts. Acetal is one of the best engineering plastics for slip characteristics and has a lower coefficient of friction than Nylon.

Acetal is an outstanding engineering plastic, it is machinable and leaves a very smooth, high quality surface. With excellent dimensional stability, close tolerance components can be produced. There are two grades available; Copolymer which exhibits slightly better chemical resistance and Homopolymer which exhibits lower thermal expansion, improved mechanical strength, stiffness and hardness.

Other benefits include:

  • Maximum continuous operating temperature range of -50˚C to 100˚C
  • Maximum short term temperature of 130˚C
  • Melt temperature of 165˚C
  • Machinable
  • Smooth finish
  • Low friction
  • Hard wearing
