Sustarin® C – Copolymer

SUSTARIN® C Acetal copolymer has a number of benefits, which include strength, tenacity and toughness particularly in the temperature range of 50-120°C. As a dedicated engineering material, it is now used in applications that were once the domain of metals.

SUSTARIN® C meets EU and FDA requirements for food contact applications except where foodstuffs have 15% or more alcohol content. Also, due to its highly crystalline nature, it has excellent machining qualities resulting in close tolerance parts and an excellent bright surface finish. Natural white and UV resistant black are standard and blue, yellow, green, grey and red colours are available on request.

SUSTARIN® C can be used in "hot water" applications up to 60°C without any hydrolysis affect.

Sustarin C can be characterised by the following properties:

  • High stiffness and hardness
  • Good impact strength at temperatures as low as -40°C
  • Very good stability at high temperatures
  • High dimensional stability
  • Good fatigue resistance
  • Good sliding properties
  • Low coefficient of friction
  • Good electrical insulation
  • Low moisture absorption
  • Good chemical resistance
  • Excellent machining capabilities

Fields of application: Gears, bushes, bearings, food machinery components, impellers, wear plates, bearing cages,
seals, medical parts, electrical insulators and connectors, cams, rollers and precision parts.
