Acetal

Acetal sheet and rod is used in many demanding applications. Acetal plate was utilized for these profiled impact guide bars

  Acetal, also referred to as Delrin*, has good frictional and wear properties and minimal slipstick excellent for bearings and moving parts.  It has excellent dimensional stability and does not absorb water. Acetal, or Delrin*, is ideal when used for cam and gears for business machines, bearings for appliances and automobiles.  It is also often used for slides for food processing machinery

 Acetal sheet has a strength retention at elevated temperatures. Moisture has only a moderate effect in changing properties of acetal. The stiffness of Acetal makes it a leading choice for a material to resist bending under loading.
 Acetal sheet has an excellent ability to withstand cyclic stressing.
Even with a wide range of temperatures, bearing loads, and relative surface speeds acetals static and dynamic coefficients of friction remain nearly unchanged.
  High strength and creep resistance together make acetal the best choice where permanent holding power is required as with self-tapping screws or interference fits
Black acetal sheet has outstanding wear resistant characteristics. Acetal will retain all its qualities when exposed to air or liquids at elevated temperatures. Acetal also has excellent dielectric properties Black acetal is UV stable.
  Acetal, or Delrin®, is a thermoplastic polymer manufactured by the polymerization of formaldehyde. The chemical composition, regular structure and high crystalinity of acetal resins give parts made of acetal a combination of physical properties not available with metals or other plastics.
