Ertacetal® C
Ertacetal C (POM-C) is Quadrant's copolymer acetal grade. Next to the standard natural grade, there is also a series of special colors available all showing a FDA food contact compliant composition. The acetal copolymer is more resistant to hydrolysis, strong alkalis and thermal-oxidative degradation than the acetal homopolymer.
Ertacetal® H-TF
Ertacetal H-TF (POM-H + PTFE) is a Delrin® AF Blend, a combination of PTFE fibers evenly dispersed in a Delrin acetal resin. Much of the strength that is inherent in Ertacetal H is retained. Some properties change due to the addition of PTFE fiber which is softer, less stiff and more slippery than virgin acetal resin. Compared to Ertacetal C and H, this material offers superior sliding properties. Bearings made of Ertacetal H-TF show low friction, long wear and are essentially free of stick-slip behaviour.
Ertacetal® H
Ertacetal H (POM-H) is Quadrant's homopolymer acetal grade. It offers a higher mechanical strength, stiffness, hardness and creep resistance as well as a lower thermal expansion rate and often also a better wear resistance than the acetal copolymer.
Ertacetal® C LQ
Quadrant has developed this specific laser-writable Ertacetal® product since the standard POM-C natural grade does not show markings with common laser technologies (e.g. IR-YAG, UV-YAG).
Instead, the surface of standard POM-C just experiences burning but no visible dark marking.
The new product shows identical physical properties and machinability as Quadrant’s standard Ertacetal® C natural [POM-C] product and is available in a bright-white, less transparent colour.
Ertacetal® C LQ POM-C is processed by extrusion technology.
