Acetron™ C Sterra™ POM-C is a general purpose, copolymer acetal grade with recycled contents that is often favored for its porosity-free nature. This recycled POM-C also exhibits low moisture absorption and excellent machinability capabilities, making it a very versatile material that can excel in a multitude of environments.
As part of the Sterra™ product portfolio, Acetron™ C Sterra™ POM-C contains recycled POM-C and therefore is associated with a significantly lower carbon footprint compared to similar materials derived from non-recycled feedstocks. For details, please refer to the respective environmental datasheet.
Stock shapes made from Ertacetal™ C ELS POM-C (copolymer acetal) exhibit excellent electrical conductivity qualities, low moisture absorption, high strength and stiffness and great machinability capabilities. This grade in particular is recommended for use in electrical and explosion sensitive applications.
Ertacetal™ C LQ POM-C is a white/natural-colored copolymer polyoxymethylene specifically developed for laser writability via IR-YAG and UV-YAG technologies. The acetal copolymer itself is more resistant to hydrolysis, strong alkalis and thermal-oxidative degradation than the homopolymer acetal grad and offers identical physical properties and machinability to the standard Acetron™ GP/Ertacetal™ C POM-C, including low moisture absorption and porosity-free composition.
Acetron™ VMX FG POM-C (Food Grade) is an EU 10/2011 and compositional FDA 21 CFR § 177.2470 compliant copolymer acetal containing metal and x-ray detectable additives and has bright blue coloring for ease of visual detection. This material has been specifically tailored for use in the food processing and packaging industries where it can easily be traced by different detection systems installed to detect physical contamination in foodstuffs. Additionally, Acetron™ VMX FG POM-C presents good mechanical strength, stiffness and impact strength, making this grade especially well-suited for different applications like gears, scrapers, grippers, etc.
Acetron™ AF Blend/Ertacetal™ H-TF POM-H is a unique thermoplastic material for use in moving parts where low friction and long wear resistance are important. The material has a high strength, toughness, dimensional stability and good machinability as well as improved wear characteristics over unfilled POM-H. Unblended Acetron™ AF Blend/Ertacetal™ H-TF POM-H offers a slightly higher limiting PV and lower coefficient of friction due to additional PTFE content. This added PTFE typically decreases the wear capability and impact strength. Acetron™ AF 100 is available on a custom basis.
