Acetron® AF Blend / Ertacetal® H-TF POM-H is a unique thermoplastic material for use in moving parts in which 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.
