s PRODUCT DATASHEET 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.
