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.
