Ertacetal H-TF is a DELRIN® AF Blend, a combination of TEFLON® fibres 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 TEFLON fibre which is softer, less stiff and slipperier than virgin acetal resin. Compared with 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.

• High mechanical strength, stiffness and hardness
• Excellent resilience
• Good creep resistance
• High impact strength, even at low temperatures
• Very good dimensional stability (low water absorption)
• Good sliding properties and wear resistance
• Excellent machinability
• Good electrical insulating and dielectric properties
• Physiologically inert (most grades are suitable for food contact)
• Not self-extinguishing
