Mitsubishi Chemical Advanced Materials Ertacetal® H-TF POM-H, PTFE-filled, extruded (ISO Data)
Categories:	Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM); Acetal Homopolymer, PTFE-Filled
Material Notes:	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 Quadrant Engineering Plastic Products is now Mitsubishi Chemical Advanced Materials.
