Ensinger Tecaform™ HPV 13 Acetal Homopolymer - Extruded Products (POM)
Categories: Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM); Acetal Homopolymer, PTFE-Filled

Material Notes: Tecaform™ HPV 13 is a brown homopolymer acetal with an internal PTFE lubricant. Its low coefficient of friction, excellent PV values, toughness, wear resistance, and machinability make it an exceptional material for use in many industrial and military components with moving parts. Additionally, Tecaform™ HPV 13 has superior chemical resistance and flexural fatigue properties, as well as low moisture absorption associated with acetal materials.

Uses: Tecaform™ HPV 13's range of exceptional properties makes it an ideal engineering plastic for use in precision instruments and measuring devices, as well as in many critical components in the automotive, aviation, military, industrial, food processing machinery, business equipment, and specialty valve areas.
