TECAFORM® HPV13 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 manyindustrial and military components with moving parts. Additionally, TECAFORM® HPV13 has superior chemical resistance and flexural fatigue properties, as well as low moistureabsorption associated with acetal materials.

  • Lower cost alternative to Delrin AF blend
  • No stick slip
    TECAFORM™ HPV 13 requires less starting torque which provides smooth continuous operation.
  • Low coefficient of friction
  • Good dimensional stability
  • Superior wear resistance
    Improved performance, reliability, and longer life result from TECAFORM™ HPV 13’s excellent wear resistance.
  • Good surface hardness and resilience
  • Superior resistance to repeated impacts and creep
  • Self-lubricating
    The use of TECAFORM™ HPV 13 can eliminate costly lubricants, reduce maintenance costs and product contamination.
  • Excellent machinability
  • Complies with FDA regulation 21CFR 177.2480 and may be used in contact with food up to 150 F on a repeated use basis, except those foods containing more than 15% alcohol. Delrin AF does not.

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.
