TECAFORM® HPV13

About
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. 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. Lower cost alternative to Delrin AF blend No stick slip Low coefficient of friction Good dimensional stability Superior wear resistance Good surface hardness and resilience Superior resistance to repeated impacts and creep Self-lubricating 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.&&
