TECAFORM® AD HPV13 brown
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 many industrial and military components with moving parts. Additionally, TECAFORM® HPV13 has superior chemical resistance and flexural fatigue properties, as well as low moisture absorption associated with acetal materials
