General Information
DF-PN1000 is a virgin PTFE (Polytetrafluorethylene), also known as Teflon or F4, in white color. It is noted for its outstanding chemical properties and the lowest coefficient of friction among solid materials. The material is suitable for a wide range of applications due to its broad temperature range (-180°C to +260°C) and mechanical properties.
