Polytetrafluoroethylene (PTFE) Insulating Tape KCF4

Polytetrafluoroethylene (PTFE) Insulating Tape KCF4 is a high-performance, non-adhesive tape made from PTFE film. Offering outstanding chemical and thermal stability, with a melting point of 327°C (621°F) and decomposition temperature of 415°C (779°F). 


KCF4 is highly inert to most chemicals and solvents, offering excellent resistance to weathering, aging, oil, and water, as well as flame retardancy and mechanical toughness. Rated Class C, KCF4 operates continuously from -110°C to 250°C (-166°F to 482°F), with superior electrical dielectric properties.
