PTFE (TEFLON™) Cables
PTFE (TEFLON™) Cables
High Temperature | Chemical Resistant | High Performance Cables
Vision International manufactures premium quality PTFE / FEP insulated cables designed for extreme operating conditions. These cables are specially engineered to perform reliably in high-temperature, chemically aggressive, and compact installations.
PTFE cables can carry higher current compared to standard PVC insulated wires of the same cross-section, making them ideal for space-constrained and high-performance applications.
