3M™ Temflex™ 165 is a durable and flexible vinyl electrical tape, designed for general-purpose electrical applications, both indoors and outdoors. Made from flame-retardant PVC, the tape offers high resistance to moisture, abrasion, alkalis, acids, and solvents, making it a reliable solution for insulating, bundling, and marking low-voltage cables. It can be used as primary insulation for wires and as an auxiliary material for repairs or harness forming. The product is compatible with rubber and synthetic compounds, with an operating temperature range of 0°C to 90°C.
Available in a wide range of industry-standard colors. Manufactured using an innovative solvent-free process, which results in lower emissions and a more environmentally friendly product (excluding green-yellow color).
