tesaflex® 4163 is a specially formulated electrical tape with good film flexibility and an acrylic adhesive. Due to the UV- and weathering-stable acrylic adhesive, the tape is perfectly suitable for permanent and outdoor applications. The soft PVC insulation tape is resistant to solvents and acids and features good electrical insulation and printability. tesaflex® 4163 is universally applicable, though it is exceptionally qualified for applications in repairing, masking, and electrical insulation. The PVC-backing makes for high durability strength, and the acrylic adhesive ensures a high adhesion to polar surfaces. Furthermore, the tape conforms to US safety standard 302. tesaflex® 4163 is available in many colors: black, white, grey, blue, yellow, red and green. The grey color is perfect for the installation of water pipes. Typical widths are 12 mm and 19 mm (more available) and are offered in 33 meter length.
