Adhesive vinyl electrical tape cannot create a permanent waterproof seal and removing the tape creates a sticky mess. Butyl rubber tape can be hard to work with and deforms at high temperatures or when compressed. Impervious to temperatures from -65F to +500F and most chemical solvents, Proxicast’s Pro-Grade Self-Fusing Silicone Tape can be used in almost any environment indoors or out. Proxicast’s heavy-duty 30 mil silicone tape is 50% thicker than other premium silicone tapes. Extra thickness means better protection for rough, sharp and uneven surfaces without applying extra layers. Thicker tape provides more abrasion resistance and better insulation. Proxicast’s silicone tape is also 50% wider than most other brands for faster wrapping and fewer seams. Perfect for protecting CATV & RF coaxial antenna connectors and electrical plugs from damaging moisture, this premium tape is 1.5″ wide, 30 mil thick and each 15 ft roll can cover approximately 6 typical connections.
