- Whether you need to patch up a leaky pipe or seal a cracked surface, Flex Tape Black is up to the task. Its strong adhesive backing creates a tight seal that prevents water from seeping through, making it ideal for both indoor and outdoor use. The flexible tape can easily conform to irregular shapes and surfaces, ensuring a secure and long-lasting repair.
Electrical tape is an adhesive tape that is used specifically for electrical phasing and wiring jobs. Used as a safety measure, electrical tape is applied to any wires or cables which will conduct electricity, to protect and insulate them. Electrical tape is available in different types, depending on the material it is made from, including cloth electrical tape, mastic electrical tape, vinyl electrical tape, rubber electrical tape, and PVC electrical tape.

Overall, self-fusing tape is a versatile and valuable tool that has a wide range of uses. Whether you're a DIY enthusiast looking for a quick and easy way to fix plumbing or electrical issues, or a professional tradesperson in need of a reliable sealant for various applications, self-fusing tape is a product worth considering. Its strong bonding properties, resistance to heat and water, and ease of use make it a must-have item for any toolbox.

The benefits of using fire seal tape extend beyond mere compliance. Properly installed fire seal tape contributes to the overall efficiency of a building’s HVAC system by preventing air leaks. This can result in lower energy costs, as the heating and cooling systems do not have to work as hard to maintain desired temperatures.
Silicones have been used to formulate adhesive products for decades due to their flexibility, temperature cycling resistance, chemical resistance, and wide range of possible material properties.
Tape thickness is usually measured in the United States in “mils”, or thousandths of an inch (1/1000”). The thickness can be measured from the bottom of the adhesive surface to the top of the outer surface or simply the film itself. In most cases, the thicker the tape the stronger and more durable it is. This is referred to as tensile strength. Thinner tape tends to be used for lightweight or temporary applications whereas thicker material is required for sealing heavy boxes and other heavy-duty applications. Duct tape is a great example of a thick adhesive roll whereas painting tape is often very thin and hand tearable.
