- The primary function of weatherstrip seals is to seal gaps and cracks around doors, windows, and other openings. This helps to minimize heat loss during winter and prevent excessive heat gain in summer, thereby reducing the workload on heating and cooling systems. As a result, energy consumption and associated costs are significantly lowered, making weatherstripping an effective and cost-efficient method for improving a building's energy efficiency.
Self-bonding rubber tape, often referred to merely as rubber tape, is an innovative solution that has transformed the way we think about sealing, insulating, and repairing various materials. This unique type of tape is characterized by its ability to bond to itself without the need for adhesives, making it an invaluable tool in numerous applications, from electrical work to plumbing and beyond.


First, let’s talk about the product itself. Flex Tape comes in various sizes and colors, but the white 4” x 5’ version is particularly useful for a range of applications. The tape features a thick, rubberized backing that promises to conform to any shape, thereby creating a permanent, waterproof seal. This characteristic makes it ideal for both indoor and outdoor uses.

What Is Electrical Tape
One of the most impressive demonstrations of Flex Tape's strength is its ability to hold heavy objects in place. Whether it's a broken chair, a loose shelf, or a damaged car bumper, Flex Tape can be used to provide a temporary fix until a more permanent solution can be found.


Another noteworthy feature is its resistance to extreme temperatures. Self-fusing rubber tape can typically withstand temperatures ranging from -20°C to 150°C (-4°F to 302°F), making it suitable for both high- and low-temperature environments. This attribute makes it especially useful in electrical applications, automotive repairs, and around the home, where temperature fluctuations are common.

Another benefit of 3mm electrical tape is its flexibility and stretchability. This allows for easy application around curved surfaces or irregular shapes, ensuring a snug and secure fit. The adhesive backing of the tape also provides a strong hold, preventing it from unraveling or slipping off over time. This makes it a reliable choice for long-term installations or repairs.
