Dielectric Strength: 25 kV/mm
Electricians have critical jobs. Keeping our world powered requires concentration, knowledge and skill. Some of the most dangerous work is done by electricians working on medium and high voltage applications. Ethylene propylene and silicone rubber electrical tapes have the highest dielectric rating of electrical tapes made by 3M and are a trusted product in the toolbox of most medium and high voltage linemen and installers. With proper wrapping, their self-fusing properties help to eliminate voids in critical areas that may cause catastrophic failures .
Adhesives and the resultant tapes made from this class of elastomers is very versatile and the most frequently used. These adhesives typically use styrene butadiene rubber (SBR) or styrene block copolymers such as styrene-butadiene styrene (SBS) , styrene –isoprene-styrene(SIS), or SEBS(styrene-ethyelene/butylene-styrene.. Block copolymers have thermoplastic styrene end blocks with an elastomeric midblock. Different tackifying resins can be used for each distinct phase of the base and the resulting adhesives can be tailored to exhibit aggressive tack, high peel, and excellent cohesive strength. There are a variety of tape products made from these systems including double coated film tapes, transfer adhesives, foam tapes, and carton sealing tapes. These tapes can be used for interior bonding and assembly applications, fabricating foam gaskets and seals, and of course duct tape.
Checking that it meets these standards is crucial when selecting a control box. It’s not just about regulatory compliance; it’s about ensuring the longevity and reliability of your electrical systems.
Additionally, the product’s durability cannot be overstated. Flex Tape is designed to withstand extreme temperatures, making it suitable for use in both hot and cold environments. This resilience ensures that repairs made with Flex Tape will endure the test of time, providing long-lasting solutions rather than temporary fixes. Plus, its resistance to UV rays means it won’t deteriorate or discolor when exposed to sunlight, further extending its life.
The Versatility and Benefits of Self-Fusing Rubber Tape




Another significant benefit of butyl rubber tape is its exceptional sealing properties. It is often used as a waterproofing solution, capable of sealing joints, gaps, and cracks to prevent water intrusion. This feature is particularly valuable in roofing applications, where leaks can lead to extensive damage and costly repairs. Butyl rubber tape can also be used in plumbing to seal pipes and fixtures effectively.
