Ultratape Rubawrap waterproof self-amalgamating tape. 25mm x 5m black tape seals, insulates & protects without adhesive. For electrical & plumbing.
The Ultratape Rubawrap Waterproof Self-Amalgamating Tape is a premium-grade, synthetic elastic tape engineered for superior performance in demanding conditions. Its unique self-amalgamating property means it bonds to itself without any adhesive, creating a seamless, waterproof, and airtight layer that is both durable and reliable. This makes it an essential tool for a wide range of sealing, insulating, and protective applications.
Rubawrap tape is constructed from a strong, elastic material that possesses excellent high-voltage insulating properties and strong resistance to ozone and water. This combination ensures long-term protection against environmental erosion and electrical hazards. A significant advantage is that there is no 'right' or 'wrong' side to the tape, simplifying the application process and eliminating mistakes.
Unlike conventional adhesive tapes, Rubawrap has no sticky, silky adhesive surface. This critical feature prevents the tape from picking up dirt, dust, or other foreign matter during storage or use. It also means the tape won't tangle or stick to itself prematurely, which is a common frustration when working in tight, confined spaces with limited clearance.
Primary Functions
Supplied in a convenient 25mm width and a 5-metre length roll, this black tape is versatile and easy to handle. Its self-fusing nature ensures the repair or seal becomes a solid, homogeneous piece that will not unravel or degrade over time, offering a professional and lasting solution.
