we supply self-amalgamating tape manufactured from ethylene propylene rubber which is weatherproof and rugged enough to cope with the demands of most applications, including roofing and sailing where it is used as rigging tape. There are silicone self-amalgamating tapes which offer a slightly higher voltage rating than ethylene propylene rubber but these offer much poorer tear resistance.
3. Measure and Cut Measure the length of the gap that needs sealing and cut the butyl weather stripping accordingly. It’s advisable to cut a little longer than necessary, allowing for a snug fit.
Not all tapes are created equal – some are better suited for high heat applications, while others are not.
2. Superior Adhesion Butyl rubber features high adhesive properties that allow it to bond effectively to various surfaces, including wood, metal, and plastic. This characteristic ensures a tight seal against drafts, moisture, and dust, enhancing the overall energy efficiency of your space.
Rubber tapes are generally non-adhesive, and are either equipped with a liner or are linerless. Stretched and overlapped layers will fuse or bond together to form an effective electrical insulation and moisture barrier. For low-voltage (1000V or less) applications, rubber tapes should be stretched during wrapping so that tape width is reduced to approximately 75%. For high- and medium-voltage applications — where the electrical stresses are high (e.g. connector areas, lug areas, and cable shield cut-back areas) — tape should be stretched just short of its breaking point.
Overlap Layers: For added strength, consider overlapping multiple layers of tape. This is particularly important in high-pressure or high-temperature applications.
