Mastic Tape Made of Self-Fusing Butyl Rubber

What is Butyl Tape Sealant?

Butyl tape is an example of a synthetic rubber adhesive. It’s a solvent-based adhesive that is formulated in the lab instead of coming from a rubber tree. All types of rubber adhesive are thermoplastic, so exposure to high heat will soften the adhesive and impact its effectiveness. However, butyl adhesives are formulated to be less sensitive to temperature variations. They stay more flexible in cold weather and more stable in high temperatures than natural rubber adhesives. Because butyl tapes are extremely durable, with have good flex properties, they are often used in applications where an airtight bond is required. In fact, most butyl tapes also come with a liner since the adhesive system is aggressive and forms a permanent bond to the surface it sticks to – even if that surface is itself!
