What Is Butyl Tape? Everything You Need To Know

Fire-resistant electrical tape is typically made from durable materials such as PVC (polyvinyl chloride), which can endure higher temperatures than standard tapes. These tapes are coated with flame-retardant compounds that significantly reduce the risk of ignition when exposed to heat or flames. Some products may also have a backing made of fiberglass or other inherently flame-resistant materials, adding an extra layer of protection.

In general, rubber based adhesives are not UV or oxidation resistant which is why they tend to be used predominantly in interior applications. Having said that, antioxidants and UV stabilizer packages can be added to the formulation to help mitigate these weaknesses. Some synthetic elastomers exhibit vastly improved UV stability over natural rubbers. Chemical resistance can also be problematic as is resistance to elevated service temperatures (typically 180- 200°F at the top end). The great strength of rubber-based adhesives is their wide formulation latitude.  These adhesives can be compounded to be removable, repositionable, or extremely permanent. High strength foam bonding tapes can be made from rubber based adhesives or easily removable masking products can also be offered. Rubber based adhesive adhere to many surfaces including low surface energy plastics such as polypropylene and polyethylene. And to top it all off, rubber based adhesives are economical. They get the job done at a very fair price! Adhesive tapes made from rubber based adhesives have come a long way since Dr. Day’s first surgical tape and they still offer a cost-effective way to bond, seal, and protect.
