Bus bar. A common method of insulating a bus bar connection is to first wrap it with two layers of varnished cambric. The subsequent steps consist of four half-lapped layers of rubber or rubber mastic followed by two half-lapped layers of premium vinyl tape.
This tape can be used for wire identification, seaming and splicing of films, and surface protection. Available colors are clear, black, white, and red. Widths range from one-fourth of an inch (6 millimeters) to 44 inches (1,118 millimeters).
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.

Overall, PVC electrical insulation offers a versatile and reliable solution for a wide range of applications. Its high dielectric strength, flexibility, durability, and cost-effectiveness make it a popular choice for electrical wiring, cabling, and other applications. Whether used indoors or outdoors, PVC insulation provides a safe and effective solution for insulating electrical conductors and preventing electrical leakage. With its many benefits, it's no wonder that PVC electrical insulation is a go-to choice for many industries.
Pure acrylic adhesives share the following characteristics:
Water-activated adhesives are very popular for packing tape. When the adhesive is used on cardboard, the bond it creates is so strong that the tape cannot be removed without damaging the cardboard. As a result, it is the perfect tamper-evident packaging. No one can open a box sealed with water-activated tape without leaving obvious evidence. Water-based is the cheapest of all adhesives.
