Hot melt adhesive is the default adhesive for many tapes. It is used in polypropylene (PolyPro) tapes. It is made of thermoplastic polymers and as a result, it has good adhesion, excellent holding power, and a high tensile strength. Hot melt adhesive tapes have three layers: the non-adhesive surface layer, the release layer, and the adhesive layer. Holt melt adhesives tend to be more durable than acrylic adhesives. They can withstand large temperature fluctuations without warping or becoming brittle.

In 1845, a surgeon named Dr. Horace Day made the first crude surgical tape by combining India rubber, pine gum, turpentine, litharge (a yellow lead oxide), and turpentine extract of cayenne pepper and applying that mixture to strips of fabric. It was the first “rubber-based” adhesive and Dr. Day used it in his practice as a surgical plaster. Larger scale manufacturing of similar medical tapes began in 1874 by Robert Wood Johnson and George Seaburg in East Orange, NJ. That company would soon become the Johnson & Johnson Company we know today. Later in 1921, Earle Dickson who bought cotton for Johnson & Johnson noticed that the surgical tape kept falling off his wife Josephine’s fingers after cutting them in the kitchen. He fixed a piece of gauze to some cloth backed tape and the first Band-Aid ® was invented. It took almost 75 years from Dr. Day’s first crude tape until the early 1920’s when the first industrial tape application appeared. The application was electrical tape (although the adhesive was more of a cohesive film than the electrical tape we know today) to prevent wires from shorting. The second major industrial tape application was a result of the rise of the American automobile in the 1920’s. Two-toned automobiles were becoming popular and automakers needed a way to produce clean, sharp paint lines while using the new automatic paint spray gun. They started using the surgical tape that was available but the paint wicked through the cloth backing and caused defective paint jobs. Richard Drew, an engineer at Minnesota Mining and Manufacturing (3M) happened to be at a local body shop testing their WetorDry® brand sandpaper in 1925 and he saw the workers struggling to get clean paint lines. He went back to his lab and created a 2-inch wide crimp backed paper tape that became the first “masking tape” for painting. Jumping ahead to 1942 and World War II, Johnson & Johnson developed duct tape to seal canisters and repair equipment for the military. The tape was a basically a polyethylene coated cloth tape with good “quick stick” properties that made it easy to use in the field for emergency repairs. The world never looked back and duct tape can be found in almost any home or toolbox.

• Moreover, gymnasium floor tape serves as a safety measure. Its high-visibility colors, such as bright yellow, red, or blue, catch the eye, alerting individuals to potential hazards like wet floors, slippery areas, or areas under maintenance. The tape's non-slip surface provides added traction, enhancing grip and minimizing the risk of slips and falls.
• End-sealing cables: Provides a moisture-proof seal at the ends of high voltage and communication cables.

• Polyethylene tape can be used as construction tape, masking tape, patching tape, repair tape, or stucco tape. Stucco tape is a heavy-duty construction tape that can adhere to numerous types of surfaces, like stucco. It’s not limited to stucco, however. You can use it for concrete, brick, metal, vinyl, and wood.

• The unique properties of butyl rubber make it an ideal material for waterproofing applications. Butyl rubber is known for its excellent resistance to water, chemicals, and UV rays, making it highly durable and long-lasting. It also has a high level of elasticity, allowing it to flex and move with the underlying surface without losing its waterproofing capabilities. This flexibility ensures that butyl rubber waterproofing remains effective even in changing weather conditions or structural movement.
