Tape can be divided into the high-temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, and die-cutting tape according to its function. Different functions are suitable for different industry needs. The surface of the tape is coated with a layer of adhesive to make the tape stick to the object. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. 1. The principle of use of tape Adhesive tape is composed of two parts: substrate and adhesive, which connect two or more disjoint objects by bonding. Its surface is coated with a layer of adhesive. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesives can stick to things because their molec...
