A hot melt adhesive (also known as a hot melt glue) is a thermoplastic adhesive that usually comes in the form of either hot melt glue sticks or adhesive tapes.
Whether you want to become a hot melt adhesive manufacturer or you want to use hot melt adhesives for your applications, you will need to be conversant with the technical terms that indicate types, specifications and standards for hot melt adhesives.
This guide will familiarize you with some of the key terms related to hot melt adhesives, such as adhesive tapes, melt viscosity, cohesion and shear adhesion.
Adhesive tapeAn adhesive tape is a form of hot melt adhesive. An adhesive tape is a fastening tape which allows temporary or permanent adhesion between objects. These tapes are either single-sided or double-sided and can be activated by water or heat depending on the application purpose.
Self adhesive tapeA self adhesive tape (or a pressure sensitive adhesive tape) is a type of adhesive tape that is sticky at room temperature.
Melt viscosityMelt viscosity is an important characteristic of a hot melt adhesive. In general, as the temperature of a polymer increases, its viscosity decreases. In a hot melt adhesive, the melt temperature controls the viscosity. This controls the degree of surface wetting.
