The Composition of Hot Melt Adhesive Tape
Hot melt adhesive tape is composed of synthetic polymers that are solid at room temperature but melt when heated. The key component of this tape is the hot melt adhesive, which is typically made from a mixture of ethylene-vinyl acetate (EVA), polyethylene, and/or polypropylene. These materials provide excellent adhesion properties, thermal stability, and resistance to aging. Furthermore, the adhesive is usually mixed with additives, such as tackifiers, plasticizers, and stabilizers, to enhance its performance and durability.
The backing material of hot melt adhesive tape can vary depending on the specific application. Common backing materials include paper, film, cloth, and foam. Each type of backing material offers distinct properties, such as strength, flexibility, moisture resistance, and temperature resistance, making hot melt adhesive tape suitable for diverse environments and uses.
