PSA Hot Melt Adhesives
PSA hot melt adhesive, standing for Pressure-Sensitive Adhesive, is a unique type of hot melt adhesive that remains tacky and soft even after cooling and setting. This characteristic allows for the adhesive to form a bond upon the application of light pressure, without the need for any solvent or water for activation. PSA hot melts are known for their versatility, easy application, and strong, durable bonds. They adhere well to a wide range of surfaces, including plastics, metals, paper, and wood. These adhesives are commonly used in label manufacturing, packaging, automotive trim attachment, and in various medical applications such as adhesive bandages and wound dressings. The key features of PSA hot melt adhesives include their flexibility, instant bonding capabilities, and long-term aging properties, making them a popular choice in numerous industries.

Hot Melt Pressure Sensitive Adhesives
Pressure-sensitive adhesives (PSA) are physically hardening systems which are characterized by a permanent tackiness. Pressure-sensitive adhesives are frequently used for precoating while the bonding can be carried out independently of the adhesive application in a different place and at a different time.
