What is Low Surface Energy (LSE)

Low Surface Energy - surface energy is a substrates (surface) ability to allow a tapes adhesive to bond to its surface. The higher the substrates surface energy the easier it is for the tape to adhere to the object ensuring a high contact surface area of bonding resulting in a higher level of tape performance. A low surface energy substrate will have difficulty for a standard tape to adhere to it. A low surface energy substrate requires a tape that is made for low surface energy applications.
Examples of Low Surface Energy (LSE) substrates: Acrylic, polyethylene, polystyrene, polyurethane, PVC.
Examples of High Surface Energy (HSE) substrates: Aluminiun, Anodized Aluminium, copper, glass, stainless steel
