The ability to create strong, permanent bonds with other substrates is a critical requirement for materials used in composite manufacturing. Fortunately, TPU Film exhibits excellent adhesion characteristics and can be bonded to fabrics, metals, and other plastics using several common industrial methods. Thermal bonding is highly popular, where heat and pressure are applied to melt the surface of the film slightly, allowing it to fuse directly into the fibers of a textile substrate. This creates a monolithic composite material that will not delaminate, even when subjected to repeated washing cycles or intense flexing. In addition to heat sealing, these films are highly compatible with polyurethane-based liquid adhesives and reactive hot melts for complex multi-layer lamination processes. High-frequency welding and ultrasonic welding are also widely used to create airtight and watertight seams in products like medical bags and life vests. The material melts consistently under these wave frequencies, creating a weld joint that is often stronger than the surrounding un-welded material itself. This incredible processing versatility allows designers to create complex, multi-material products with high structural integrity and streamlined manufacturing workflows.
