If you have ever experienced a tacky mess when trying to bond laminates under high temperatures, Stevens Urethane has a solution with its new "super-high-melt" polyether thermoplastic polyurethane (TPU). Stevens ST-1665 is said to provide one of the highest melt temperatures available in a thin urethane film, between 190 and 210C. Because it requires a higher than usual temperature to become tacky and bond with other materials, its strength and barrier characteristics are not affected by processing temperatures that might melt "normal" urethane films. In multi-layer laminations, the material is typically used on the "high-heat" side of the lamination. The high-melt urethane maintains its integrity and performance properties, while films on the other side of the substrate soften and bond, forming a multi-layer lamination.
