The versatility and durability of ESTANE® thermoplastic polyurethane (TPU) make it an ideal solution for screen protection film to protect smartphones, smart watches and flexible displays from everyday life. ESTANE® TPU enables extreme clarity to preserve the aesthetics of modern devices and excellent flexibility to properly cover a variety of screen shapes and sizes.
As dual-curved edge smartphones become more mainstream in many brand’s flagship models, the need for screen protection film for 3D curved displays is on the rise. Polyester (PET) film creates a challenge for designers because it is too stiff to fully cover curved glass edges. PET film also interferes with the sensitivity of fingerprint unlocking on touch screens. As an alternative to PET film, Lubrizol offers a variety of thermoplastic polyurethane (TPU) solutions to complement different film structure designs. To help customers solve flexible and full coverage protection, we developed a series of TPU grades with excellent optical and protection performance attributes specifically for screen protection film.
