Designed to retain mechanical and optical properties in applications involving UV exposure, DuPont has announced the launch of super clear Ultra Violet (UV) stable polyester films. These new films are specifically designed to block UV transmission, and they are the most recent additions to the company’s Melinex TCH family of low haze and low oligomer bloom films that are perfectly engineered for flexible electronics, displays, photovoltaic, lighting and label markets.
These new Melinex TCHUV films from DuPont will provide customers with cost-effective substrate solutions that are ideal for a wide variety of UV light sensitive applications. Bi-axially oriented, semi-crystalline polyethylene terephthalate (PET) films have many desirable properties for a wide range of applications, including dimensional stability, chemical resistance, tensile strength and electrical insulation. Standard PET polyester films transmit light above approximately 315nm wavelength, however, extended UV exposure can lead to changes in optical and mechanical properties such as colour and film brittleness.
