Polyester Performance Films

Tekra has been the leading distributor of DuPont Teijin Films™ for 25 years, and this includes the expanding line of Melinex® TCH products for the flexible electronics market. This new series of optically-clear PET films affords design engineers the freedom to choose from a variety of functional product types. Examples of polyester performance films that Tekra offers include:

Flame Retardant Films

DuPont Teijin Films™ flame retardant polyester films are halogen-free and combine inherent PET properties with the VTM-0 flame classification performance. 

Index Matched Films

DuPont Teijin Films™ primer is applied to reduce haze and eliminate iridescence resulting from mismatched refractive index coating layers. The applied coating science of Melinex® TCH provides for a low bloom and a crystal-clear surface for transparent conductor film manufacturers. Films are available index matched in either one or two sided options.

Ultra Violet (UV) Stabilized Films

Tekra offers extremely clear polyester films that are engineered to block UV transmission, while also retaining superior mechanical and optical properties.

Thermally Stabilized Films

Dimensionally-stable ST polyester technology (150°C for 30 mins) can be applied to either a variety of Melinex® film types. Our heat stabilization process ensures product consistency and continuity in downstream processing of PET films.
