DuPontTM Tedlar® PVF films are available as either biaxially oriented or unoriented cast film. The biaxially oriented film is stretched to various degrees in both the machine and transverse direction during manufacturing, imparting a range of different mechanical properties on the product depending on the amount of molecular orientation. The amount of orientation is described by the film type, listed as the last digit on the product code. The unoriented film, also known as ‘SP’ film, is cast onto a PET carrier web and is sold with the PET web attached.
DuPontTM Tedlar® PVF films required specialized adhesives in certain applications.
