Technical Data Sheets

Optical properties of Pylux

The family of Pylux™ materials all provide amorphous backbones, which leads to a variety of desirable optical properties useful for display applications. Namely, the high transparency, low color and low haze of Pylux™ films allow for clear and high-fidelity transmission of light directly through the polymer. Additionally, the exceptionally low birefringence of Pylux™ is similar to that of glass panels currently used in rigid LCD manufacturing. This allows for Pylux to be incorporated into the optical path of flexible display manufacturing without the need for compensating elements which add thickness and cost to the display module.

A highly-tunable set of thermomechanical properties

The Pylux platform offers a wide range of thermomechanical properties that can be tuned precisely to fit needs of the specific end-product. Glass transition temperature, modulus, max operational temperature are only examples of the characteristics that can be designed for to enable new products without sacrificing the optical properties.
