Optical properties of

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.

Pylux H.

Pylux-H has been specifically formulated for high surface hardness and increased glass transition temperature. These properties make it an ideal polymer for flexible cover lens and flexible touch panel substrate applications.
Pylux-H can be processed at up to 200°C featuring all of the exceptional optical performance characteristics of the Pylux™ polymer family. Pylux-H offers a great combination of mechanical and thermal properties in addition to compatibility with R2R processing.

Pylux MF.

Pylux-MF has been specifically formulated for microfabrication. Films can be processed indefinitely at 275°C, and up to 300°C for short periods of time (e.g. 30min).
Combined with our proprietary release layer, Easybond (Link a sección de Easybond), films can be easily detached from a rigid carrier via mechanical peeling, at the end of the fabrication.

Technical Data Sheets

Pylux W.

Pylux-W has been specifically formulated for high optical transmittance, in addition to energy dissipation. As such, the elastomer can act as a combined optically clear adhesive (OCA) and an anti-shock protection layer, replacing two layers in the front-plane with one. Pylux-W is offered either as coatable resin (UV-curable just like the rest our Pylux™ family of resins) or in film form. Pylux-W offers an exceptional value by combining two functional layers into one film without compromising function and target values for optical and energy dissipation characteristics.
