PhotoMark® Reflections™ is a durable PV backsheet with no interlayer adhesives, PET or fluoropolymers.

This revolutionary new backsheet is based on a proprietary polyamide alloy that will not deteriorate with exposure to UV light or moisture. Stable and cost effective, PhotoMark® Reflections™ backsheets use known materials that are proven in outdoor applications.

These backsheets are manufactured using a single, co-extrusion process. Unlike PET-based systems that still rely on two layers of adhesive in the construction, PhotoMark® Reflections™ eliminates multiple manufacturing steps, which saves money and production time. This process is also environmentally safe because it does not use solvents. In addition, PhotoMark® Reflections™ backsheets are customizable from three to five layers, making easy color changes possible.

We also supply an entire line of backsheets to the solar market, as outlined below.
