PhotoMark® Reflections™ 255
Overview
Typical Properties*
What's better than a durable backsheet with no PET or Fluoropolymers? How about a durable backsheet with no interlayer adhesives? That's right – Tomark-Worthen has created a revolutionary new backsheet based on a proprietary polyamide alloy that is weatherable, dimensionally stable and cost effective - and it does not contain any Fluoropolymer or PET layers and does not use any adhesives! Our backsheet is not susceptible to hydrolysis or UV degradation.
