Optical properties

Specifically designed for transparency Optical properties Transparency Slide 23 (hidden): Optical properties As explained before, KrystalFlexTM products are based on aliphatic isocyanates. Besides, OA TPU films offer high light transmission. These products were specifically designed to improve film transparency. Transparency is a key property for the manufacture of many products in the glazing industry, for example for bullet-proof glass. One other advantage of aliphatic isocyanates is to obtain a film resistant to UV light degradation: no yellowing is encountered. It also prevents from cracking. The film shows therefore excellent optical clarity and has a long life-time. For example, OA TPU film is already used as interlayer for optical filters. To ensure that the product will play its role properly, it is compulsory to have highly transparent interlayer. Aliphatic based TPU High light transmission Specifically designed for transparency
