PC DX LED
PC DX LED or Exolon® DX (Diffusion eXellence) is a plastic diffuser sheet that combines excellent light-diffusing properties with a high level of translucency. Its properties are based on modern diffuser technology, which enables even light distribution and excellent translucency properties. Exolon® DX disguises LED light sources. It offers high-quality light distribution at a lower lighting capacity than standard light-diffusing materials. The material is also available as fire-retardant PC FR DX LED for applications such as boats and trains where self-extinguishing materials must be used. We deliver PC DX LED as sheets.
