CLAREX HiTemp Cast Acrylic Formulation (W7)
For high temperature applications, we have a HiTemp formulation which is good up to 95oC
CLAREX HiTemp (W7) Cast Acrylic formulation maintains the same optical grade quality and mechanical properties as the standard formulation, but can withstand up to 95oC continuous working temperature (versus 85oC for the standard formulation). This formulation could be used as a base for all the different CLAREX options like diffusers, optical filters, NIR windows, and more….
