SPECIAL RECOMMENDATIONS
Special RecommendationsThicknesses from 7.5micron up to 125micron. · Various thermal control materials are available with single and double-sided metallisation; vacuum deposited aluminium (VDA). · Precise thermo-optical properties depend on the exact thickness used. · There also exists a higher temperature version called Upilex S.
