LSR (Liquid Silicone Rubber)
Sur-Seal® Liquid Silicone Rubber (LSR) is precisely the optical solution you’ve been searching for. In optics and lighting, material degradation is a constant frustration. PMMA, polycarbonate and glass wind up yellowed, deformed and easily damaged over time.
A drawn-out, iterative design process is necessary simply to try and reduce the long-term effects of degradation on performance.
Optical grade silicone overcomes all these challenges at once, while simultaneously offering unmatched material performance and design flexibility.
