Silicone Fabrication Q&A
-
Could you discuss the methods that produce the most transparent liquid injection-molded (LIM) silicone device? Could dip-molded silicone be as transparent as the LIM process?Answered September 14th, 2010 by Expert:I know that Nusil Technology has some optically clear liquid silicone rubber materials, and we use a couple of them at Sil-Pro—Nusil MED 6033, for one. The other key is a highly polished mold finish. I am not certain how dip molding would compare, since that process is not my field of expertise. But I would guess that it wouldn’t be as optically clear as LIM molding could be.
