- Medical silicone can be made radiopaque by the addition of compounds such as titanium oxide and barium sulfate. These medical silicones are even available in restricted implantation grade (short term/ twenty-nine days or less) and unrestricted implantation grade (long term/indefinite).
- Silicone hardness is measured and classified as the durometer of the silicone. The standard tolerance for durometer fluctuation in industry is +/- 5. This means that Shore A 60 durometer silicone could have a durometer as low as 55 or as high as 65.
- Colorants may be added to silicone to improve part visibility and marketability. These colorants can be matched to a pantone color or an existing part (this can be particularly useful for preserving your own unique brand by color matching silicone parts to the company logo).
- Injection molded silicone parts can be processed in such that their cycle times are as fast as those of injection molded plastic parts.
