Silicone and Silicone Plus diaphragms
Overview
Silicone and Silicone plus diaphragms
Medical grade platinum-cured silicone diaphragms meet USP Class VI and FDA 21 CFR 177.2600 standards.
We provide two different finishes to our silicone diaphragms, white which is made with Q7-4765 and 0.25 % titanium dioxide or clear with no titanium dioxide.
We also offer a Parylene surface treated version doubling the longevity of the diaphragm.
Features and benefits
- All our diaphragms are laser-etched with cure dates and batch numbers, ensuring that they are completely traceable
- Medical grade silicone available in white or clear finish
- Widely used in pharmaceutical applications
- Parylene surface treated version also available
