Silicone Fabrication Q&A
-
I am currently working on a medical device in which a needle pierces through a silicone septum. I can’t use silicone oil. Is there any other medical-grade lubricant that can be used to aid the needle through the silicone?Answered December 17th, 2229 by Expert:I am not aware of any other medical-grade lubricant. One additive we sometimes use in applications is Zonyl. Teflon can also be loaded into the silicone prior to molding (~15% by weight). This creates some added lubricity throughout the part.
