Patent number: 9533134Abstract: Silicone tube structures are formed having a particular dimensional accuracy. In one embodiment, a silicone tube structure can include an extruded hollow body having an inner bore. The extruded hollow body can have an inner diameter, an outer diameter, and a length of at least approximately 20 m. The extruded hollow body can also have a dimensional accuracy that is measured by the standard deviation of the inner diameter being no greater than approximately 0.8% of an average inner diameter of the extruded hollow body over the length. In an embodiment, the silicone tube structure can be cut to form a number of silicone tubes.Type: GrantFiled: April 18, 2013Date of Patent: January 3, 2017Assignee: SAINT-GOBAIN PERFORMANCE PLASTICS CORPORATIONInventors: Adam P.
