Abstract: A non-crosslinked polymeric heat shrink tubing including poly(ether-block-amide) (PEBA) and methods for making such non-crosslinked polymeric heat shrink tubing is provided. The non-crosslinked PEBA heat shrink tubing disclosed herein finds application, e.g., as a processing aid and final component in the manufacture of catheters and other medical devices.

Abstract: Polymeric coated optical elements are described herein, which exhibit good optical properties, e.g., low attenuation. Some such coated optical elements comprise an optical element (e.g., an optical fiber) having an outer surface and a thermoplastic polymeric tight buffer coating on at least a portion of the outer surface of the optical element, wherein the polymer-coated optical element exhibits a first attenuation at room temperature of plus or minus about 50% the attenuation of a comparable optical element with no thermoplastic polymeric tight buffer coating thereon, and a second attenuation at room temperature after thermal cycling to a temperature of at least 170° C. that is about 2 times the first attenuation or less.

Abstract: A radiopaque lined heat shrinkable tubing is disclosed. A non-limiting example of a radiopaque lined heat shrinkable tubing is a multilayer construction having an inner layer and an outer layer, wherein the inner layer includes a thermoplastic that is highly loaded with a radiopaque filler, and the outer layer includes a fluoropolymer heat shrink tube.
