PolyPeel™ Peelable Polyester Heat Shrink Tubing

Peelable polyester heat shrink provides manufacturers with a PFAS-free, highly precise, and easy-to-remove alternative for a wide range of catheter manufacturing and reflow processing applications. Engineered with ultra-thin walls—down to 0.00025 inches—it delivers the delicate balance of durability and flexibility needed for masking, bundling, and in-process containment without compromising device profiles. Its low recovery temperature, as low as 85°C (185°F), helps safeguard sensitive substrates from heat damage during shrink operations, making it ideal for reflow processing and other thermal manufacturing steps.

This specialized heat shrink enables seamless, discrete coating applications by masking specific catheter sections with tight dimensional control. Its high-strength construction supports mid-process containment requirements, such as stent crimping, while maintaining the geometry of balloons, implants, and delivery systems throughout processing. The material’s consistent, tight-tolerance inner diameter—up to ±0.001 inches—also ensures reliable bundling of multiple components, aiding in sleeve insertions and assembly operations that require uniform, compact packaging.

One of its defining advantages is its peelability, which allows clean and efficient removal without skiving. This significantly reduces scrap associated with substrate nicks, scoring, or damage caused by traditional removal methods. By eliminating PFAS from the material composition, manufacturers gain a compliant and future-ready shrink solution that aligns with evolving regulatory and sustainability expectations.

For applications demanding controlled shrink performance, precision masking, and repeatable processing outcomes, peelable polyester heat shrink delivers reliability, safety, and process optimization run after run.
