Why PET Heat Shrink Tubing

Chemical Resistance and Biocompatibility

When you pick PET heat shrink tubing for medical devices, you get a material that can handle harsh conditions. This tubing does not get damaged by sterilization agents like gamma radiation, ethylene oxide, or hot steam. You can clean it with strong chemicals, oils, and disinfectants, and it still works well. PET heat shrink tubing keeps its shape and stays strong after many times being sterilized. This makes it a good choice for important medical jobs and sensitive procedures.

PET heat shrink tubing follows strict rules for biocompatibility. You can use it safely when it touches patients because it meets ISO 10993 and USP Class VI standards. These rules make sure the tubing does not cause bad reactions in the body. You also get good quality control with FDA Quality System Regulation and ISO 13485, which are needed for medical-grade products.

Certification / Standard	Purpose / Description
ISO 10993	Tests for biocompatibility in contact with human tissue
USP Class VI	Confirms safety for body-contact medical uses
FDA Quality System Regulation (QSR)	Ensures safe, high-quality medical device manufacturing
ISO 13485	Requires consistent production and traceability for medical devices

Low Shrink Temperature

You want heat-shrink tubing that works with delicate parts. PET heat shrink tubing shrinks between 70°C and 190°C, and most people use it at about 150°C. This temperature range lets you put on the tubing without hurting sensitive medical parts. PET heat-shrink tubing keeps its strength and shape during sterilization, so you can use it many times in medical places.

Material	Temperature Resistance
PET	Long-term: -196°C to 135°C; Short-term: up to 200°C
PTFE	Up to 232°C
PPS	Up to 260°C

Thin Wall and High Strength

PET heat shrink tubing gives a thin but strong layer to protect medical devices. The wall can be as thin as 0.0001 inch, which is good for very small devices. Even though it is thin, the tubing has a tensile strength of at least 30,000 PSI. This means your devices stay strong and bendy, even in small spaces. PET heat-shrink tubing fits tightly around tricky shapes, so you get good protection and support.

You get high-quality PET tubing that lasts through many sterilizations.
The tubing’s strength helps your devices handle stress and tough conditions.
PET heat shrink tubing meets biocompatibility and medical standards, so it is great for medical uses.

You can count on PET heat shrink tubing to work for today’s medical devices. It helps with making things smaller, keeping them strong, and staying safe, all while following strict medical rules for biocompatible uses.

Application in Endoscopic Clip Applicators
