PET Shrink Tubing Basics
What Is PET Heat Shrink Tubing
PET heat shrink tubing is a special plastic tube. It is made from polyethylene terephthalate. This tubing is made to shrink when it gets hot. It wraps tightly around things like wires and medical devices. The tubing starts out wide, so it slides over parts easily. When you heat it, the tubing gets smaller and fits tightly. This makes a strong seal to protect the device. The tubing covers every part of the device. It gives good insulation and keeps things safe.
PET heat shrink tubing is clear and strong. It also resists chemicals very well. It is stronger than polyolefin and elastomer tubing. Polyolefin tubing bends more, but PET heat shrink tubing is tougher and clearer. Elastomer tubing stretches more, but PET heat shrink tubing is stronger and stays clear.
Material Properties
PET heat shrink tubing has special features for tough jobs. It is very strong and does not tear easily. The shrink ratio is often 2:1 or 3:1. This helps the tubing fit tightly over many shapes. It can handle heat up to 200°C. This means it can be sterilized. PET heat shrink tubing also blocks electricity well. It keeps electrical parts safe.

PET heat shrink tubing is safe for medical devices. It meets strict rules for biocompatibility. The tubing does not get damaged by most acids or oils. It does not catch fire easily and has no halogen.
How It Shrinks
PET heat shrink tubing shrinks when heated in a special way. First, the tubing is made and stretched while hot. This makes it keep its bigger shape. When you heat it again, it goes back to its smaller size. This makes the tubing wrap tightly around the object. PET heat shrink tubing needs at least 60°C to start shrinking. It shrinks fully above 125°C. This helps it fit well for medical and industrial uses.
Polyethylene terephthalate heat shrink tubing is tough and clear. It also resists chemicals. These features make it a top choice for sealing implantable devices and other important uses.
PET Shrink Tubing for Implantable Device Sealing
Sealing and Protection
PET shrink tubing makes a tight barrier around important parts. It covers things like electrodes, sensors, and connectors. This keeps them safe from dirt and harsh places. The tubing blocks fluids, germs, and other bad things. In medical devices, this barrier keeps patients safe and helps devices last longer.
Researchers made special devices with polyester that have tiny holes, as small as 0.65 μm. These devices stay strong with a pull force over 2N. They can also handle flow pressure under 1N. These facts show PET heat shrink tubing stays strong and seals well in real life. The tubing does not break down from chemicals or stress. This keeps implantable devices safe for a long time.
