What Is PET Heat Shrink Tubing?

Key Features and Benefits

PET heat shrink tubing is made from polyethylene terephthalate. This material is used for medical devices because it has many good qualities. When you heat the tubing, it gets smaller and fits tightly around wires or parts. This makes a strong and safe cover.

Some important benefits are:

• Biocompatibility means it is safe for devices that touch the body.

• High flex fatigue lets the tubing bend many times without breaking.

• Intense tensile strength gives strong and steady protection.

• It helps make devices smaller and thinner, so you can design advanced tools.

• Enhanced features with less bulk make devices easier to use.

PET heat shrink tubing gives clarity, durability, and chemical resistance. These features help keep devices safe and working well.

Common Uses in Medical Devices

PET heat shrink tubing is used in many medical devices. Catheters are one of the main uses. The tubing gives precision and strength, which are needed for these delicate tools. It fits tightly to complex shapes, so you get better structure. High strength and thin walls help make catheters light but strong. The clear tubing lets you check the device during assembly.

PET heat shrink tubing also protects sensitive parts. Its mechanical strength, dimensional stability, heat resistance, and chemical resistance make it a good choice for medical uses. You can use this tubing to cover sensors, connectors, and other parts that need extra safety. This keeps your devices safe and reliable when used.

Tip: When picking heat shrink tubing for medical devices, always think about what your device needs. The right tubing can make your device safer and work better.

How to Select PET Heat Shrink Tubing

Picking the right PET heat shrink tubing is very important. You want your device to be safe and work well. It also needs to follow all the rules. This guide will show you the main steps for choosing the best tubing.

Application Requirements

First, think about what your device needs. Every medical device is not the same. The tubing must match the job of your device. Here are the main things to check:

Always check if the tubing is good for biocompatible uses, surgery tools, and healthcare. This helps stop contamination and keeps patients safe.

Tip: Write down what your device needs before you shop for tubing. This helps you follow the rules and pick the best one.

Sizing and Shrinkage (Radial & Axial)

Getting the size right is very important. If the tubing is too big or small, it will not protect your device. Measure the part you want to cover. Pick tubing that is 20-30% bigger than the largest part. This helps the tubing shrink and fit well.

• The tubing should fit tight with a gap of 15% or less.

• Do not use tubing more than 15% bigger than your part.

• A 1.1:1 shrink ratio is best for most medical uses.

PET heat shrink tubing can shrink over 20% if you heat and hold the ends. This makes the tubing fit tight and protects wires and parts.

Always check the rules for sizing and shrinking. This helps you avoid mistakes and keeps your device safe.

Activation Temperature Range

You need to know the right heat for shrinking the tubing. PET heat shrink tubing works best between 70°C and 190°C. The best shrinking happens at 150°C. This makes the tubing fit tight and protects well.

• Long-term temperature: -196°C to 135°C

• Short-term temperature: Up to 200°C

• Melting point: 235°C

If you use the wrong heat, the tubing may not shrink right. This can cause problems with safety and contamination.

Note: Always follow your supplier’s heating rules. This keeps your tubing strong and safe.

Material Properties

Look for tubing with strong material features. PET heat shrink tubing gives you:

Check for chemical resistance, contamination resistance, and good covering. These things help your device last longer and stay safe.

• ISO 10993-5: Checks for cell safety (<30% cell death)

• ISO 10993-10: Checks for irritation

• MDR 2023: Checks for leachable stuff in blood devices

These rules make sure your tubing is safe for people and follows all laws.

Compliance: FDA-Approved PET Heat Shrink Tubing
