PET Heat Shrink Tubing Overview

What Is PET Heat Shrink Tubing

PET heat shrink tubing is a special tube made from PET. PET stands for polyethylene terephthalate. It forms when two chemicals join together. These chemicals are terephthalic acid and ethylene glycol. PET has ring groups in its structure. These rings make it strong and able to handle heat. PET melts at very high temperatures, between 225°C and 265°C. This makes it good for many jobs. PET is partly crystal-like, so it stays tough and clear. These things make PET a good pick for medical use. It works well when devices need to last and handle heat.

PET heat shrink tubing is known for being thin and able to shrink. The walls can be as thin as 0.0001 inches. The tubing can shrink to fit tightly around wires or parts. It shrinks across and along its length. The tubing can get up to 70% smaller in diameter but stays strong. Most PET heat shrink tubing comes in sizes from 0.006 inches to 0.5 inches wide. The tubing fits tightly, leaving almost no gap. This is important for medical-grade tubing.

PET heat shrink tubing is used in medical devices because it is strong and thin. It can shrink to fit tightly. It protects wires and parts inside devices. This helps them work safely and last longer.

PET heat-shrink tubing is also liked for medical use because it resists chemicals. It can be cleaned and sterilized without getting damaged. PET heat shrink for neurostimulator lead insulation uses these features. It keeps the leads safe and working well.

Key Features of PET Heat Shrink Tubing:

• Thin walls (as thin as 0.0001")

• High strength and durability

• Shrinkage capability up to 70%

How It Works

PET heat shrink tubing works by using heat and stretching. First, the tubing is treated with an electron accelerator. This step makes the tubing stronger and more stable. Next, the tubing is heated and stretched to make it bigger. After cooling, it keeps this bigger shape until it is used.

To use PET heat shrink tubing, you put it over the part you want to protect. Then you heat the tubing again. The heat makes the tubing shrink back to its original size. It wraps tightly around the object. This gives a smooth, tight fit that protects what is inside.

1. The tubing is made stronger with an electron accelerator.

2. It is stretched and cooled to keep its shape.

3. When used, the tubing is put over the part and heated.

4. The tubing shrinks to its original size and seals tightly.

5. Even heating and slow cooling stop bubbles and wrinkles.

PET heat shrink tubing is important for medical use. It is used in neurostimulator lead insulation. It gives a tight, protective layer that keeps the leads safe.
