PETG Heat Shrink Tubing

What Is PETG

You might wonder why PETG is different. PETG means polyethylene terephthalate glycol. This plastic is a copolyester. Glycol is added to regular PET to make PETG. This makes PETG bend easier and stay clear. It also helps PETG not break as easily. PETG is used in many places because it is strong and safe for food and water. You can find PETG in medical models, packaging, and 3D printing. PETG is easy to recycle, so it is good for the planet. When you use PETG, you get a tough and clear material. It is also easy to shape and print.

PETG has a special chemical structure. It is made from terephthalic acid and ethylene glycol. Extra glycol units are added. This makes PETG amorphous, so it does not have a regular crystal pattern. Because of this, PETG stays clear when you heat or shape it. PETG keeps its strength and clarity even after many uses.

How PETG Heat Shrink Tubing Works

PETG heat shrink tubing uses PETG’s special features to protect things. When you heat the tubing, it shrinks tightly around your item. This happens because PETG is a thermoplastic. The polymer chains inside move and relax with heat. This lets the tubing squeeze down and fit well.

First, you put the PETG heat shrink tubing over your item. Then you use a heat source, like steam or a heat gun. As it gets hotter, the tubing starts to shrink. Most PETG tubing shrinks fast at about 82°C. It can go back to its shape in seconds. The tubing can shrink up to 60% in some cases. This depends on how it was made and what is mixed in. For example, adding polycarbonate changes how much and how fast it shrinks. If you heat it below 130°C, the shrinkage may stop in one direction. Polycarbonate can limit chain movement.

The seam quality in PETG heat shrink tubing is very important. Different seaming agents change how much the tubing can shrink before the seam breaks. You can see in the table below how each agent works:

Some seaming agents let the tubing shrink more before the seam fails. E5 lets the tubing shrink up to 60%. This means you get great shrink performance with the right materials and process.

The heat shrinking process for PETG heat shrink tubing is quick and works well. You put on the seaming agent, weld the seam, and use heat to shrink the tubing. The process uses steam at about 95-100°C for around 7 seconds. The tubing shrinks most in the middle, and the seam must stay strong.

PETG melts at about 260°C. This high melting point means the tubing can take heat without losing its shape. You get a product that is tough, clear, and bends easily. PETG can shrink more than 75% across its width. This makes it great for sleeve labels and covers. Mixing PETG and PET can change how stiff or strong the tubing is. You can pick the tubing that fits your needs.

When you pick PETG heat shrink tubing, you get something clear, strong, and flexible. You can use it for packaging or electrical insulation. PETG shrink film gives you a safe and reliable way to protect your things.

Tip: Always check the shrinkage rate and seam quality before using PETG heat shrink tubing for important jobs. This helps you get the best results and avoid problems.

Properties of PETG
