Common Defects to Watch For

When you want to know how to identify pet heat shrink tubing, you must look for common defects. Quality pet heat shrink film should not have folds, bubbles, or magazines. These defects can stop the tubing from shrinking evenly. You may see folds as lines or creases on the surface. Bubbles look like small raised spots. Magazines appear as streaks or patches inside the tube. If you find any of these, the heat shrinkable tube may not give you uniform shrinkage.

Here is a table to help you spot defects:

You should always check for these defects during visual inspection. If you find any, choose another piece of pet heat shrink film. This step helps you get reliable uniform shrinkage every time.

Note: Comparing the strength and bendability of the heat shrinkable tube can help you confirm your choice. Pet tubing bends easily and keeps its shape. You get a tight fit and a neat finish.

PET vs. Other Heat Shrinkable Tube Types

When you choose a heat shrinkable tube, you want to know how pet heat shrink film compares to other materials. Each type has its own look and performance. You can spot differences in clarity, gloss, wall thickness, and flexibility. These features help you pick the right tube for your project and get uniform shrinkage every time.

PET vs. Polyolefin

Polyolefin is a common heat shrinkable tube. You see it in many electrical jobs. Polyolefin tubing looks more matte and less shiny than pet heat shrink film. You notice that polyolefin does not have the same clear transparency. Pet stands out because you can see through it and check the wires inside. Polyolefin feels thicker and less flexible. Pet heat shrink film bends easily and gives you a tight fit. You get better uniform shrinkage with pet because the walls are thin and the color stays even. Polyolefin may show more defects like folds or bubbles. Pet heat shrink film keeps a smooth surface and a glossy finish.

Tip: If you need to inspect parts inside the tube, pet heat shrink film is the better choice.

PET vs. PVC

PVC is another popular heat shrinkable tube. You see it in many colors and sizes. PVC tubing looks less clear than pet heat shrink film. The surface is not as glossy. You find that PVC has thicker walls, which can make uniform shrinkage harder to achieve. Pet heat shrink film has thin walls, from 0.00015 to 0.004 inches, while PVC walls are usually thicker than 0.005 inches. Pet gives you better flexibility and a lighter feel. You get superior electrical insulation and higher temperature resistance with pet. PVC ages faster and does not resist UV rays as well. Pet heat shrink film lasts longer and keeps its shape.
