70% Shrinkage PET Heat Shrink Tubing

PET Material

PET heat shrink tubing is made from polyethylene terephthalate, or PET. This plastic is strong and tough. PET does not let water in, so it keeps wires safe from water. It also blocks chemicals and oils. This makes PET heat shrink tubing good for hard jobs. PET keeps its shape when heated. It does not melt or fall apart easily. You can use PET heat shrink tubing where it gets hot or there is a lot of pressure.

Tip: PET heat shrink tubing follows strict safety rules. It passes ISO 10993 and USP Class VI tests. This means you can use it for medical tools and electronics.

Here is a table that lists some key facts about PET heat shrink tubing:

PET heat shrink tubing gives strong protection, even in hard places.

Shrinkage Ratio

PET heat shrink tubing has a high shrink ratio. This means it can get much smaller when heated. The 70% shrinkage PET heat shrink tubing can shrink its width by up to 70%. This lets you cover many shapes and sizes. You always get a tight fit.

The product guide says this tubing can get 70% thinner. This shows how well it shrinks. You can use it on wires, connectors, or odd shapes. The tubing wraps close and leaves no open spots. This keeps out dust, water, and chemicals.

Note: A high shrink ratio means you only need one size for many uses. You do not have to buy lots of different sizes.

How It Works

PET heat shrink tubing is made in a special way. First, factories melt PET pellets and make them into tubing. They stretch the tubing and cool it fast. This keeps the tubing wide.

Next, the tubing is cross-linked. This uses radiation, like electron beams or UV light. Cross-linking helps the tubing remember its small size.

When you heat the tubing with a heat gun, the PET gets soft. The tubing remembers its small shape and shrinks tight around what it covers. The high shrink ratio lets the tubing shrink a lot for a snug fit.

Here is a table that explains the steps:

You can use PET heat shrink tubing for many things. It works for electrical insulation and medical device safety. The high shrink ratio and strong PET material give safe, lasting coverage.
