# Laboratory analysis of PET

## You need a PET analysis

### What is PET?

 First of all, the acronym PET stands for polyethylene terephthalate.  PET is a thermoplastic polyester polymer.

In film form it is semi-crystalline. This film is very strong under tension, stable and transparent and is also a very good electrical insulator.
In addition, the PET used in bottles for gaseous liquids can withstand high pressures of around ten bars.

### Why conduct a PET analysis?

Determining the properties of your PETs is essential in production process or finished product control issues. Moreover, a detailed knowledge of the properties of your PET is necessary to anticipate their evolution in their environment of use.

Indeed, PET is used in a large number of applications such as :

- Textile fibres
- Card holders
- Recyclable bottles
- Disposable packaging
- Cardiovascular prostheses

Thus, the support of a versatile and competent laboratory in PET analysis is necessary in order to respond to all the problems linked to PET.
