# Deformulation of joint in the laboratory

## You wish to carry out a deformulation of your joints

### What is a joint?

A gasket is a ring-shaped part installed between two interdependent devices to provide a seal. 

Generally made of polymers, the gasket is a material with elastic properties that allow it to withstand several deformulation actions before breaking. 

Particularly essential in the field of plumbing, gaskets are also used in other fields such as the automotive industry.

### Why deform a joint?

The deformulation of a joint is a method allowing, with the help of various chemical analysis, to determine the nature and the quantity of raw material present in the joint.

Moreover, it allows to better know the studied joint, to better understand the structural problems of this one but also to characterize its quality.

Thus, the deformulation of a joint allows to improve its performance, to better target a supplier or to understand the origin of a failure.

## FILAB supports you in the chemical deformulation of your joints

This approach of polymer deformulation and more particularly of joints allows to answer various needs such as
