# Determination of the mineral load of a polymer in the laboratory

## Your needs: determine the mineral load of your polymer materials

### What is a mineral charge?

A mineral filler of a polymer is a solid material of mineral origin dispersed in the polymer studied. Generally introduced in powder form, the mineral filler plays several roles. Indeed, it allows to reduce the cost of a material or to modify its characteristics.

The most commonly used mineral fillers are :

- quartz
- mica
- talc
- chalk

In addition, mineral fillers are used in many polymeric materials such as paints and plastics.

### Why determine the mineral content of your polymer materials?

As previously stated, mineral filler is, among other things, added to a polymer in order to modify its characteristics. Moreover, depending on the field of application of your products, the mineral filler content is different to meet your needs.

Indeed, for a paint for example, a too low or too high mineral content, directly impacts the visual (more or less smooth).

Thus, the analysis of the mineral content of your polymers by a specialized laboratory is an important step in the development and optimization of your products.

## FILAB assists you in determining the mineral load of your polymer materials.

For more than 30 years, our laboratory FILAB has had the experience and the specific [analytical equipment](https://filab.fr/en/our-technical-resources.md) to assist industrialists in solving their problems related to mineral filler in polymers by providing its customers with the know-how and experience of its team.

## Examples of services

[Thermogravimetric analysis ATG, ATG-FTIR and ATG-MS](https://filab.fr/en/our-technical-resources/tga-tga-ftir-and-tga-ms-analysis-at-filab-laboratory.md) to determine the decomposition temperature of the product, as well as its percentage of mineral fillers

[Scanning Electron Microscopy (SEM/EDX)](https://filab.fr/en/our-technical-resources.md) allows morphological observations and local semi-quantitative chemical analysis of the product fillers

[X-ray Diffraction (XRD)](https://filab.fr/en/our-technical-resources/x-ray-crystallography-laboratory-xrd.md) to determine the nature of the crystalline phase(s) constituting the product's fillers.

[ICP-AES optical](https://filab.fr/en/our-technical-resources/laboratory-analysis-icp-icp-ms-icp-aes/icp-aes-analysis-laboratory.md) emission spectrometry to determine the chemical composition of mineral fillers
