Moisture, conditioning and water content

Down

You are here:

The properties of plastics often depend on the climatic conditions. Some plastics are therefore specially conditioned or air-conditioned.

Pellet moisture is often a disruptive factor for processing, which can lead to material degradation.
After processing, polyamides in particular are specifically moistened in order to achieve optimum properties.

Moisture determination

OMPG has the following options for determining the moisture content of materials and components:

Aquatrac
Drying in an air circulation drying oven
Drying in a vacuum drying oven
Karl Fischer titration

Water absorption

The moisture absorption of plastics can be determined on standardized sample panels 60mm x 60mm x 1 or 2mm in accordance with DIN EN ISO 62.

Rapid conditioning

The rapid conditioning of polyamides in accordance with DIN EN ISO 1110 can be offered both in a climate chamber and in an aluminum-laminated sample bag at 70°C in accordance with VW regulations.
