Ash content of plastic materials (polyolefins)
Gavimetric determination for the examination of films, granules etc. based on polyolefins (PE, PP) for percentage of inorganic fillers, pigments, anti-blocking agents etc. The chalk content of white pigments can be calculated from the weight loss due to carbonate splitting during two-stage annealing 600/950 °C. Further analytical investigations of the ash composition are possible on request.

This test determines the total amount of inorganic additives, such as fillers, pigments, or anti-blocking agents, present in polyolefin materials like PE or PP. A sample is heated in a furnace to burn off the organic plastic components, leaving behind only the inorganic residue, which is then measured gravimetrically.
The resulting ash content value indicates the proportion of non-combustible materials in the packaging film or granulate. This information is used to verify material specifications, ensure consistent product quality, and check for compliance with formulation requirements regarding additives.
