Ash Content, Moisture & Density Analysis
Three key checks that verify what a masterbatch contains and in what amounts.
Ash Content, Moisture & Density Analysis
-
ISO 3451
Ash content determination
The sample is burned in a furnace at high temperature, and the remaining inorganic residue is weighed. This verifies the content of inorganic pigments and fillers such as titanium dioxide and calcium carbonate.
-
Moisture content
Moisture analysis
Moisture in hygroscopic polymers, fillers, and recycled raw materials causes defects such as porosity, voids, and lensing in film. By measuring moisture content, we identify these risks before production.
-
ISO 1183
Density
Measuring density is a quick way to verify formulation consistency and filler content; density also directly affects the weight and cost of the final product.
What do these checks provide?
- Correct dosage: verifying the declared pigment and filler content
- Cost control: the effect of density and filler content on product weight
- Process reliability: preventing moisture-induced porosity, voids, and film defects
