Density of plastic materials

DIN EN ISO 1183-1, of mono films, granules, moulded articles etc. made of polyolefins, PVC, or Polyamide. PET samples must have a minimum thickness of 0.3 mm, thin PET films cannot be tested with this method.

In short — AI-generated

This test determines the density of plastics such as polyolefins, PVC, or polyamide by measuring the mass and volume of a sample. According to DIN EN ISO 1183-1, the material is weighed and then immersed in a liquid to calculate its density based on the displacement principle. Please note that for PET samples, a minimum thickness of 0.3 mm is required, making this method unsuitable for thin PET films.

The resulting density value serves as a key material characteristic for quality control and identification of raw materials. It allows packaging developers to verify material consistency, calculate material consumption, and ensure that the plastic used matches the required specifications for the intended application.

Required Sample Amount: 10 g material, in the case of laminated films, the mixed density is determined.

Standard Tests

Density by immersion method

Specific Norm: DIN EN ISO 1183-1

This method is intended for granules, monofilms and other meltable monomaterials. The method is usually not suitable for determining the mixed density of plastic films or other multilayer materials.
