Density is generally measured within polymeric materials to understand the variations in structure and overall composition. It can also be used to evaluate material uniformity for application into various end use products.

Common Standards 

  • ASTM D792—Standard Test Methods for Density and Specific Gravity (Relative Density) of Plastics by Displacement
  • ISO 1183—Plastics — Methods for determining the density of non-cellular plastics — Part 1: Immersion method, liquid pycnometer method and titration method
