• Fatra, a.s. has a well-equipped laboratory, which enables us to verify the parameters of input raw materials and ensure/verify the quality of output materials.

For feed materials, we test the following at the input to the recycling line:

  • Humidity
  • Volatile substances
  • Melt flow index
  • XRS analysis
  • Ash content
  • IPolymer identification using the DSC analysis
  • Density
  • Bulk density

    Our laboratory equipment:

    • continuous quality of inputs
    • check of properties of the re-granulate at the output
    • optional certificates for individual supplies

    tests – parameters of output materials
