Laboratory

For us, the quality of raw materials supplied shall prevail in the first place.

State of the art laboratory technology supports us in the analysis and testing of different plastics and is our quality assurance.

Laboratory

  • Optical inspection

    For the optical examination includes, of course checking the physical behavior of the plastics when heated, sound test, scratch resistance, and the Beilstein test.

    It is observed:

    • the plastic ignites easy or difficult
    • burns, does not burn, soot, glowing
    • burning outside the flame on or turns off
    • Color of the flame is bright or sooty, plastic is spraying or dripping
    • Smell of smoke after the flame goes out
    • high or low sound
    • soft surface, can be engrave with a fingernail
    • greenish flame lit after being touched by an annealed copper wire (halogen compound in plastic)

     

     

  • Density - test

    The DIN EN ISO 1183 three methods for determining the density of non-cellular plastics are defined, which are present in the form of bubble-free molded or extruded products. Cavities such as holes or gas bubbles distort the measurement result. The procedures listed in the standard are:

    • Determination of the density after immersion method for semi-finished products and molded parts (buoyancy method)
    • Determination of density by liquid pycnometer for particles, powder, flakes, granules or crushed precast
    • Titration method for bubble-free plastics in any form

    In the immersion method, the test is performed on analytical balances or specific for determining the density constructed devices with a measuring accuracy of 0.1 mg.

    To perform the test on the liquid pycnometer an analytical balance with an accuracy of 0.1 mg, a liquid bath with soaking liquid, a pycnometer and a vacuum desiccator are required.

    During titration, the density is determined by narrowing of density differences in test liquids.

  • MFI - Testing

    Under the MFI test is defined as the melt flow index (MFI engl. = melt flow index or melt flow rate MFR) of thermoplastic material. He used to characterize the flow behavior (molding compound examination) of the plastic under certain pressure and temperature conditions. It is a measure of the viscosity of the plastic melt. It can be on the degree of polymerization, that is close the average number of monomer units in one molecule.

    The MFI value is crucial in sales for the distribution of regrinds. The identifiable characteristics at the molecular level is designed for use in recurrent preparatory production
