    Abstract

    This materials study demonstrates a testing program based on the requirements of protective glove material against metal cutting fluids in workshops and steel industries.

    Permeation testing using various cutting fluids, puncture testing using a standardized penetrometer needle, and tensile strength testing indicated that nitrile rubber is the most protective material. By X-ray fluorescence analysis it was demonstrated that chromium and nickel, which act as allergens, can permeate glove materials when the metals are present in cutting fluids. The results of the permeation test showed a breakthrough time of less than 2 to 3 h for natural rubber and neoprene. Nitrile without additives showed a breakthrough time of >5 h and resistance to puncturing by a force of more than 25 N. The tensile strength test showed a strength of approximately 6 N/mm2 for nitrile and 12 N/mm2 for neoprene, measured at the breakthrough limit.

    The primary requirements were resistance to cutting fluids and to puncture from work pieces. The secondary requirements were that the glove material should be able to break apart when drawn into moving machine parts and that the glove should be thin and elastic from the functional point of view (grip comfort and tactility).

    The authors conclude that nitrile rubber latex best performs the requirements.
