Protective gloves.

The glove material has to be impermeable and resistant to the product/ the substance/ the


Selection of the glove material on consideration of the penetration times, rates of diffusion and the


· Material of gloves

PVC gloves

The selection of the suitable gloves does not only depend on the material, but also on further marks

of quality and varies from manufacturer to manufacturer. As the product is a preparation of several

substances, the resistance of the glove material can not be calculated in advance and has therefore

to be checked prior to the application.
