Standard Practice for Resistance of Plastics to Sulfide Staining

Importancia y uso:

4.1 Plastic compositions containing salts of lead, cadmium, copper, antimony, and certain other metals (as stabilizers, pigments, driers, or fillers) may stain due to the formation of a metallic sulfide when in contact with external materials that contain sulfide. The external sulfide source may be liquid, solid, or gas. Examples of materials that may cause sulfide stains are rubber, industrial fumes, foods, kraft paper, etc. This practice provides a means of estimating the relative susceptibility of plastic composition to sulfide staining.
