ARTICLES EN MATIERES PLASTIQUES ANTISTATIQUES

摘要

A method of rendering plastic articles resistant to the accumulation of static electricity, and articles produced thereby, are disclosed. The process comprises contacting a molded plastic article with an aqueous non-ionic emulsion of polyethylene, followed by removal of the water by evaporation. Treated articles are thus characterized as bearing on their surface the evaporation residue of such emulsions. The invention is particularly useful for treating nestable cups of foamed thermoplastic material, advantageously of foamed polymers of styrene.
