Classification Detail

This class includes manufacture of plastics in primary forms, including: polymers of ethylene, of polypropylene or of other olefins, of styrene, of vinyl chloride or other halogenated olefins, of vinyl acetate or of other vinyl esters, other vinyl polymers; polyacetals, other polyethers and epoxide resins; polycarbonates, alkyd resins, polyallyl esters and other polyesters; polyamides; amino resins, phenolic resins and polyurethanes; silicones; petroleum resins, polyterpenes, polysulphides, polysulphones; cellulose and its chemical derivatives; natural polymers (e.g. alginic acid), modified natural polymers such as hardened proteins; or ion exchangers based on the above polymers. Manufacture of synthetic rubber and factice derived from oils, in primary forms. Production of mixtures of synthetic rubber and natural rubber or rubber-like gums (e.g. balata), in primary forms.
