LUBRICANTS FOR THE PROCESSING OF PLASTIC MATERIALS

摘要

LUBRICANTS FOR THE PROCESSING OF PLASTIC MATERIALS of the disclosure: By extraction with aliphatic hydrocarbons, waxes having a light color are obtained from tree-barks, which waxes may be oxidized, saponified, esterified or amidated. These waxes and their derivatives are suitable as lubricants for plastic materials, especially poly(vinyl chloride). They may also be used in admixture with other waxes, for example natural or hydrocarbon waxes or the derivatives thereof.
