Abstract

Plastic material suitable for the manufacture of pots for centrifugal apparatus is made from phenol formaldehyde resin and ebonite, by heating finely divided ebonite in molten phenol formaldehyde resin until the ebonite absorbs the resin and is brought to a jelly like condition. The product hardens on cooling and may be used to produce moulded articles after being powdered. Fillers may be added. Specification 350,855, [Group II], is referred to.
