Abstract

Hollow mouldings are mfd. by rotational casting of a liquid or powdered synthetic resin contng. a uniform dispersion of hollow vitreous particles. Pref. the mixture also incorporates glass fibres. Pref. the product is a flotation aid for underwater construction or for fishing equipment. Use of the hollow fillers imparts sufficient compressive strength for deep sea use while remaining a highly buoyant structure. Rotational casting is sufficiently insensitive to density differentials to allow a uniform wall structure to be obtained.
