Zanite polymer composite is a blend of pure silicon dioxide ceramic (99.8%) quartz aggregate, specially formulated high strength epoxy resin and selected additives. The natural elliptical shape of quartz is ideal for casting intricate structures.

Zanite replaces traditional materials such as iron, aluminum, and steel used in the manufacture of machine bases. Castings are manufactured to tight finish tolerances, and the resulting base out-performs alternative material in many areas.

Zanite polymer composite is accepted by design engineers throughout the world as an alternative material due to its excellent design flexibility, mechanical properties, and short production time.
