Fluoro-Seal International LP

Treating the surface of wood-plastic composite (WPC) boards with fluorine gas in the presence of oxygen oxidizes the surface so that ordinary paints and primers adhere as they do to natural wood.

Coex blow molding has the inside track, but makers of small gas tanks and jerry cans are also looking at fluorination and other monolayer systems. Rotomolders, too, are considering multilayer alternatives.

Fully automated rotomolding equipment for nearly lights-out operation, a new approach to balancing molds, and a new oven design that trims space and energy requirements mark some of the new developments unveiled at the 27th Annual Fall Meeting of the Association of Rotational Molders (ARM), held in October in Toronto.
