Royalex
Encyclopedia
Royalex is a composite material
, comprising an outer layer of Vinyl and hard acrylonitrile butadiene styrene
plastic (ABS) and an inner layer of ABS foam. The layers are bonded by heat treatment.

s. Royalex is lighter, more resistant to uv damage from sunlight, is more rigid, and has greater structural memory than non-composite plastics used for this purpose, such as polyethylene. It is also quieter, faster, and more user friendly in cold or hot conditions than aluminium. Royalex canoes are, however, more expensive than aluminium canoes or canoes made from traditionally molded or roto-molded polyethylene hulls.
It is heavier, and less suited for high-performance paddling than fiber-reinforced composites, such as fiberglass, kevlar, or graphite.
Composite material
Composite materials, often shortened to composites or called composition materials, are engineered or naturally occurring materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct at the macroscopic or...

Development
Royalex was developed by the Uniroyal company but in 2000 the Spartech Corporation took over the Uniroyal Royalex Manufacturing Division and secured the rights to manufacture Royalex at their factory in Warsaw, IndianaWarsaw, Indiana
Warsaw is a city in and the county seat of Kosciusko County, Indiana, United States. Cradled among Winona Lake, Pike Lake, Hidden Lake and Center Lake, Warsaw is nicknamed "Lake City," though other cities in the surrounding area are also referred to by that nickname...

Uses
Royalex is used for the manufacture of canoeCanoe
A canoe or Canadian canoe is a small narrow boat, typically human-powered, though it may also be powered by sails or small electric or gas motors. Canoes are usually pointed at both bow and stern and are normally open on top, but can be decked over A canoe (North American English) or Canadian...

Hull (watercraft)
A hull is the watertight body of a ship or boat. Above the hull is the superstructure and/or deckhouse, where present. The line where the hull meets the water surface is called the waterline.The structure of the hull varies depending on the vessel type...
