Vinyl is a type of plastic or polymer that is derived from petroleum, natural gas, or coal. Vinyl is produced by taking the hydrocarbon ethylene and the element chlorine, and through a process called polymerization polyvinyl chloride resin is formed. Chemical additives and modifiers are added to the polyvinyl resin to give it specific properties depending on the specific end use. The raw vinyl material is then formed or extruded to create thousands of products including vinyl fencing This strong, moldable, and easy to clean plastic is why a vinyl fence from Poly Enterprises lasts so long!
