Polyvinyl chloride (also known under its acronym “PVC”) is a widely-used substance. It is essentially derived from simple ingredients: petroleum, titanium and salt. Globally, over 50% of PVC manufactured is used in construction. In addition to its good physical properties, PVC has excellent, chemical resistance, long-term stability, flammability resistance, good weather ability, flow and insulatory electrical properties.
Rigid applications, accounting for 60 % of total vinyl production, are concentrated in construction markets which include windows, doors, railing, fencing, pipe and fittings, siding as well as carpet backing. As a building material PVC is affordable and easy to assemble. In recent years, PVC has been replacing traditional building materials such as wood, concrete and clay in many areas.
