What is Polyvinyl Chloride (PVC)?

Polyvinyl chloride (PVC), is a synthetic resin made from the polymerization process of vinyl chloride thus deriving the name Poly-Vinyl-Chloride. PVC Pipe & Fittings usage in the world is only second behind Polyethylene (PE) within the plastics consumption notably the Plumbing & Piping application from Domestic or Industrial uses.

Most of PVC plastic are used in the manufacture of pipes for plumbing and piping, which are employed in industrial and municipal applications. Due to the PVC Properties which are strong, lightweight and low-reactive, making them well-suited in sanitary, underground-wiring and water-distribution applications.

PVC water pipes do not wear, rot or rust, and are a dependable and affordable material for potable-water piping. There are different types of PVC pipes, including Schedule 40, Schedule 80, Schedule 120, CPVC (chlorinated polyvinyl chloride) and Gray Schedule 40. PVC Schedule 40 are the most popular and commonly used for common piping and plumbing application.

PVC Pipe Application

There are many uses for PVC. As a rigid plastic, it is used as vinyl siding, magnetic stripe cards, window profile, pipe, plumbing and conduit fixtures. PVC is commonly used as the insulation on electric wires. Frequently in applications where smoke is a major hazard (notably in tunnels) PVC-free LSOH (low-smoke, zero-halogen) cable insulation is used.

Polyvinyl Chloride (PVC) is one of the most widely used polymers in the world. Due to its versatile nature, PVC is used extensively across a broad range of industrial, technical and everyday applications including widespread use in building, transport, packaging, electrical/electronic and healthcare applications. PVC is a very durable and long lasting material which can be used in a variety of applications, either rigid or flexible, white or black and a wide range of colours in between. The first patent for a polymerisation process to manufacture PVC was granted to German inventor Friedrich Klatte in 1913 and PVC has been in commercial production since 1933. The material now accounts for about 20% of all plastic manufactured world-wide, second only to polyethlene.
