PVC

Polyvinyl Chloride (PVC) – A polymer made by the catalytic polymerization of vinyl chloride. PVC also includes copolymers that contain at least 50% vinyl chloride. The neat homopolymer is hard, brittle and difficult to process, but it becomes flexible when plasticized. Hence, PVC comes in two basic forms rigid and flexible. Rigid PVC is strong, difficult to burn, has excellent resistance to strong acids and bases, to most other chemicals, and to many organic solvents. PVC can be made softer and more flexible by the addition of plasticizers, the most widely used being phthalates. Apart from Rigid & Flexible PVC, PVC can be compounded with various different recipes much more than any other polymer. PVC being the least expensive plastics with different compounds available can be extruded, injection molded, compression molded, calendered, and blow molded to form a huge variety of products. Polyvinyl Chloride is the world’s third-most widely produced synthetic plastic polymer (after PE and PP). About 40 million tons of PVC are produced each year gradually increasing year on year

Rigid PVC

Rigid PVC (polyvinyl chloride) is a strong, stiff, low cost plastic material that is easy to fabricate and easy to bond using adhesives or solvents. PVC is also easy to weld using thermoplastic welding equipment. It is frequently used in the construction of tanks, valves, and piping systems.

Flexible PVC

Flexible PVC is a soft, flexible material that ranges in appearance from transparent to opaque. PVC is manufactured with plasticizers, which confer rubbery properties on the end product. By adjusting the type and amount of plasticizers, plastic molders can achieve a large range of flexible compositions

PVC Paste

PVC pastes are liquid or semi-liquid suspensions, comprising—as the essential components—PVC polymers (paste grades, made by the emulsion or microsuspension process) and plasticisers: various additives are also usually present in a paste, as required for processing and product properties.
