Polyvinyl Chloride (PVC)

PVC - polyvinyl chloride (PVC) is one of the most versatile plastics and due to this feature it is one of the most studied and used in the today’s materials. 
 PVC is a thermoplastic resin which is produced when vinyl chloride molecules associate to form macromolecular chains. This process is called polymerization and can be accomplished in several ways. The two main processes for the production of PVC polymerization are emulsion polymerization and suspension.
Both use a semi- continuous process, the reactor is fed with the vinyl chloride monomer ( MVC ) , additives and catalysts. The polymerization reaction occurs in an aqueous medium. Differences between suspension and emulsion processes manifested in the size and characteristics of PVC grains obtained. PVC obtained by these methods is used according to the application and the results to be obtained with the PVC.
Produced from salt ( NaCl ) and especially from oil , is one of the most widely used plastics today. The main advantage of PVC is its versatility.

This versatility makes the PVC present in our daily lives in various sectors of the economy:

•    Construction ( liners , window profile , pipe, fittings , bathroom rugs , wires and cables , garden hoses , flooring , expansion joints , etc ... )

•    General industry ( rigid profiles , safety boots , gloves , hoses with and without rigid soul and etc ... 

•    Industry toys

•    Automotive ( electrical wiring , side moldings , hoses etc ... )

•    Industry shoes ( soles, sandals and so on ... )

•    Medical industry / hospital ( bags of blood and serum, catheters , connectors , etc ... )

•    Food industry ( stretchable films , bottles , etc. . )

Key features of PVC 

•    Durability : made from PVC products have long life , enabling its application in durable goods such as water and sewage pipes , wires and cables , industrial profiles , windows , ceilings , etc. ...

•    Non-flabillionable : owing to the chlorine in its molecule , PVC will not burn or ignite easily alone. For this reason it is extensively used to insulate and protect electrical cables and other inputs in the construction , automotive , appliances, household goods , etc. industry.

•    Chemically Stable : generally PVC has good resistance to acids and bases which enables its use in the medical industry / hospital, food and industrial . Due to their chemical inertness PVC packaging preserves the organoleptic properties of the packaged product.

•    Energy recovery : PVC has a high energy value . In modern systems of waste energy recovery , where emissions are very subsidiaries , PVC can provide energy and heat in industry , homes or elsewhere.

•    Easy to process : working with appropriate equipment , PVC is processed in most industrial processing of thermoplastic materials ( injection , extrusion , calendering , blow , etc ... )

•    Easy to recycle : due to being a thermoplastic resin PVC is 100 % recyclable.

•    Barrier properties : low permeability to oxygen and carbon dioxide which enables its application in food industry.

•    Resistant to light

•    Good Thermal Insulation and Acoustic

•    Excellent Cost / Benefit
