If you are active in the field of polymers and related industries, you have surely heard the name PVC multiple times. PVC, or Polyvinyl Chloride, is one of the most widely used and valuable polymers in the world. Due to its unique properties, it has earned a special place in various industries, especially in construction. In this article, we will introduce you to this remarkable material with a comprehensive and practical perspective.
A Brief History
The first attempts at commercial use of PVC date back to the early 20th century. However, the rigidity and brittleness of this polymer initially hindered its widespread application. Finally, in 1926, Waldo Semon succeeded in transforming it into a flexible material by adding polymer additives, paving the way for its industrial use.
PVC Production Methods
There are five main methods used for the production of PVC, each with its unique characteristics:
Suspension Method (S-PVC): The most common method of production, covering about 80% of the global market. It is suitable for transparent products with low water absorption.
Emulsion Method (E-PVC): Performed with the help of emulsifiers, and its output is used for making artificial leather, gloves, and wallpaper.
Bulk Polymerization Method: Similar to the suspension method but with tighter control, suitable for producing specialized compounds.
Solution Method: In this method, the monomer is dissolved in an organic solvent, and the polymer is simultaneously formed in that same solvent.
Precipitation Method: Very similar to the solution method, but here, the polymer does not dissolve in the solvent and precipitates at the end of the reaction.
Types of PVC
PVC is divided into three types, each with its specific applications:
Rigid PVC (UPVC)
This type contains no plasticizers and is used in the production of pipes, window profiles, and fittings. Its main features include high resistance to pressure, impact, and environmental conditions.Flexible PVC (PVC-P)
By adding plasticizers such as DOP, this type becomes flexible. It is used in the manufacture of hoses, shoes, clothing, and packaging materials.Modified PVC (MPVC)
This type has enhanced physical and mechanical properties. It is lighter, more durable, and suitable for applications requiring high endurance.
Distinctive Features of PVC
High tensile and impact strength
Resistance to corrosion, abrasion, and scratches
Excellent thermal and sound insulation
High durability against weather conditions
Affordable and cost-effective
Resistant to UV, oils, and chemicals
High processability for manufacturing various products
Applications of PVC in Various Industries
PVC is used in both rigid and flexible forms, each with a wide range of applications across different industries.
Flexible Type
Hoses and Flexible Pipes:
Used in irrigation, household, and industrial applications with high resistance.
Soft Sheets and Films:
Applied for covering tanks, rooftops, tablecloths, and protective sheets.
Calendering:
Production of soft foils and films by passing the material through rollers.
Footwear Industry:
Used for durable soles, sandals, boots, and indoor shoes.
Plastic Cans and Parts:
Resistant to chemicals, heat, and oil.
Cable Coating:
Ideal for safe electricity transmission and resistant to environmental factors.
Floor Coverings:
Used in homes, vehicles, and public spaces.
Clothing:
Manufacture of synthetic leather (rexine) for garments, bags, shoes, and more.
Rigid Type
Water and Sewage Pipes:
Lightweight, durable, and cost-effective for fluid transmission.
Additives for Concrete and Asphalt:
Enhance mechanical strength.
Window Profiles:
An excellent alternative to wood and metal.
Credit Cards:
Durable, printable, and flexible bodies.
Interior Decorations:
PVC films for cabinets, wall panels, and false ceilings.
