PVC, or polyvinyl chloride, is one of the most famous polymers in the world, second only to polyethylene and polypropylene. This material is also known by other names: vinyl, vinol and hostalite.
Almost all vinyl chloride used in industry is recycled into PVC. The history of this plastic began in 1835, when scientist Henri Regnault discovered the main component of vinyl. Almost 40 years later, another German scientist, Bauman, accidentally obtained vinyl chloride from several components. It’s amazing how sometimes accidents can change the course of history. One day, a German specialist forgot to remove the base solution from the windowsill, and under the influence of high temperature it dissolved. This is how a new polymer was discovered and has since been used in almost all areas of production, at enterprises and in everyday life.
From the point of view of chemistry, PVC (polyvinyl chloride) consists of monomeric chains of ethylene chloride, which form strong bonds with each other. The degree of polymerization may vary depending on the type of PVC. According to its chemical structure, PVC is an amorphous polymer. This provides it with high strength, heat resistance and resistance to aggressive environments.
PVC is a unique and versatile material that finds application in a wide variety of fields. By changing the chemical composition, various types of polymers can be obtained: soft, hard, durable and transparent. PVC can withstand temperatures from -80 to +110 degrees Celsius. It can be synthesized in various ways, usually using a basic composition based on chlorine and refined petroleum products in a ratio of 57% to 43%.
PVC has a number of advantages that make it a valuable material:
• high mechanical strength (not only compared to other polymers);
• almost complete absence of moisture absorption;
• minimal stretching;
• Excellent insulation properties (used to insulate appliances);
• Damage resistance;
• High resistance to high and low temperatures.
In addition, PVC tolerates contact with various alkalis, saline solutions and weak acids well.
It is difficult to find another material that would have such universal properties and characteristics. Of course, PVC has its drawbacks. For example, it may lose some of its properties when exposed to sunlight. Compared to natural wood, PVC weighs a little more, although it can withstand heavy loads.
PVC is a great plastic, but it’s not perfect. However, all its disadvantages are easily offset by advantages such as efficiency, low cost and a wide range of applications.
The most popular plastic in the world is used in all spheres of human activity. Window profiles, wall panels and other finishing materials, disposable syringes, packaging materials, medical equipment and much more — all this is made of PVC
