PVC is an acronym for polyvinyl chloride. PVC resin is a material often used in the production of plastics and rubbers. PVC resin is a white powder commonly used to produce thermoplastics.
PVC can be produced in numerous forms and used to create a wide array of items for many industries. Products made with PVC resin include blood bags, windows, and pipes.
Production of PVC resin generally relies heavily on the use of chlorine and crude oil. There are four manufacturing processes commonly used in its production. They are the suspension method, the mass method, the emulsion/dispersion method, and the solution method.
PVC resin alone is a raw material. It can be made into products with a wide range of properties from soft and flexible to light and rigid. The outcome is often determined by additives. Other ingredients must typically be added to convert this resin into a finished product. These can include heat stabilizers, lubricants, and fillers. One of the most common types of additives to be blended with PVC is plasticizers, such as butyl glycolate, epoxy resins, and dialkyl azelate.
There are many benefits in plasticized PVC. Since it is a thermoplastic, meaning it can be melted down and reformed, PVC is often produced into sheets that will be reworked later. These are normally hard.
When plasticizers are added, the material tends to become much more flexible and pliable than it otherwise would be. The chemical resistance, stress resistance, and puncture resistance can also be increased. PVC in the plasticized form is extremely popular.
PVC resin generally has a high level of chemical resistance. This may not be seen, however, when the material is exposed to organic chemicals. PVC is also strong and resistant to water and abrasion. This material is very popular in the construction industry. It can be used to produce many items needed.

1. PIPES
Roughly half of the world's polyvinyl chloride resin manufactured annually is used for producing pipes for municipal and industrial applications.
2. ELECTRIC CABLES
PVC is commonly used as the insulation on electrical cables. PVC used for this purpose needs to be plasticized.
3. CONSTRUCTION
PVC is a common, strong but lightweight plastic used in construction. It is made softer and more flexible by the addition of plasticizers.
4. CLOTHING AND FURNITURE
PVC fabric is water-resistant, used for its weather-resistant qualities in coats, skiing equipment, shoes, jackets, aprons, and sports bags.
