What are the applications of PVC?

PVC is a versatile material that offers many possible applications, these include; window frames, drainage pipe, water service pipe, medical devices, blood storage bags, cable and wire insulation, resilient flooring, roofing membranes, stationary, automotive interiors and seat coverings, fashion and footwear, packaging …

What is PVC compound used for?

The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used in making bottles, non-food packaging, food-covering sheets, and cards (such as bank or membership cards).

Why is PVC used in chemical industries?

In terms of revenue generated, PVC is one of the most valuable products of the chemical industry. There are many uses for PVC. As a rigid plastic, it is used as vinyl siding, magnetic stripe cards, window profile, pipe, plumbing and conduit fixtures. PVC is commonly used as the insulation on electric wires.

What is PVC chemistry?

PVC is Polyvinyl Chloride. This is a plastic that has the following chemical formula: CH2=CHCl (see picture on the right).

Why is PVC used in medical applications?

PVC is widely used in medical applications today because it’s impermeable to germs, is easily cleaned and provides single-use applications that reduce infections in healthcare. PVC has been used in the medical realm for more than 50 years.

Why is PVC plasticized?

PVC had been prepared as early as 1872, but commercial application of the polymer was limited by its extreme rigidity. Then in 1926 Semon, while trying to dehydrohalogenate PVC in a high-boiling solvent in order to obtain a rubbery polymer that might bond to metal, produced what is now called plasticized PVC.

Why is PVC generally plasticized?

Industries such as plumbing, sewage, and agriculture can utilize rigid PVC across many functions. Flexible, plasticized, or regular PVC is softer and more amenable to bending than uPVC due to the addition of plasticizers like phthalates (e.g., diisononyl phthalate or DINP).

Why is PVC used for medical applications?

How PVC is prepared what are its uses?

PVC is produced by polymerization of vinyl chloride monomer (VCM). The PVC is separated off and dried to form a white powder also known as PVC resin (see flow diagram). Emulsion polymerization produces finer resin grades having much smaller particles, which are required by certain applications.

Is a example of PVC?

It is made up of 57% chlorine and 43% carbon. A thermoplastic is known to be polyvinyl chloride (PVC). Thus, we can say PVC is an example of thermoplastic.

How are plastics used in medicine?

Plastics have been used widely to create medical tools and devices like surgical gloves, syringes, insulin pens, IV tubes, catheters, inflatable splits, etc. Such products are created for one-time use and help prevent the spread of dangerous diseases by eliminating the need to sterilize and re-use a device.

What are the uses of polyvinyl chloride ( PVC )?

Polyvinyl Chloride (PVC or Vinyl) is a high strength thermoplastic material widely used in applications, such as pipes, medical devices, wire and cable insulation…the list is endless. It is the world’s third-most widely produced synthetic plastic polymer. So, what is PVC? What it is made up of?

How does plasticizer affect the properties of PVC?

By changing type and amount of plasticizer, properties can be tailored to requirements. Increasing plasticizer concentration increases flexibility, decreases tensile strength, and reduces hardness (e.g., Figure 1 ). PVC itself does not readily burn, but the addition of plasticizer increases flammability.

What kind of polymers can a plasticizer be used for?

However, a significant amount of plasticizers are also used in polymers like acrylics, PET, polyolefins, polyurethanes, etc. Plasticizers are also sometimes used in rubbers but in these cases they are used as extenders. A polymer can be internally plasticized by chemically modifying the polymer or monomer so that the flexibility is increased.

What are the different types of PVC plastic?

But, there are more types like CPVC, PVC-O and PVC-M. Plasticized or Flexible PVC (Density: 1.1-1.35 g/cm 3 ): Flexible PVC is formed by the addition of compatible plasticizers to PVC which lower the crystallinity. These plasticizers act like lubricants resulting in a much clearer and flexible plastic.
