What are the properties of polyvinyl chloride?

Flexible PVC

  • Low cost, flexible & high impact strength.
  • Good resistance to UV, acids, alkalis, oils and many corrosive inorganic chemicals.
  • Good electrical insulation properties.
  • Non-flammable & versatile performance profile.
  • Easier to process than rigid PVC.

Is polyvinyl chloride a solid liquid or gas?

In this form, it is also used in plumbing, electrical cable insulation, imitation leather, flooring, signage, phonograph records, inflatable products, and many applications where it replaces rubber. With cotton or linen, it is used in the production of canvas. Pure polyvinyl chloride is a white, brittle solid.

Which gas is used in PVC?

The combination of chlorine and ethylene to make the vinyl chloride monomer (VCM) The polymerisation of VCM to make poly-vinyl-chloride (PVC) The blending of PVC polymer with other materials to produce different formulations providing a wide range of physical properties.

Does PVC off gas?

PVC is useless without the addition of many toxic additives, which can make the PVC product itself harmful to consumers. These chemicals can evaporate or leach out of PVC, posing health risks to children and consumers (off-gassing). The new car or shower curtain smell is that of chemicals off-gassing from the PVC.

Is PVC flammable?

PVC (polyvinyl chloride) pipe is not considered flammable. PVC has an ignition temperature of 734 degrees Fahrenheit (390 degrees Celsius) to catch fire.

Is polyvinyl chloride soluble?

It is soluble in a few organic solvents, such as tetrahydrofuran, and is swollen to varying extents by polar solvents such as ketones and esters, and by aromatic and chlorinated hydrocarbons. It is essentially unaffected by aliphatic hydrocarbons and oils.

How is plastic made from gas?

Plastics are made from raw materials like natural gas, oil or plants, which are refined into ethane and propane. Ethane and propane are then treated with heat in a process called “cracking” which turns them into ethylene and propylene. These materials are combined together to create different polymers.

Is PVC chemically inert?

PVC is completely non-toxic and inert, which means that it can be applied to medical and hospital products, food and toy films; provided that the additives also possess these characteristics, obviously.

What gas is released when PVC is burned?

All organic materials, whether they are natural or synthetic, produces toxic gases during combustion. The most important gases from PVC when burning is carbon monoxide, carbon dioxide, hydrogen chloride and water. Chlorine gas never develops from PVC fires.

Does PVC off gas when heated?

Building Fires and PVC Although PVC is flame resistant, PVC products release toxic hydrogen chloride gas when heated. These corrosive gases can spread faster than flames, trapping building occupants before they have a chance to escape. Hydrogen chloride gas is lethal when inhaled.
