Poly Vinyl Chloride Structure

Pvc comes in two basic forms.

Poly vinyl chloride structure.

Vinyl chloride is a chlorinated hydrocarbon occurring as a colorless highly flammable gas with a mild sweet odor that may emit toxic fumes of carbon dioxide carbon monoxide hydrogen chloride and phosgene when heated to decomposition. Effect of hydrogenation and chlorination reactions on the β relaxation of poly vinyl chloride journal of macromolecular science part b. Poly vinyl chloride is the plastic known at the hardware store as pvc. Rigid sometimes abbreviated as rpvc and flexible.

Pvc degrades at relatively low temperatures 100 c. When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc. Second only to pe in production and consumption pvc is manufactured by bulk solution suspension and emulsion polymerization of vinyl chloride monomer using free radical initiators vinyl chloride ch 2 chcl is most often obtained by reacting ethylene with oxygen and hydrogen chloride over a copper catalyst it is a carcinogenic gas that must be handled with. This is the pvc from which pipes are made and pvc pipe is everywhere.

A highly versatile polymer pvc is compatible with many additives. The plumbing in your house is probably pvc pipe unless it s an older house. The symbol for polyvinyl chloride developed by the society of the plastics industry so that items can be labeled for easy recycling is. Pvc is used in the manufacture of numerous products including packaging films and water pipes.

Pvc is the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year. It can be plasticized to make it flexible for use in flooring or unplasticized pvc u for use in building applications and window. Vinyl chloride is an organohalogen compound that has important industrial applications. Poly vinyl chloride polyvinyl chloride pvc is one of the worldwide plastic used due to the inherent properties such as durability corrosive resistance low cost and high performance made pvc a versatile polymer with several applications for instance pipes profiles flooring cable insulation roofing packaging bottling and the medical applications.
