Poly Vinyl Chloride Structure

Pvc is used in the manufacture of numerous products including packaging films and water pipes.

Poly vinyl chloride structure.

A highly versatile polymer pvc is compatible with many additives. 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. Vinyl chloride is an organohalogen compound that has important industrial applications. Poly vinyl chloride is the plastic known at the hardware store as 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. Rigid sometimes abbreviated as rpvc and flexible. Polyvinyl chloride processing and structure 603 2 2 1 extrusion of plasticized pv processing is unproblematic even in the case of higher filled recipes up to 50 vol mineral powder can be applied as the viscosity of the melt is already low enough at about 175 c and the heat of shear remains insignifigant. 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. This is the pvc from which pipes are made and pvc pipe is everywhere. Vinyl chloride is primarily used to make polyvinyl chloride to manufacture plastics. Effect of hydrogenation and chlorination reactions on the β relaxation of poly vinyl chloride journal of macromolecular science part b.

Pvc comes in two basic forms. 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 the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year. Polyvinyl chloride pvc has become a universal polymer with many applications e g for pipes floor coverings cable insulation roofing sheets packaging foils bottles and medical products because of its low cost and physical chemical and weathering properties.
