Where Can I Get A Polymer Of Vinyl Chloride
In the past vinyl chloride could get into food stored in materials containing pvc but the u s.
Where can i get a polymer of vinyl chloride. Kanevinyl m series which is a vinyl chloride vinyl acetate copolymers has outstanding fluidity in its molten state and is suited to processing at low temperatures. When less than about 1 ppm of vinyl chloride is trapped in pvc packaging vinyl chloride in detectable amounts does not enter food by contact with these products. It also has excellent stretch properties at high temperature making it ideal as a material for secondary processing such as vacuum molding. Vinyl chloride is an alkene derivative containing a substituted chlorine atom instead of a hydrogen atom.
Vinyl chloride monomer left 3 and polymer right 4 one method for producing vinyl chloride is to first produce dichloroethane c 2 h 4 cl 2 by chlorinating ethene c 2 h 4 dichloroethane is heated and decomposed in a process known as thermo cracking to form vinyl chloride monomer c 2 h 3 cl and. Vinyl chloride is an organochloride with the formula h 2 c chcl that is also called vinyl chloride monomer vcm or chloroethene this colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc. Chloride is highly flammable 4 toxic 2 and reactive 2 2. This is a linear polymer.
Due to the hazardous nature of vinyl chloride to human health there are no end products that use vinyl chloride in its monomer. It can be used either as a base. 5 18 60 61 these polymers have been used extensively in the past for corrosion protective systems but they often need large amounts of strong solvents to be apply properly. Government now regulates the amount of vinyl chloride in food packaging materials.
Pvc comes in two basic forms. About 13 billion kilograms are produced annually. Polyvinyl chloride ˌ p ɒ l i v aɪ n əl ˈ k l ɔːr aɪ d. Vinyl chloride is a chemical intermediate not a final product.
Vinyl polymers is a name often used to identify polymers based on the vinyl group nch ch 2 but really has been used to identify polymers and copolymers of vinyl chloride. 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. Vinyl chloride monomer vcm other names chloroethylene is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride pvc.
