Depending on the type of PVC and additives, the compound prior to gelation can be a free-flowing powder (known as a dry blend) or a liquid in the form of a paste or solution. The compound is generated by intimately mixing together the ingredients, which is subsequently converted into the gelled article under the influence of heat (and shear). The convention in recording the additive concentration is based on parts per hundred of the PVC resin (phr). PVC compounds are based on the combination of the polymer and additives that give the formulation Its durability (85% is used in medium- to long-term life span applications), linked to its cost-effectiveness, has made it the second largest commodity plastic after polyethylene. It is this scope for generating a wide range of properties through appropriate formulation that gives PVC a broad application coverage that is unmatched by any other commodity thermoplastic. Therefore, it is necessary to combine with the polymer a number of suitable additives to give a wide and varied range of properties to satisfy many different end-use applications. PVC cannot be processed on its own due to its very low thermal stability and high melt viscosity. PVC results from the polymerization of vinyl chloride (PVC COMPOUNDING & PROCESSING). Chlorine and ethylene can be combined to form the monomer, vinyl chloride (VCM). Ethylene can be derived from naphtha when oil is refined. Salt water electrolysis yields chlorine (in addition to caustic soda and hydrogen). PVC is a product based on two of the earth’s natural resources, salt and oil.
