Vinyl Chloride Polymer Thermoplastic

Polyvinylchloride pvc or vinyl is a thermoplastic and the third largest production polymer in the world.

Vinyl chloride polymer thermoplastic.

Polyvinyl chloride pvc is a linear polymer and like most linear polymers the application of heat and pressure will cause it soften and take on new shapes. Most thermoplastics have a high molecular weight the polymer chains associate by intermolecular forces which weaken rapidly with increased temperature yielding a viscous liquid in this state thermoplastics may be reshaped. Thermoplastic moulding materials for the production of packaging materials for foodstuffs which consist of or are based on vinyl chloride polymers and contain monoalkyl tin stabilizers. Pvc is a thermoplastic.

A thermoplastic vinyl chloride polymer composition superior in processing properties is provided. Rigid sometimes abbreviated as rpvc and flexible. It is one of the most analyzed tested and versatile materials on the market. 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.

The composition comprises i a predominant amount of polyvinyl chloride or a copolymer predominantly comprised of vinyl chloride and ii a minor amount of two stage sequentially produced methyl methacrylate composite polymer consisting essentially of 1 to 49 wt. These linear polymers are said to be thermoplastic. To obtain the title composition decreased in a compression set improved in processability and tensile strength and usable as a substitute for a vulcanized rubber by reacting a vinyl chloride resin with a nitrile rubber a plasticizer and a curing agent by kneading at a specified temperature. Pvc can be rigid or flexible clear or opaque.

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. Pvc comes in two basic forms. Vinyl chloride resin of an average degree of polymerization of 700.
