Vinyl Chloride Polymer Thermoplastic

Pvc is a thermoplastic.

Vinyl chloride polymer thermoplastic.

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. 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. Polyvinylchloride pvc or vinyl is a thermoplastic and the third largest production polymer in the world. A thermoplastic vinyl chloride polymer composition superior in processing properties is provided.

Vinyl chloride resin of an average degree of polymerization of 700. It is one of the most analyzed tested and versatile materials on the market. 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. These linear polymers are said to be thermoplastic.

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. 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. Rigid sometimes abbreviated as rpvc and flexible. 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. A thermoplastic or thermosoftening plastic is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. Of component a polymerized from.
