Vinyl Chloride Polymer Thermoplastic

Of component a polymerized from.

Vinyl chloride polymer thermoplastic.

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 the world s third most widely produced synthetic plastic polymer after polyethylene and polypropylene about 40 million tons of pvc are produced each year. 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. A thermoplastic vinyl chloride polymer composition superior in processing properties is provided.

It is one of the most analyzed tested and versatile materials on the market. Pvc is a 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. Rigid sometimes abbreviated as rpvc and flexible.

These linear polymers are said to be thermoplastic. Polyvinyl chloride pvc or vinyl is an economical and versatile thermoplastic polymer widely used in building and construction industry to produce door and window profiles pipes drinking and wastewater wire and cable insulation medical devices etc. Polyvinylchloride pvc or vinyl is a thermoplastic and the third largest production polymer in the world. A thermoplastic or thermosoftening plastic is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling.

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. Vinyl chloride resin of an average degree of polymerization of 700. 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.
