A thermoplastic vinyl chloride polymer composition superior in processing properties is provided.
Vinyl chloride polymer 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.
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.
A thermoplastic or thermosoftening plastic is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling.
Pvc is a 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.
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.
These linear polymers are said to be 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.
Pvc can be rigid or flexible clear or opaque.
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 comes in two basic forms.
Of component a polymerized from.
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.
Polyvinylchloride pvc or vinyl is a thermoplastic and the third largest production polymer in the world.
Vinyl chloride resin of an average degree of polymerization of 700.
