What Is The Density Of Pvc Vinyl
Polyvinyl chloride pvc a major plastics material which finds widespread use in building transport packaging electrical electronic and healthcare applications.
What is the density of pvc vinyl. Flexible pvc is formed by the addition of compatible plasticizers to pvc which lower the crystallinity. When treated with certain catalysts vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride or pvc. Actually the mass of an object is referred to its weight. And the si unit is kg m3.
It is important to note that density varies with temperature. Vinyl composition tile vct is a finished flooring material used primarily in commercial and institutional applications. Always there is confusion in people between mass and weight. 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.
Pvc is chemically stable and does not de polymerize density. Pvc is used in the manufacture of numerous products including packaging films and water pipes. Polyvinyl chloride is widely available in two broad categories. Pvc is a very durable and long last construction material which can be used in a variety of applications either rigid or flexible white or black and a wide range of colours in between.
Density measures the mass per unit volume it is calculated by dividing the mass of the material by the volume and is normally expressed in g cm 3. It is also readily available and very economical which combined with the long lasting characteristics of most plastics make it an easy choice for many industrial applications like construction. Pvc vinyl chloride is an organohalogen compound that has important industrial applications. Environmental impact and occupational health and safety aspects of pvc.
Vinylidene chloride vinyl chloride copolymer 5 vinyl chloride. Rigid sometimes abbreviated as rpvc and flexible. These plasticizers act like lubricants resulting. What is density of plastic.
Therefore to determine the exact density of plastic it is. Manufacture of pvc the manufacturing plastics often creates large quantities of toxic chemical pollutants such as dioxin hydrochloric acid and vinyl chloride. The density of a plastic sample may change due to change in crystallinity loss of plasticizers absorption of solvent etc. Pvc comes in two basic forms.
But there are more types like cpvc pvc o and pvc m. Plasticized or flexible pvc density. Rigid pvc in particular has very high density for a plastic making it extremely hard and generally very strong.
