Question

PVC is an example of
a.) Polyethene
b.) Thermoplastic
c.) Thermosetting plastic
d.) Acrylic

Answer 1

Before approaching the solution of the question, one should have prior knowledge about the PVC and what type of compound it is and also remember that PVC is made of 57% of chlorine and 43% of carbon, using this information you can approach the solution of the question.

Complete step by step answer:
PVC, made entirely of polyvinyl chloride, a synthetic resin made of vinyl chloride polymerization. It is available in powder form or granules as a white, brittle solid material. PVC is now replacing conventional building materials such as wood, metal, concrete, rubber, ceramics, etc. in many applications, due to its flexible properties, such as lightweight, robust, low cost and simple thermal stability. PVC is a material that is very flexible and cost-effective. Its key properties and advantages include:

Electrical Properties: Thanks to its high dielectric strength, PVC is a successful insulation material.
Durability: PVC is weather resistant, resistant to chemical rotting, corrosion, abrasion and shock.
Flame Retardancy: PVC goods are self-extinguishing due to their high chlorine content. Its index of oxidation is 45. Antimony trioxide, typically in conjunction with phosphate ester plasticizers, has been used extensively, offering excellent fire efficiency and mechanical properties.
Cost / Performance Ratio: PVC has good physical as well as mechanical properties and shows outstanding benefits in terms of cost-performance. It has a long lifespan and has low maintenance.
Mechanical properties: PVC is resistant to abrasion, light and tough.
Chemical Resistance: PVC is resistant to all contaminants that are inorganic. Its tolerance to diluted acids, diluted alkalis and aliphatic hydrocarbons is very strong. Attacked by ketones, swollen or attacked in certain grades by chlorinated and aromatic hydrocarbons, esters, aromatic ethers and amines, and nitro-compounds.

Chemical composition of PVC is (${C_2}{H_3}Cl{)_n}$. It is made up of 57% chlorine and 43% carbon. A thermoplastic is known to be polyvinyl chloride (PVC). Above a particular temperature, thermoplastics become moldable and then revert to a solid when cooled. Thermoplastics are known for their high molecular weight because intermolecular interactions increase as the plastic is cooled.
Thus, we can say PVC is an example of thermoplastic.
So, the correct answer is “Option B”.

Note: In the above answer we used the term “polyvinyl chloride” which is used economically in a variety of applications in the buildings and construction, health care, automobile, electronics, and other sectors, in products ranging from piping and siding, blood bags and tubing, to wire and cable insulation.
