Significance of PVC in the Indian Petrochemical Sector

Manufacturing of polyvinyl chloride (PVC) in India started 60 years ago together with the country's very first PVC plant set up in Mumbai in 1951. The plant operated by Calico had a capacity of 6000 mt/year. At present, the Indian PVC sector boasts of a production capacity of 1.3 million mt/year.

In India, Chemplast Sanmar, DCM Shriram Consolidated, DCW, Finolex and Reliance Industries have been creating PVC. The most recent entrant in to the Indian PVC market place will be the Vivanta group, whose 240,000 mt/year PVC plant started operations in 2013.

PVC, certainly one of the oldest forms of commodity polymers, is these days regarded as an infrastructure plastic and finds a variety of infrastructure applications, for example in pipes, ducts, wires, cables, floorings, windows and roofing. Moreover, the usage of PVC in other sectors for instance automobiles, medical and healthcare, packaging and sports and leisure can also be increasing.

PVC is actually a thermoplastic composed of 57% chlorine and 43% carbon. It truly is significantly less dependent than other polymers on crude oil or all-natural gas, that are non-renewable, and hence PVC is usually regarded as a natural resource saving plastic. Even though PVC can be made from a variety of hydrocarbons including coal, the bulk with the world's PVC is presently manufactured making use of ethylene, which is combined with chlorine to make ethylene dichloride (EDC), the raw material for the manufacture of vinyl chloride monomer (VCM). VCM is further polymerized to make PVC. PVC is also created utilizing calcium carbide, that is widely prevalent in China.

In line with Chemical Advertising Associates Inc. (CMAI), the worldwide consumption of PVC in 2010 was 34.8 million mt from an general capacity of 46 million mt, and accounted for 18% of the total consumption of polymers. The global demand for PVC is estimated to rise to 44 million mt and the international PVC capacity is anticipated to rise to 55 million mt by 2015.

Based on business sources in India, the country's PVC demand is at present pegged at two.08 million mt/year and also the capacity is pegged at 1.33 million mt/year. The consumption of PVC in India is anticipated to enhance to three.1 million mt/year by 2016-17 plus the nation's PVC capacity is anticipated to rise to 1.63 million mt/year. As is evident from the above-mentioned demand and supply numbers, PVC demand is anticipated to exceed supply.

Pipes
Pipes have already been the biggest end-use sector for PVC using a share of about 70%. The usage of PVC in pipes benefits in energy saving at all stages from the life cycle of a pipe, namely, extraction of raw materials, production, transportation, usage and recycling. In addition to saving energy, PVC pipes also help protect environment by minimizing CO2 emissions. With an investment of Rs. 20 lakh crore towards infrastructure improvement in India in 2011-12 as well as a projected investment of Rs. 40 lakh crore till 2016-17, the consumption of PVC in pipes is expected to progressively enhance and attain ten million mt by 2017 from a current estimated consumption of six million mt. Moreover, energy savings from applying PVC in pipes would amount to 51.6 million MWh by 2016-17 from an estimated 31.4 million MWh savings at present and 16 million MWh savings inside the period 2002 to 2007. Likewise, reduction in CO2 emissions would quantity to 182 million mt by 2016-17 from 57.7 million mt in 2006-07 and an estimated 110.6 million mt at present.




PVC pipes have the following advantages over ductile iron (DI) and galvanized iron (GI) pipes:

• Light in weight and straightforward to install.
• Non-corrosive.
• Exhibit a low coefficient of friction.
• Additional resistant to abrasion than DI or GI pipes.
• Exhibit a low thermal conductivity.
• Exhibit flexibility and biological resistance.
• Non-toxic and maintenance-free.
• Exceptional jointing techniques.

It is estimated that in India, PVC usage in pipes will reach 9,790 kt by 2017 from an estimated present consumption of 6,000 kt.

Windows

PVC has come to be a well known material for window and door frames and PVC windows are being preferred more than the standard aluminum windows owing for the following benefits of PVC more than aluminum and wooden windows:

• PVC windows offer fantastic thermal insulation as PVC can be a poor conductor of heat.
• PVC windows are noise-proof, dust-proof and monsoon-proof.
• Power savings might be realized through all of the stages with the life cycle of PVC windows.
• PVC windows exhibit durability and extended life. As per British Plastics Federation, the life expectancy of a PVC window is more than 40 years.
• PVC windows exhibit design and style flexibility and versatility and are effortless to fabricate and set up.
• Windows produced of PVC are fashionable, sophisticated and aesthetically pleasing.
• PVC is often recycled somewhat straightforwardly.
• PVC windows can save up to 30% of electrical energy expenses.

The reputation of PVC windows is rising in India, especially in important metro cities. From significantly less than 1.5 kt in 2002-03, the consumption of PVC in windows enhanced three occasions to 4.six kt in 2006-07. During the present fiscal year, the consumption is estimated to reach 26 kt. Furthermore, the truth that the improvement concentrate has now shifted to Asia has led world-renowned window producers to set up their fabrication units in India and by 2016-17, the consumption of PVC in window profiles is estimated to attain 205 kt.

PVC scenario in India

PVC capacity growth in India in the past has been substantially lagging behind demand development. PVC demand within the nation is escalating at approximately 10%, that is far more than twice in comparison with the globe average of 4%. Having said that, for the consumption of 1.9 million mt/year, pretty much 600 kt/year is becoming imported from unique components on the globe. Regardless of the substantial PVC capacity addition by Chemplast Sanmar, from 30 kt to 250 kt, the gap amongst demand and provide of PVC within the country is anticipated to widen for the duration of 2012-2017. Heavy investments by the government in infrastructure projects and concentrate on increase in irrigational land are the most important drivers for the improved consumption of PVC. In addition, the introduction with the eco-point program for housing and funding by various International Agencies like Globe Bank and Asian Improvement Bank for water management projects inside the nation will give major increase to the PVC decorative sheet.

Hence, it can be said that a large-scale PVC plant in India is really a promising venture offered that it is actually furnished with competitively priced energy and adequate provide of chlorine and ethylene.
