The market studied is expected to grow significantly in the future, majorly driven by the expansion of polymer resin production. Polymers are widely used in applications, such as injection molding, blow molding, and others, across various end-user industries, including electrical and electronics, automotive, construction, medical, and consumer. The market studied is significantly influenced by the increasing trends in the automotive industry, such as lower emissions, increasing demand for lighter vehicles, fuel efficiency, and other factors. In addition, the rising number of electrical vehicles around the world, particularly in the Asia-Pacific region, has boosted the demand for polymer resins. The demand for packaged products has also increased over the recent years, which is further propelling the demand for polyolefins. The increased use of plastic as a substitute for glass and metal products, the development of new products, and an increased level of sophistication in plastic processing methods are some of the major factors that have led to the expansion of polymer and resin production in these industries. Many countries in the Asia-Pacific region, par ticularly China and India, are expanding their polymer resin production levels, in order to reduce their dependency on imports.

Polyphenylene sulfide (PPS) is a high-performance, opaque, thermoplastic material. It is known for high resistance to heat, burning, and chemicals, and has good electrical proper ties. Most commercial grades are glass-fiber reinforced. Others contain mineral filler, carbon, or PTFE. The following values are based on 40% glassreinforced PPS, which is the most frequently used. Owing to its various properties (as mentioned in the next slide) it is used in many applications, such as electrical/electronic applications, automotive applications, industrial applications, appliances, general purpose, electronic displays, bearings, pump parts, appliance components, and electrical parts. Moreover, PPS is considered an alternative matrix amongst the cheapest commodities and high-performance polymers, e.g. polyarylether ketone, polyether ether ketone, and polyamide. Composites made up of PPS are used for many applications, like production of plug boards, coil formers, chip carriers, automotive main parts, connectors, switches, relays and medical applications, etc.

Fibers are a source of reinforcement in engineering polymer composites, responsible for strength and stiffness. As in composites, stress is transferred from fiber to polymer and vice versa, and high mechanical properties are only acquired if appropriate compatibility exists between the matrix and reinforcement. The aviation industry generates around 2-3% of all human-induced Co2 emissions and 12% of the emissions of the transportation industry. The higher consumption of fuel in the aircraft leads to larger emissions of greenhouse gases and contributes to global warming. Moreover, the higher level of fuel consumption leads to higher cost, thus, increasing the operational cost of airlines. The aerospace industry is constantly focusing on producing fuel-efficient, lighter, yet stronger materials. Thus, the industry has shifted from using aluminum, steel, and titanium to composites. Currently, the use of composites has reduced around 50% of the structural weight of the aircraft, thus, increasing the fuel efficiency to around 20% and reducing the noise by around 5%, as well as decreasing the maintenance cost by around 30%.

Graphene, the first 2-D carbon material in the world, also known as the "wonder material," is well suited for many applications. Graphene is resistant to fire, an effective conductor, extremely versatile and 200 times stronger than steel and a substance of ultra-lightness. In addition, graphene is regarded in the chemical industry as an effective catalyst because of its properties such as high surface area and adsorption power. Growing demand for chemicals worldwide is expected to increase graphene demand and thus, drive the growth of the global graphene industry. The report on graphene exclusively focuses on current market trends and future growth opportunities of various types of graphene such as mono-layer & bi-layer graphene, few layer graphene, graphene oxide, and graphene nano platelets. Based on application, the market is divided into RFID, composites, sensors, research & development, energy storage, functional ink, and polymer additives. Based on region, it is studied across North America, Europe, Asia-Pacific, and LAMEA.

Extruded polystyrene (XPS) is a polystyrene foam obtained through the extrusion process. XPS systems use air as an insulating material and form a closely packed structure, which exhibits excellent moisture-resistant properties. The manufacturing process of XPS includes melting of polystyrene, which is then fed into an extruder along with special additives & blowing agents. Moreover, the efficiency of an insulation XPS system depends on its thickness and installation. The global extruded polystyrene insulation materials market is driven by the growth in demand for energyefficient buildings from the non-residential and residential segments of the construction industry, and rise in government infrastructure projects. However, certain environmental issues related to the use of global warmingcausing toxic chemicals like fluorochlorohydrocarbons and presence of high number of substitutes are expected to hinder the market growth during the forecast period. Manufacturers have made heavy investments to eliminate the use of these toxic chemicals and develop safer XPS systems. The introduction of high-quality, energy-efficient XPS systems and frequent product launches by market players to enhance their product portfolio provide lucrative growth opportunities for market expansion. In addition, the volume and revenue of the market is provided in the report in terms of kilotons and $million.

Phosphoric acid serves as a popular ingredient in sodas, precisely in cola drinks. Along with its aptitude to preserve the integrity of the soda's recipe blend, the ingredient drastically reduces the bacterial growth while infusing the exceptional tangy taste to the cola soft drinks, fostering its desirability amongst food manufacturers. Despite rising concern against the detrimental attributes of soft drinks, the sector lays vast scope for the niche ingredients like phosphoric acid, pertaining to robust consumption share of cola-drinks in the overall soft drink industry. According to the Beverage Digest, the companies PepsiCo and Coca Cola together constituted about 68% of total carbonated soft drink market share, in the United States, in 2018. Since the companies primarily offer cola based soft drinks, the statistic portrays promising application of phosphoric acids in the end-product. Moreover, companies in order to promote their products and supplement their sales are constantly emphasizing on the fact that phosphorus acid when taken in small quantities causes no harm. For instance, Pepsi, in response to several epidemiological studies, stated a research finding about health-effectiveness of phosphoric acids. Additionally, companies like Coca-Cola are even comparing the incorporated phosphorus content with food products, including milk, rice, chicken, to gain consumer ’s confidence.
