PPS is available in a variety of grades that are appropriate for fluidized-bed coating, slurry coating, electrostatic spraying and injection, and compression molding. PPS is of two types, recycled PPS and virgin PPS. Recycled PPS has a lower price than virgin PPS. Recycled PPS has inferior properties and higher impurities than virgin PPS. Though recycled PPS offers advantages such as cost savings to end-use industries, it is subject to environmental regulations. Thus, there is growing demand for virgin PPS in various end-use industries including automotive, electrical and electronics, filter bag and others. These industries prefer virgin PPS to recycled PPS as using the former involves lower environmental risks.

Polyphthalamide (PPA) is a semi-crystalline synthetic resin of nylon, commonly known as high-performance polyamide. PPA exhibits superior performance in hightemperature applications such as high-temperature cooling lines, engine cooling, nonhalogenated connectors, and in turbocharged air systems for air management applications. It is largely used in automobile and industrial applications to replace the metal components. PPA possesses ultra-high strength and temperature resistance in comparison with the metal components. In addition, PPA is also preferred due to its lightweight characteristics.

Polystyrene (PS) foam was initially used as a rubber replacement and as a coating to protect metal, wood, and other similar materials. However, with the invention of polyurethane (PU), the scope of application of polymer foam extended to the furniture and automotive industries. The invention of injection molding, twin screw foam, and other extrusion techniques led to a further increase in the spectrum of applications in which it can be used.

Polyacrylamide is an acrylic resin compound that is soluble in water. It is generally produced by the polymerization of acrylamide monomer subunits. Acrylamide is an odorless and colorless, water-soluble chemical compound. It is produced by the hydration of acrylonitrile and is commonly used in the synthesis of polyacrylamide polymers. Generally, acrylamide polymer is non-hazardous, but its monomer can affect the respiratory and nervous systems. Acrylamide is classified as a probable human carcinogen by the International Agency for Research on Cancer (IARC) and Environmental Protection Agency (EPA).

Pneumatic seals are used in pneumatic components like cylinders and valves that are used in applications that involve rotary or reciprocating motions. The seals are used in devices or components that work in low pressure. Minimal lubrication is used in pneumatic seals to ensure a tight seal so that they can be used in devices or components that are exposed to high operating speeds at low pressure. The pressure range of pneumatic seals ranges between 1 and 150 pound-force psi.

Semiconductor intellectual properties (SIPs) are considered to be the building blocks or reusable design core components of chip design layout, which are either created by the users for their own use and/or licensed to other users. Physical IPs are referred as the design of building blocks used in the development of SoCs. Physical IPs, which include analog and mixed signal, memory cells, wired interface, wireless interface, and physical library accounted for a revenue share of 32.05% in the global semiconductor IP market.

The pharmaceutical industry worldwide witnesses a dramatic regional shift to the pharmerging market, owing to the opportunities available. Considering the on-going trend of shift in global medicine dosage consumption to developing countries, about 55-60% of global consumption should come from pharmerging markets by 2021. This will eventually lead to an incremental growth of around 25% from 2016 level.
