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.

Honeycomb sandwich is a structure with three layers, which offers high strength, stiffness, corrosive resistance, minimum raw material requirement. Increase in space and aviation activities across the world drives the market growth. These materials are widely used in the construction, automotive, and marine industries, as these provide remarkable mechanical properties and are lightweight, thus conserving fuel and reducing the weight of the marine vehicle. However, capital-intensive nature due to high cost of production and raw materials hampers the growth of the honeycomb sandwich material market. Meanwhile, 3D printing of honeycomb panels is expected to provide lucrative opportunities to the honeycomb material manufacturers.

Increasing security concerns in almost all the nations across the world is a major driving factor for long fiber in the defense sector. This, coupled with rising threats from various anti-social organizations for countries, such as the United States, India, etc., is further driving the demand for the market studied in the defense sector. Conventionally, thermoset-based composites are used as alternatives for various structural metal-based parts in military equipment manufacturing. In defense applications, fiber-reinforced thermosets are well known composite structures. However, thermoset materials have limitations, like resistance to hydrolysis and poor structural performance in fire regardless of their good flammability resistance when compared with that of thermoplastics. The above-mentioned factors are quite instrumental in impacting on the consumption of thermosets, which are ultimately going to drive the growth prospects of the thermoplastics market over the forecast period.

Liquid crystal polymer (LCP) is a super engineering plastic, with a combination of high strength, modulus and impact proper ties, flame retardance, resistance to a wide range of aggressive chemicals, very low and tailorable coefficients of thermal expansion (CTE), excellent dimensional stability, thin-wall flowability, and unique processability. This balance of characteristics is the main reason for electrical and electronics applications to have one of the major commercial end uses for these thermoplastics. With the miniaturization trend of many electronic products,manufacturers are streamlining devices to pack more features into smaller packages. For instance, the pitch (spacing) between contacts in electrical connectors is narrower than ever before, and as small as 0.2 mm, when compared to older-style power connectors, with pitches exceeding 12.0 mm. Nominal wall stocks have also thinned considerably, as the overall size of connectors has shrunk. These thin-wall designs pose a challenge during the injection molding of micro connectors for devices, such as iPads, robots, computers, cell phones, and satellites. A suitable material must withstand reflow soldering without distor ting, melting, or blistering, and (LCPs) prove to be the much-needed ticket when compared to other traditional polymers. For the same reasons, LCPs are also injection molded into integrated circuit (IC) sockets, high-frequency (HF) network switches, power modules for wind and solar inverters and converters, custom high-power electrical connectors, and many other precision devices.

SiC fibers are manufactured with the help of pyrolysis of organosilicon polymers, such as polycarbosilane. Another method for the production of SiC fibers is the use of the CVD (chemical vapor deposition) method. High strength along with a lightweight, stability over high temperature, and resistance from oxidation and corrosion make it an ideal material to be across various ends use industries such as aerospace and defense, power and energy, chemical, automotive, and others. The rising focus towards the advancement of the performance of commercial and military aircraft is continuously driving the demand for high performance structural materials in the aerospace industry. Composite materials have gained acceptance for aviation and aerospace applications owing to exceptional strength coupled with superior physical properties and stiffness-to-density ratios. The aerospace industry is considered as the prime user of SiC fibers. The use of SiC fibers is important for application dealing in extreme mechanical loads at high temperatures (up to 1900 K in the air) and cannot be met out with any metallic material or intermetallic materials. Another most significant application field of silicon carbide composites relates to the manufacturing of such materials in spacecraft, which could possess lightweight and thermo-mechanical properties at the same time and could bear high temperatures. They are also used to manufacture thruster nozzles, reusable rocket nozzles, thermal protection systems, and turbo pump components for space vehicles. The growing application of silicon carbide fibers reinforced composites is motivating the manufacturers to replace the metal parts in aircraft with the fibers so as to boost the fuel efficiency of aircraft engines and used in the manufacturing of engines, thermal protection systems, and turbopumps. Companies are looking forward to expanding the application base of SiC fibers in the aerospace industry. For instance, in March 2017, it was reported that General Electric had adopted SiC fibers-based CMCs to produce its newgeneration jetliner engines so as to improve fuel efficiency. Furthermore, SiC fibers is also being demanded by the power generation industry. They are used to manufacture land-based gas turbine engines, radiation blankets, furnaces, and components, and other materials in the power and energy generation industry.
