The production of styrenic polymers is done by the polymerization of styrene monomers and chemical compounds such as butadiene, acrylonitrile, and others. Owing to the increasing applications such as in packaging, automotive industry, building and construction, and appliances, the production of styrene-based derivatives is a growing trend. The traditional metallic devices are now being replaced by polymers that can be processed easily, hence the medical plastics market is expanding significantly. The polymers that contain styrene as the main component are known as styrenic polymers. Styrene is produced from ethylene and benzene. The most common styrenic polymer is polystyrene. The physical and chemical properties of styrenic copolymers depend on other monomers in the styrenic polymer chain. The global styrenic polymers market is segmented on the basis of types, applications, and regions. On the basis of type, the global styrenic polymers market is categorized into acrylonitrile butadiene styrene, styrene ethylene butylene styrene, polystyrene, styrene acrylonitrile , and styrene butadiene styrene, etc. Based on the applications, the global market is classified into medical, building and construction, electrical and electronics, automotive industry, consumer goods, marine accessories, and packaging. The regional diversification of the styrenic polymers market is into Europe, Latin America, North America, Asia-Pacific, and the Middle East and Africa. In the medical industry, styrenic polymers are used in the medical devices such as tubes, connectors, IV spikes, equipment housing, bags, liquid delivery systems, and medical packaging. Polystyrene, SAN, ABS, and styrenic block polymers such as SEBS and SBS are the common styrenic polymers that are used for manufacturing medical devices and packaging, thus contributing to the global market growth. Polystyrene is the widely used styrenic polymer in the medical applications while ABS co-polymer dominates the styrenic market. The processing of styrenic materials can be flexible as well as rigid as per the requirement of the end-user. Styrenic polymers provide advantages in design and development of medical parts and devices owing to their flexibility, hence widely used in the market. Additional properties such as unique bonding polarity, chemical inertness, and aesthetic and physical properties are driving the styrenic polymers market in medical applications. The fact that styrenic polymers are costly as compared to other medical polymers such as polyethylene and polyvinyl chloride may hamper the market growth. North America dominated the market for styrenic polymers for the medical applications. Asia Pacific and Europe followed North America in terms of the usage of styrenic polymers in medical applications. In the coming years, the market will be ruled by Asia Pacific owing to the rapid developments in the medical field and the growing population. The growth in the infrastructure industry will make the Asia-Pacific region to become the largest consumer of the styrenic polymers market.
