Specialty Polystyrene Resins Market size was valued at USD 118.3 million in 2021, growing at a CAGR of 2.8% during the forecast period 2022-28. Specialty polystyrene resins has a wide range of properties that makes it an ideal candidate for its use in various industries. It exhibits good film stiffness, decent water resistance, fast air dry, well-adjusted to deprived elasticity. Specialty polystyrene is used as for smoothing sealers, as a spray in coatings and primers, furniture and flat-board surfaces, among others. These are the major factors expected to drive the market. Moreover, polystyrene resin provides physical and mechanical forte in the packaging application. It is also considered to be the most versatile type of polymer foam which further raises the demand for polystyrene resins. However, the varying strategies of prominent corporations, fluctuating prices of raw materials diminishes the growth of market. Specialty polystyrene resin provides physical and mechanical robustness in packing applications, and it is the most adaptable type of polymer foam. It is lightweight and has a high strength-to-weight ratio because to its cross-linked structure. It is made up of individual cells of low-density polystyrene. It has applications in food service and protective packaging.
