Global Polymerization Initiator Market was valued at USD 3.5 billion in 2020 and is anticipated to grow at 4.4 billion till 2027 recording a CAGR of 4.5% during the forecast period 2021-2027. Polymerization initiators are a chemical process in which a chemical species reacts with a monomer to form an intermediate compound that will link with a large number of new monomers to form a polymeric compound. In radical polymerization, these initiators are used to control the initiation by light or heat. Polymerization persulfates, the fastest-growing component, are a category of active chemicals with a peroxide group for each sulphur in their subatomic structure. Electrochemical processes produce persulfates, which are also known as Alkali Metal Salts. These persulfates are used as oxidising agents and initiators. Because the practical features of those materials remain the same as previously, and they are used reciprocally in big applications, the physical appearance of the persulfate kinds is determined by oxidation requirements and price. Potassium, ammonium, and sodium are the three types of persulfates. Due to the increase urbanization and industrializations shows rapid growth in the infrastructure. Increasing in packaging industry and increasing awareness regarding the multi-functional of polymers. Also, polymerization initiator materials are included in the various construction. Rising R&D and increased the technological advancement rising the demand of high performance polymer by various manufacturing sectors will the growth of the market. However, High cost of complex polymerization initiator raw materials, lack of trained professional, safety concerns and growing usage of recycled plastic are the major factors that hinder the growth of the market. Global polymerization initiator market is surging owing to frequent acquisitions and launchings by the market players. In July 2019, United Initiators acquired 100% shares of hidrojen peroksit A.S., which is a single plant producing different qualities of hydrogen peroxide in Turkey. This will help the organization to increase its product portfolio and serve several non-polymer applications such as textile, mining, water treatment, and farming. The company will also be investing actively in improving the efficiency of the plant and also increase the capacity of hydrogen peroxide in the future.
