In the coming years, the demand for China's plastics additive market is expected to grow at an average annual rate of 7%. By 2007, the market's share will reach 3.5 billion US dollars. Among them, the market demand for most plastic additives will increase at an average annual rate of 8% to 10%, while the growth rate of demand for plasticizers that account for the largest share of the plastic additives market will have a noticeable drop, which will affect the entire plastics industry in China. The growth rate of the additive market demand. The main driving force for rapid growth in the demand for plastic additives in the Chinese market has come from China’s rapidly developing construction industry, which has boosted resin production at a rate of 10% per year. Most of these additives are mainly used in polyvinyl chloride, but the growth in demand for polyamides, polycarbonates, polyolefins, polystyrene, and thermosetting resins has also contributed to the growth of additives. At present, 87% of China's locally produced plastic additives are used in the local market, and the remaining plastic additives are used for export. However, with the entry of more multinational corporations and the introduction of more advanced production technologies and products, China's exports of plastic additives will increase. Although Akzo Nobel, Albemarle, Atofina, Ciba Specialty Chemicals, and Romjas have established joint ventures with local Chinese companies, the overall plastic additives market in China is still relatively Dispersed, most companies are small-scale production enterprises that produce low value-added additives.
