In recent years, China's plastic industry has shown an obvious trend of industrial agglomeration, and the number of large-scale enterprises has grown rapidly. The industrial structure is gradually adjusted to the direction of scale and intensification. The industry of plastic additives is also adjusting to the direction of large-scale and intensive, which is especially obvious in plasticizer, heat stabilizer, impact modifier and processing additives.

At present, we should speed up the pace of technological innovation and actively develop "green, environmental protection, non-toxic, efficient" plastic additives. Professor Gong introduced plasticizers, flame retardants (bromine flame retardants, organophosphorus flame retardants, organosilicon flame retardants, inorganic flame retardants), heat stabilizers (rare earth composite stabilizers, metal soap calcium / zinc composite heat stabilizers, organotin stabilizers, rare earth composite heat stabilizers, hydrotalcite heat stabilizers), impact modifiers and processing aids, foaming agents, lubricants, antioxidants Light stabilizer, nucleating agent, antistatic agent, cross-linking agent, antibacterial agent and biological killing agent, mould inhibitor, dripping agent and antifogging agent, acid remover and other plastic additives are comprehensively described. In terms of functional masterbatch, Professor Gong also introduced the composition, classification, product performance and application of functional masterbatch. Mainly including filling masterbatch, color masterbatch and so on.
