New Breakthrough in PVC Chemical Additives Industry

The recent technological evolution of PVC chemical additives in the plastics industry marks a new dimension in the rheological control ability of polymer materials. The new additives regulate the rheological properties of the melt through the design of molecular topological structure. The ultra-high molecular weight characteristics of PVC regulators for PVC foaming process trigger the transition of interfacial activation energy levels, and its long chain structure forms a three-dimensional network blocking effect in the plasticization stage, effectively inhibiting the elastic collapse of the melt.

The breakthrough in surface energy modification technology has led to the formation of a densified gradient structure in the epidermis of the product, and the directional suppression of crystal defect density and the regulation of free volume distribution have achieved the coordinated optimization of transmittance and haze. The improvement of weather resistance index is due to the blocking efficiency of the stable groups in the molecules of PVC chemical additives on the photooxidation chain reaction, and its free radical capture mechanism shows self-healing characteristics under ultraviolet radiation. This innovation in technical path is reshaping the performance boundary between rigid PVC and soft products, and promoting the extension of application scenarios to extreme working conditions.

This technological breakthrough is mainly reflected in the research and development of new PVC chemical additives. The R&D team has successfully developed a series of high-performance PVC regulator products through the optimization design of molecular structure and the improvement of production process. These new products are particularly outstanding in improving the melt strength of PVC and can significantly improve the pore structure of PVC foam products. Experimental data show that after using the new regulator, the pores of PVC foam sheets are smaller and more uniform, the toughness and strength of the products are greatly improved, and the surface quality is also better.

Industry experts pointed out that with the increasingly stringent environmental protection requirements and the intensification of market competition, PVC processing companies have put forward higher requirements for the performance and environmental protection of additives. The emergence of new PVC chemical additives has not only achieved a breakthrough in performance, but also conforms to the industry development trend in terms of environmental protection. Its promotion and application will help promote the PVC processing industry to develop in the direction of green, high efficiency and high quality.
