Environmental protection and high efficiency into plastic additives development direction
Green environmental protection is the theme of today's social development, plastic additives are an indispensable part of the plastic industry, but it has a pollution disadvantage that can not be ignored. China is the world's largest producer and consumer of plastic additives, and the future development direction is mainly focused on product structure adjustment and product upgrading.
Environmental protection and high efficiency into plastic additives development direction
pvc plastic additives is currently the most variety and the largest amount of plastic additives. Because PVC resin relative to other resins more need and easier to use additives to improve or improve performance, at the same time, PVC plastic is cheap, practical, in all categories of plastics most widely used, the largest amount, so the current plastic additives mainly PVC plastic additives, the amount of plastic additives accounted for about 90%. From the demand growth rate of PVC plastic products in China is expected, the overall growth rate of plastic additives will be maintained at 8%-10%.
The cost-effective ACM replaces the low-quality CPE, and MBS achieves import substitution. From the modification effect of plastic products, ACM is the best low temperature toughness, the most cost-effective products; ACR is the impact modifier with the best comprehensive performance, while MBS is the impact modifier that must be added to transparent products. 1 China's ACR products accounted for only 10%, low-end CPE accounted for 60%, and foreign impact modifier product structure of ACR accounted for 60%, the future with the increase in China's demand for high-performance PVC additives, China's consumption ratio will gradually shift to the trend of consumption ratio in developed countries; 2 some Chinese enterprises MBS product technology breakthrough, product quality improvement, open the import substitution market.
Environmental requirements and standards are becoming stricter, and organophosphorus flame retardants are ushered in development opportunities. It is expected that by 2018, the global market capacity of flame retardants will reach 2.62 million tons, with an annual growth rate of about 5%. In recent years, with the advantages of environmental protection and safety, the pace of replacing organic halogen-based flame retardants is getting faster and faster. At present, the main problem of organophosphorus to replace organic bromine flame retardants is that the cost of flame retardants used is higher than that of bromine flame retardants when achieving the same flame retardancy effect.
The development direction of plasticizer is environmental protection: safe, green, special. Plasticizer is plastic processing additives in the production capacity and consumption of the largest variety, its output accounts for about 60% of the total output of plastic additives about 2.9 million tons, at present China's production capacity of more than 4 million tons, a relative surplus. Due to the lack of isononyl alcohol, decyl alcohol and other raw material sources in China, the production and marketing structure of phthalic acid plasticizers in China and Europe and the United States is very different. Compared with foreign countries, China in the food, medical and other fields of plastic additives testing standards lag seriously, liquor "plasticizer" exceeded the event we still remember, in China's foreign standards forced, the future plasticizer will be safe, green and professional direction development, environmental protection products including high carbon alcohol esters, citric acid esters, epoxies, polyesters, biodegradable class.
In plastic additives, both plasticizers and impact modifiers reflect the phenomenon of excess production capacity, but in fact, the main Chinese product structure is unreasonable, low quality product surplus is serious, high-end products including environmentally friendly plasticizers, flame retardants and ACM, MBS and other market demand still does not match. Therefore, whether it is for the industry or enterprises, we believe that the future development trend of auxiliaries is a new, efficient and environmentally friendly plastic auxiliaries to replace traditional high pollution and low quality auxiliaries; Similar to ACM, MBS impact modifier technology breakthrough, product quality improvement, can replace low-quality CPE and imported products; The enterprise has changed from a single production of a type of auxiliary agent to a comprehensive service provider of auxiliary agent, providing comprehensive services for downstream plastic production enterprises.
