Plastic additives will develop towards environmental protection and efficiency

PVC plastic additives are the most widely used and most used plastic additives. Because PVC resin is more and more easy to improve or improve performance with other additives, PVC plastic is cheap and practical. It is the most widely used and used in all types of plastics. Therefore, the main plastic additives are PVC. Plastic additives are mainly used, accounting for about 90% of plastic additives. From the demand growth rate of PVC plastic products in China, the overall growth rate of plastic additives will be maintained at 8%-10%.

Cost-effective ACM replaces low-quality CPE, and MBS achieves import substitution. From the perspective of the modification effect on plastic products, ACM is the best low temperature toughness and the most cost-effective product; ACR is the best comprehensive performance of impact modifier, and MBS is the impact modification that must be added to transparent products. Agent. Domestic ACR products account for only 10%, low-end CPE accounts for 60%, while foreign impact modifier products account for 60% of ACR. In the future, as China's demand for high-performance PVC additives increases, China's A consumption ratio will gradually shift to the trend of consumption ratio in developed countries; some domestic enterprises have achieved breakthroughs in MBS product technology, product quality has improved, and the import substitution market has been opened.

Environmental protection standards have become stricter, and organic phosphorus-based flame retardants have ushered in development opportunities. It is estimated 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, organic phosphorus-based flame retardants have become faster and faster in place of organic halogen-based flame retardants due to their environmental safety advantages. At present, the main problem of replacing organic bromine flame retardants with organic phosphorus is that the flame retardant products used in the same flame retardant effect have higher cost than bromine flame retardants.

The development direction of plasticizers is environmental protection: safe, green and special. Plasticizer is the largest variety of plastic processing aids in terms of capacity and consumption. Its output accounts for about 60% of the total output of plastic additives, which is about 2.9 million tons. At present, the domestic production capacity is over 4 million tons, which is relatively surplus. Due to the lack of raw materials such as isodecyl alcohol and sterol in China, the production and sales structure of phthalic acid plasticizers in China and Europe and the United States differ greatly. Compared with foreign countries, the domestic testing standards for plastic additives in the fields of food and medical care are seriously lagging behind. The "plasticizers" of liquors are still in the memory of the standard, and the plasticizers will be safe in the future. In the direction of green and professional, environmentally friendly products include high-carbon alcohol esters, citrate esters, epoxy resins, polyesters, and biodegradable products.

Among plastic additives, both plasticizers and impact modifiers have shown overcapacity, but in fact, the main reason is that the domestic product structure is unreasonable, and the low-quality products are excessively high. The high-end products include environmentally friendly plasticizers. Flame retardants and ACM, MBS, etc. still do not match market demand. Therefore, for the industry or enterprises, we believe that the future development trend of additives is a new, high-efficiency, environmentally friendly plastic additives to replace traditional high-pollution, low-quality additives; 2 similar to ACM, MBS impact modifier technology A breakthrough, product quality improvement, can replace low-quality CPE and imported products; 3 companies from a single production of a certain type of additives to the auxiliary service providers, providing comprehensive services for downstream plastics manufacturers.
