PPS National Standards Review Conference Held in Shanghai

From October 26th to October 27th, the "Plastic Polyphenylene Sulfide (PPS) Molding and Extruding Material Part 1: Naming System and Basic Standard" National Standards Review Conference was held at Shangyu Hotel, TC15/SC9 members and standards A total of 24 representatives from the working group attended the meeting. The participating committee members and representatives carefully discussed and reviewed the standard review draft and related materials. The committee members voted on the criteria and a total of 24 votes were valid. The passing rate was 100% of the number of voters, and the voting members accounted for 75 of the total number of members. % or more (the total number of members is 29).

This standard plan project is proposed by the China Petroleum and Chemical Industry Federation, and the National Plastics Standardization Technical Committee Engineering Plastics Subcommittee (SAC/TC15/SC9) is responsible for the drafting of the project by China Blue Chenguang Chemical Research & Design Institute Co., Ltd. The Synthetic Resin Quality Supervision and Inspection Center is a participating unit. The project has undergone a lot of preliminary research. In 2012, it held the first, second, and third working meetings in Chengdu, Dunhuang in 2015, and Shangyu in 2017, and finally formed a standard approval. draft.

Polyphenylene sulfide (PPS) is a crystalline polymer, and its production and demand ranks behind five general-purpose engineering plastics such as nylon (PA), polycarbonate (PC) and polyoxymethylene (POM). The sixth largest engineering plastic is called. PPS is a kind of special engineering plastics with excellent overall performance. Due to the affinity of PPS and inorganic fillers, reinforcing fibers, and compatibility with other polymer materials, PPS can be made into different types of reinforced fillers and polymer alloys. It is widely used in automobiles, electronic appliances and household appliances, machinery industry, petroleum, chemicals, pharmaceuticals, light industry and other industries. For example, fiber-grade PPS is a high-performance special engineering plastic with excellent performance. It is widely used in fields such as electronics, automobiles, machinery, environmental protection, and aerospace, and is an important foundation for the development of high-tech industries such as information, aerospace, environmental protection, and energy. Sex materials.

Whether in the international market or the domestic market, the market demand and output of polyphenylene sulfide have increased year by year, and will remain unchanged in the next few years. Polyphenylene sulfide is in a period of rapid development. During this period, foreign countries have taken the lead in establishing corresponding international standards and national standards, and are gradually developing a polyphenylene sulfide standard system. In this period, China did not have technical regulations to restrain bad manufacturers and bad foreign companies, nor did it have uniform standards to guide the market. Administrative law enforcement agencies did not regulate to determine whether products were qualified, let alone set up technologies for foreign products. Barriers and reasonable protection of the interests of China's production enterprises. Therefore, the development of China's polyphenylene sulfide (PPS) standard and the market are seriously mismatched. It is imperative to study and establish a national standard for polyphenylene sulfide (PPS).

The conference has promoted the establishment of a national standard system and has promoted a key step. After the standard is released, it will standardize the production of products and guarantee the quality of product specifications, and further increase the overall competitiveness of China's polyphenylene sulfide producers.
