Polynaphthalene biphenyl polyethersulfone (PPES) has great development potential in the field of membrane material manufacturing and demand is expected to continue to rise.

Polynaphthalene biphenyl polyethersulfone (PPES) is a new type of special engineering plastic made on the basis of polyethersulfone (PES).

Polyethersulfone (PES), a type of polyarylene ether, is a thermoplastic polymer material with excellent comprehensive properties. It has excellent physical and mechanical properties, heat resistance, chemical corrosion resistance, hydrolysis resistance, insulation, etc. Features: As a high-performance engineering plastic, it can be used in a wide range of downstream applications. However, polyethersulfone is insoluble in common organic solvents, which limits its application in paints, coatings, separation membranes and other fields. Therefore, its performance is close to that of polyethersulfone, but there is an urgent need to develop materials with better solubility.

Diphenyl biphenyl polyethersulfone is a polymer prepared from diazinone bisphenol monomer (DHPZ), which can be made from phenol and phthalic anhydride. , these two materials are easy to obtain and low in price, which can reduce the production cost of heteronaphthalene biphenyl polyethersulfone. Compared with polyethersulfone, the physical and chemical properties of heteronaphthalene biphenyl polyethersulfone are similar, and the solubility is significantly improved and the production cost is reduced. Therefore, heterobiphenyl polyethersulfone can be used as a substitute for polyethersulfone and has greater market potential.

According to the “In-depth Market Research and Development Prospects Forecast Report of China’s Polynaphthalene Polyethersulfone (PPES) Industry from 2022 to 2027” released by the Industrial Research Center It shows that heteronaphthalene biphenyl polyethersulfone is one of the engineering plastics with the best comprehensive properties that has been developed so far. It has obvious advantages of high heat resistance and solubility, and can be widely used in aerospace, nuclear industry, Automobile transportation, mechanical equipment, electronic and electrical, environmental engineering and other fields. Among them, membrane materials such as ultrafiltration membrane and nanofiltration membrane are important product types of heteronaphthalene biphenyl polyethersulfone.

Naphthyl biphenyl polyethersulfone has excellent physical and chemical properties, the glass transition temperature exceeds 300°C, and has good solubility and film-forming properties. It is a membrane material with excellent performance. Using heteronaphthyl biphenyl polyethersulfone as the base material and N-methylpyrrolidone (NMP) as the solvent, asymmetric ultrafiltration membranes can be prepared using the phase inversion method and applied in the field of sewage treatment; the hybrid membrane obtained by sulfonation modification is used. Naphthyl biphenyl polyethersulfone has improved hydrophilicity and dielectric properties and can be used to prepare high-flux nanofiltration membranes for use in the field of seawater desalination.

Industry analysts said that from 2016 to 2021, the average annual compound growth rate of my country’s ultrafiltration membrane market size was 12.3%; from 2016 to In 2021, the average annual compound growth rate of my country’s nanofiltration membrane market size will be 16.8%. my country’s ultrafiltration membrane and nanofiltration membrane markets are growing rapidly. As a new material for the production of ultrafiltration membranes and nanofiltration membranes, the demand for heteronaphthalene biphenyl polyethersulfone is expected to continue to rise.

At present, the number of heteronaphthalene biphenyl polyethersulfone manufacturers in my country is small. In order to meet the needs of the downstream market, the industry’s production capacity is gradually expanding. In November 2020, Chengdu Tianshun Poly New Materials Co., Ltd. started construction of a 2,500-ton new heterocyclic high-performance plastics project at the Urban Industrial International Innovation Port in Jinjiang District, Chengdu, with a total investment of 1.037 billion yuan, including heterocyclic biphenyl polyethersulfone. (PPES) production capacity, the first-phase project is 500 tons, expected to be put into production in August 2022, and the second-phase project is 2,000 tons.
