Polynaphthylbiphenyl polyetherketone (PPEK) is a high-performance special engineering plastic with good market development prospects.

Phenylbiphenyl polyetherketone (PPEK) is a new type of special engineering plastic made on the basis of polyetherketone (PEK).

Polyetherketone (PEK) is a high molecular polymer whose main chain is formed by alternating ether bonds and ketone bonds. Polyaryl ether ketone is a typical product, using difluorobenzophenone and hydroquinone as raw materials. Made by polycondensation under high temperature conditions, it has excellent mechanical properties, tensile strength, elastic modulus and high thermal stability. It is an engineering plastic with excellent comprehensive properties. However, the synthesis conditions of polyetherketone are high, the cost is high, and the processing is difficult, so its application is limited.

According to the “In-depth Market Research and Development Prospects Forecast Report of China’s Phenylbiphenyl Polyetherketone (PPEK) Industry from 2022 to 2027” released by the Industrial Research Center Shows that heteronaphthalene biphenyl polyether ketone is an upgraded product of polyether ketone. Using readily available and low-priced phenol and phthalic anhydride as raw materials, diazinone bisphenol monomer (DHPZ) can be synthesized, and then polymerization reaction can be used to obtain heteronaphthalene biphenyl polyetherketone. The reaction conditions of polynaphthyl biphenyl polyether ketone are relatively mild, the production cost is reduced, the processability of the product is improved, and the glass transition temperature is increased. It is a high-performance special engineering plastic that has more advantages than polyether ketone. Promotional, greater potential for future market development.

Affected by the transformation and upgrading of the manufacturing industry, my country’s market demand for high-performance materials continues to rise, so heteronaphthalene biphenyl polyether ketone has attracted attention. In November 2020, the 2,500-ton new heterocyclic high-performance plastics project planned and constructed by Chengdu Tianshun Poly New Materials Co., Ltd. held a groundbreaking ceremony at the Urban Industrial International Innovation Port in Jinjiang District, Chengdu. The first phase plans to build a 500-ton new heterocyclic high-performance plastics project. Plastics, the second phase plans to build 2,000 tons of new heterocyclic high-performance plastics, including polynaphthalene biphenyl polyether ketone (PPEK) production capacity.

In order to further improve the comprehensive performance of heteronaphthalene biphenyl polyether ketone and expand its application scope, research on its modification is still in depth. The modified products that have been developed include nano silicon nitride filled heteronaphthalene biphenyl polyether ketone composites, nano Silica filled heteronaphthalene biphenyl polyether ketone composite materials, carbon fiber reinforced heteronaphthalene biphenyl polyether ketone composite materials, etc. In addition, heteronaphthalene biphenyl polyether ketone can also be used to modify other polymer materials, such as heteronaphthalene biphenyl polyether ketone modified epoxy resin, which can improve the high temperature resistance of the product.

Industry analysts said that heteronaphthalene biphenyl polyether ketone and its modified materials can be widely used in aerospace, nuclear industry, In industries such as electronics and electrical, automobile transportation, precision machinery, and environmental protection. For example, phosphotungstic acid/sulfonated heteronaphthalene biphenyl polyether ketone can be used to prepare proton exchange membranes, which are used in the field of methanol fuel cell manufacturing; quaternized heteronaphthalene biphenyl polyether ketones can be used to prepare anion exchange membranes for use in methanol fuel cells. Efficient and environmentally friendly all-vanadium flow battery manufacturing field. Overall, the heteronaphthalene biphenyl polyether market has good development prospects.
