It is learned from the press conference of Tianjin Economic and Technological Development Zone held on June 3 that during the "14th Five-Year Plan" period, Tianjin Nangang Industrial Zone will focus on its functional positioning as a world-class chemical new material industrial base, and accelerate regional development and construction and attract investment. And project implementation.

At the end of the "14th Five-Year Plan", the output value of the chemical production project in Nangang Industrial Park reached 130 billion yuan, and the tax revenue exceeded 8 billion yuan. Three characteristic industrial parks will be built, namely, a clean energy industrial park with an output value of 10 billion yuan and an output value of over 5 billion yuan. Yuan’s electronic chemical industrial park and the medical and health new material industrial park with an output value of more than 2 billion yuan are striving towards the goal of “China’s top 30 chemical parks”.

The industrial structure of the Nangang Industrial Zone is expected to be significantly optimized. The output value of strategic emerging industries dominated by new chemical materials will account for no less than 40%, and the new increase will account for no less than 50%; the output value of two or three new companies will exceed 10 billion. Yuan’s leading enterprises have formed a number of key enterprises with an output value of over 1 billion yuan and "specialized, refined, special and new" enterprises with an output value of over 100 million yuan.

During the "14th Five-Year Plan" period, Nangang Industrial Zone will take Sinopec's 1.2 million tons/year ethylene industrial cluster project and the "Two Chemicals" relocation project as development opportunities to improve the industrial chain and create comprehensive utilization of olefins, new chemical materials, high-end precision and special purpose Three main industrial chains of chemicals, and ten sub-industrial chains of high-performance synthetic resins and composite materials, coatings and adhesives, new energy materials, electronic information materials, biodegradable materials, and biomedical materials.

(1) Industrial chain of comprehensive utilization of olefins

C2: Use the ethylene produced by the MTO device and the ethylene device to develop products such as ethylene oxide, ethylene glycol, polyvinyl chloride, vinyl acetate, lithium battery electrolyte solvent, polycarbonate, α-olefin, and high-performance polyethylene , And extend downstream to produce coatings, adhesives, surfactants, plasticizers, synthetic lubricants, polycarboxylic acid water reducers, polyether polyols, polyolefin lithium battery separators, high-performance polyolefins, etc. C3: Use the propylene produced by the MTO device and the ethylene device to develop raw materials and products such as propylene oxide, epoxy resin, acrylic acid and esters, acrylonitrile, and high-performance polypropylene. C4: separation of butene-1, isobutylene, butadiene and other raw materials, focusing on the development of methyl ethyl ketone, PMMA, TPU, ABS/ASA resin, SBS and other products.

(2) Industrial chain of new chemical materials

High-performance synthetic resins and composite materials industry chain: will focus on the development of high-performance polyolefins, engineering plastics, modified plastics and alloys, special fibers, composite materials, etc., such as polyolefin elastomers, metallocene polyolefins, ultra-high molecular weight polyolefins Vinyl resin pipes, rods and fibers, polycarbonate, polyether polyol, modified engineering plastics, etc., are coupled with advantageous fields such as electronics and electrical appliances, automobiles, aerospace, equipment manufacturing, construction, and medical and health care in the Economic Development Zone. At the same time, we will develop advanced emerging materials such as liquid crystal polymers, polysulfone, polyimide, carbon nanotubes, and graphene.

Electronic information materials: develop high-temperature-resistant halogen-free epoxy resins, insulating films, photosensitive dry films, polyimide flexible copper clad laminates, etc. in printed circuit boards; develop silicon carbide and gallium nitride in semiconductor substrates and supporting materials , Chemical mechanical polishing slurry, polishing pad, etc.; in the production of integrated circuits, the development of wet electronic chemicals, electronic high-purity gases and special gases, special epoxy resins, photoresists, etc.; in the field of materials for display devices Develop materials for display devices such as polyimide alignment agents, mixed liquid crystal materials, ultra-high barrier films, and conductive silver pastes. Biomedical materials: The development is mainly used in the repair or replacement of built-in artificial bones and joints, hearts, heart valves, esophagus and other tissues and organs, and external artificial heart-lung machines, artificial limbs, artificial teeth and other natural polymer materials; mainly used Synthetic polymer materials used in bone cement, prosthetic joints, sutures, catheters and other diversion tubes, drug slow and controlled release carriers, dental filling materials, etc.; mainly used to repair or replace human soft tissues, hard tissues and organs or A composite material that enhances its function and the manufacture of artificial organs. Biodegradable materials: develop PLA and PBAT biodegradable plastics in advance, while focusing on the development trends of other types of biodegradable plastics such as PBS and PCL, and make good project reserves.

(3) High-end fine and special chemicals

Electronic chemicals: focus on the development of photoresist and packaging materials used in semiconductor materials, as well as adhesives and electrolytes used in liquid crystal materials. High-end fine chemicals: Utilize raw materials such as ethylene oxide, propylene oxide, and Sinopec's bisphenol A to develop chemical raw materials such as ethylene glycol, propylene glycol, polyether, methyl ethyl ketone, and produce unsaturated resins and epoxy resins. And other resin products, and then produce high-performance coatings and adhesives and other products. Develop products such as dimethyl carbonate and lithium battery electrolyte, and at the same time extend to products such as cathode materials, anode materials, separators, packaging materials, etc., to build a lithium battery industry development cluster and form a linkage with the automobile industry in the economic development zone. Relying on raw materials such as ethylene oxide and propylene oxide, prioritize the development of epoxy resin, unsaturated resin, nitrile rubber and other products to provide raw material support for the development of the wind power industry in Tianjin.
