On August 3, the ** website of Chongqing released the \"14th Five-Year Plan for the High-Quality Development of Chongqing’s Manufacturing Industry (2021–2025)\“. Chongqing will develop industrial clusters in the fields of electronic information worth trillions of yuan, automobiles worth 500 billion yuan, equipment worth 300 billion yuan, materials worth 600 billion yuan, specialty consumer goods worth 500 billion yuan, and biomedicine worth 100 billion yuan. The Plan states that Chongqing will build industrial bases for polyamide and polyurethane materials with international competitiveness. In the field of new chemical materials, eight industrial chains have been developed, including those for polyurethanes, polyamides, polymethyl methacrylate, polyesters, polyolefins, polycarbonates, polyoxymethylenes, and biodegradable plastics. Leveraging the production capabilities of local MDI (diphenylmethane diisocyanate) and AA (adipic acid), efforts will be made to strengthen the planning and development of projects related to epoxides and polyether polyols. Existing enterprises in fields such as PTMEG (poly**furane) and polyurethane resins will be encouraged to expand their production capacity, thereby improving and strengthening the polyurethane industry chain. Leveraging the local production capabilities of AA (adipic acid), efforts are being made to strengthen the development of products such as ADN (adiponitrile)–HDA (adipamide), nylon 66 salts (adipic acid/adipamide salts), and nylon 66 (polyadipic acid). At the same time, efforts are being made to attract and foster enterprises in areas such as long-chain nylons and high-temperature resistant nylons, in order to build a complete polyamide industry chain. Leveraging the advantages of local MMA (methyl methacrylate) projects, efforts will be made to strengthen the planning and development of propylene-based raw material projects, increase MMA production capacity, and actively attract and foster enterprises in the PMMA (polymethyl methacrylate) sector in order to build an MMA industry chain. Leveraging the local PTA (terephthalic acid) resources, efforts will be made to strengthen the planning and development of projects related to raw materials such as EG (ethylene glycol), PG (propylene glycol), and BG (butylene glycol). This will help enterprises increase their PET (polyethylene terephthalate) production capacity, accelerate the development of PET engineering plastic products, and build a complete polyester industry chain. Leveraging its advantages in acetylene and vinyl acetate products and technologies, it develops the polyolefin industry chain, including VAE (vinyl acetate-ethylene copolymer), EVA (ethylene-vinyl acetate copolymer), T-PVA (thermoplastic polyvinyl alcohol) resins, PVB (polyvinyl butyral) resins, and EVOH (ethylene-vinyl alcohol copolymer) resins. Leveraging the dimethyl carbonate project, and in combination with the planned MTO (methanol-to-olefins) project and propylene project, a bisphenol A project is planned to be developed in order to create a polycarbonate industry chain. Leverage methanol resources and POM (polyoxymethylene) technology advantages to expand POM production capacity. Leveraging local acetylene resources, it develops downstream products such as BDO (1,4-butanediol), PBAT (polyhexanedioic acid/butylene terephthalate) and PBS (polybutenedioic acid/butanediol ester), in order to expand the scale of biodegradable plastic products. According to the plan, Chongqing will leverage its advantages in local natural gas (shale gas) resources and methanol production capacity, strengthen the planning and construction of MTO and BDO projects, actively pursue the establishment of demonstration facilities for natural gas applications, and ensure a stable supply of raw materials for synthetic materials. Encourage ammonia/sulfuric acid and urea production enterprises to develop industrial applications, and promote the planning and construction of downstream utilization projects for chlorine and methanol products, striving to achieve local consumption and reduce the amount sent for external transportation. Chongqing will also leverage the feature of chemical products having numerous functional factors to develop fine chemicals. To meet the development needs of industries such as electronics and automotive, efforts are made to attract and foster enterprises in areas such as chemicals for electronics and new types of coatings.
