The first is to do a good job in the basic work of the Chemical Industry Park. The company completed basic work such as control detailed regulations for the Chemical Park Project, land disaster pressure assessment, land surveying and mapping, started the design, geological survey, and land acquisition report of the two main roads, and implemented the BT unit for infrastructure construction of the Chemical Park. The second is to complete the demolition of the park's main roads. Completed the demolition work of more than 1,100 mu of land on 2 main roads and mixing stations. At present, 4.5 km of subgrade has been completed. The third is to improve the park infrastructure facilities. The construction of special railway lines for the park has been approved by the Ministry of Railways; it has been supported by PetroChina and invested more than 50 million yuan in the construction of natural gas pipelines and supply stations to ensure the supply of natural gas in the chemical park. The fourth is to accelerate investment promotion and project promotion. A 600-mu land acquisition index has been implemented for the Southwest Pharmaceutical No. 1 Plant; the production license for chlorine gas production moved from Mianyang to Hechuan has been implemented through the Sichuan Provincial Development and Reform Commission; the investment of 200 million yuan has been invested by the Singapore Kayfa Group to build a water supply and sewage treatment plant in the Chemical Industry Park; and Huaneng Group has been introduced Invested 1.8 billion yuan to build a thermal power plant in the chemical park, and incorporated the cogeneration project into Chongqing's "12th Five-Year Plan" cogeneration plan.

Polyamide 6 (PA6) is also known as Nylon 6 or polycaprolactam. It is one of the most extensively used polyamides globally. It is synthesized by ring-opening polymerization of caprolactam. Melting point of polyamide 6 is 223°C.
While, Polyamide 66 (PA66) or Nylon 66 is one of the most popular engineering thermoplastics and is majorly used as a replacement to metal in various applications. Nylon 66 is synthesized by polycondensation of hexamethylenediamine and adipic acid (two monomers each containing 6 carbon atoms). Melting point of polyamide 66 is 255°C.
