The main business of the company is the R & D, production and sales of flame retardants, modified plastic particles and products. After years of innovation and accumulation, it has possessed core technologies including halogen-free flame retardant chemical synthesis and compounding application technology, flame retardant modified plastic preparation technology, functional polymer material technology and so on. It is one of the manufacturers of high-performance plastics and resins with differentiated competitive advantages in China.

The halogen-free flame retardants of the company comply with international RoHS, reach and WEEE standards, and have superior flame retardant and environmental protection performance. They are mainly used in the field of new materials such as flame retardant plastics and flame retardant coatings. Modified plastic particles and products are widely used in holiday lighting, electronic appliances, wires and cables, automobiles, liquid crystal displays, medical and health care and other fields. And has established strategic cooperative relations with many well-known enterprises at home and abroad. Through continuous R & D investment and scientific and technological innovation, the company has formed an integrated development model of “basic raw materials – plastic additives – plastic materials” industrial chain, and will march towards high-performance green new materials in the future.

Question 1. Basic information of the company?

Main contents of investor relations activities: the company is a high-tech enterprise introduction industry of high-performance plastics and resins with core original technology and patents. Its main business is the R & D, production and sales of flame retardants, modified plastic particles and products. The products are widely used in festival lighting, electronic appliances, wires and cables, automobiles, medical and health care and building materials

And has established strategic cooperative relations with many well-known enterprises at home and abroad. In addition, in 2021, the company increased the leasing business of building materials and EPP recycling packaging boxes, leasing scaffolding, PP Alloy building formwork, EPP recycling packaging boxes and other products from customers. Building materials can improve the use efficiency and turnover rate of building consumables through the mode of renting and selling on behalf of customers; The repeated recycling and degraded recycling of EPP recycling packaging box can achieve the purpose of plastic reduction, emission reduction and green development. For more information, pay attention to the company’s regular reports and interim disclosure announcements. Question 2: the company’s R & D direction and R & D investment?

A: the R & D expenses of the company from January to September in 2019, 2020 and 2021 were 453942 million yuan, 596919 million yuan and 731109 million yuan respectively, accounting for 3.08%, 3.10% and 3.92% of the sales revenue of the same year; The company continues to increase R & D investment, and the R & D direction is divided into two parts: (1) application scenario and process technology development research of existing products: the company goes deep into the modified plastic market and carries out product performance research from the customer application end, such as antibacterial and mildew prevention of automobile interior and exterior decoration, heat resistance of PS, low warpage and low linear expansion coefficient of flame retardant PC, modification research of recycled plastics, etc; And expand the company’s product categories, such as adding phosphate flame retardant, hydroxide flame retardant, PC rear cover sector, flame retardant PP composite sector instead of PC / ABS sector, EPP foam sector, pet foam sector and other products, so as to broaden the new application market. (2) research reserves of high value added products: the company has set up a Polystone Research Institute and a subsidiary company, Guangdong Polystone Technology Research Co., Ltd., through the combination of independent innovation and industry university research cooperation, to carry out the technical research and commissioned research work of new material products. At present, the research projects of the Department include the pilot study of graphene industrialization and downstream application, the development of PVA composite gel and medical dressing. The research and development of polyimide monomer preparation and composite film technology will provide a long-term reserve for the company. Question 3: the company’s overseas business? A: the company’s main export products include halogen-free flame retardant, modified plastic particles for festival lighting, PS diffusion sector, breathable film and other products. Flame retardants, modified plastic particles for festival lighting and high-end film products are mainly supplied to European and American markets; PS diffusion sector products are supplied overseas according to the delivery needs of Samsung and LG. PE breathable membrane products can be used in diapers, sanitary napkins, protective clothing, etc. at present, the products are mainly exported to non-agricultural countries

Export sales in Europe. Question 4: how competitive is it in the industry? A: the company’s industry is a subdivided industry of modified plastics in the new material industry, and the homogenization competition is relatively fierce. The company actively participates in international competition and integrates into the international high-end supply chain system through rich R & D experience and patented and non patented technology system. The company mainly carries out the layout of core industries according to the downstream demand. For example, the company’s modified plastic particles for Christmas lighting have occupied more than 95% of the market of Christmas lighting in Europe and America; Diffuser products are excellent global partners of Samsung Electronics and LG products in Korea; Halogen free flame retardants for fire retardant coatings are leading in the industry in terms of product performance and cost performance; The strategic goal of the company is to realize the leading of subdivided industries and the import substitution of subdivided products.

Question 5: what is the Jiangling project under construction? How’s it going? A: the company’s Jiangling project refers to the construction of a green new material recycling industrial park in Jiangling County. The first phase mainly constructs EPP (foamed polypropylene) beads, intelligent incubators, EPP auto parts and other products. Based on the company’s own production experience and technology accumulation of modified plastics for many years, EPP beads are prepared from independently modified PP (polypropylene) raw materials through foaming process, and then the EPP beads are dried and formed through mold and assembled into EPP incubator. EPP incubator can replace the traditional polystyrene foamed plastics in the existing market. It has excellent heat resistance, chemical resistance, oil resistance and heat insulation. It is foldable, reusable and recyclable. The company’s products can be used in fruit and vegetable transportation, fresh and cold chain transportation and other fields. Jiangling Circular Industrial Park has recently acquired 181 mu of land through bidding, auction and listing, and has completed the project filing. The project will be completed in three years. Question 6: what are the company’s future development plans and prospects? A: the company will steadily develop the industrial chain integration mode of “basic raw materials – plastic additives – plastic materials”, realize the industry of flame retardant and modified plastic particles, and continuously expand the industrial chain to its upstream raw materials and downstream applications. At the same time, actively incubate small-scale and pilot projects under research, such as high-end membrane materials and polyimide dianhydride monomers, so that they can be put into operation and make profits. Increase the types of high value-added plastic products and high-end new material products of the company, and enhance the comprehensive competitiveness of the company.
