(RAC), a subsidiary of Tongcheng New Materials Group, was incorporated in June 2011 and is located in Shanghai Chemical Industry Park, a national chemical park, covering an area of 120,000 square meters, with a registered capital of 176 million RMB, and was put into operation in December 2012. It is a rubber auxiliary production base integrating modern research, experiment and application.

Now we have 15,000 tons per year of p-tert-butylphenol production plant; 10,000 tons per year of phenolic resin production plant; 15,000 tons per year of olefin production plant. In addition, the second phase of 60,000 tons of resin project, catalyst project will be completed and put into operation soon. In recent years, the company's operation has developed well and is in a stable development stage, and in 2019 the company achieved business revenue of 723 million yuan, operating profit of 277.89 million yuan, and paid 55.85 million yuan in tax.

Exhibits

1. p-tert-butylphenol aldehyde resin is a non-reactive thermoplastic resin. The preparation process uses a relatively mild catalyst with good compatibility with the reaction system, and controls the aldehyde-phenol ratio under vacuum conditions to improve the viscosity enhancement effect of the product. It can be added into the rubber to improve the processing performance, prevent the rubber surface from oxidation and hardening, and ensure the adhesion and softness of the rubber. It has good compatibility with various rubbers and can be widely used in various synthetic and natural rubbers. It is especially suitable for tires and rubber products that need to be laminated in the process.

2. p-Octylphenol formaldehyde resin is a rubber tackifying additive, which is an indispensable tackifier for rubber products processed by multi-layer film lamination or pressing, as well as rubber-based tire products molding process. The alkylation process of this project uses reusable high temperature resistant sulfonic acid loaded cationic catalyst as the alkylation catalyst, with high catalytic efficiency and adjustable intermediate alkyl phenol composition; the lipidation process controls the ratio of aldehydes to phenols under vacuum conditions, which significantly improves the tackifying effect of the product in rubber products. The p-octylphenol formaldehyde resin can not only enhance the adhesion of synthetic rubber and improve its processability, but also can be used in large quantities in the formulation of synthetic rubber to improve the mechanical properties of tires.

3. p-tert-butylphenol is a chemical intermediate and stabilizer for the production of general household products (such as detergents, soaps, soaps), oil-soluble phenolic resins, surfactants, adhesives, UV absorbers, rubber vulcanizing agents, inks, flame retardants and other products. The project adopts a two-stage tandem continuous reaction process, with stable reaction and high conversion rate, and the product purity can reach more than 99.99% after distillation and purification. Because of its high purity, low impurity content and low melt color, the product of this project is also particularly suitable for the preparation of optical polycarbonate materials, and has a strong competitive edge in the same industry at home and abroad.
