Sinochem New Network News: Recently, Sinopec Baling Petrochemical Company's Synthetic Rubber Division, Epoxy Resin Division, and Technology Center have taken on several key projects focused on the development and industrialization of curing agents for fiber-reinforced composite materials, as well as the removal of water-soluble impurities in SEBS adhesive. In addition to these, the team has also been working on five other important projects, including the development of a new medical SIS brand, SIS hydrogenation pilot technology, and research into the synthesis process of dicyclopentadiene-phenol epoxy resin. All of these initiatives have successfully passed technical appraisals organized by Sinopec Group.
One of the notable projects is the development of a water-soluble impurity removal technology for SEBS adhesive. This project employs emulsion washing and acid neutralization techniques, significantly reducing the lithium content in SEBS, which is known as "green rubber." The improvement in color stability has expanded the product’s application fields, making it suitable for medical uses such as IV bags. The technology is now recognized as internationally advanced.
Another breakthrough is the new SIS product development, which marks the first time SIS has been applied in traditional Chinese medicine drug delivery systems. The developed SIS products offer low processing temperatures, strong initial adhesion, and moderate peel force, meeting the requirements for plasters and pastes. This innovation helps avoid allergic reactions caused by natural rubber-based plasters. The project has completed pilot testing, and the product has received user approval.
The SIS hydrogenation pilot technology project has resulted in the development of three pilot-grade products and the filing of four invention patents. These products are primarily used in optical cable grease and medium-to-low-end lubricants to enhance viscosity. The next step is to move toward mass production once the industrial plant is established.
In addition, the curing agent designed for fiber-reinforced composites—specifically for wind turbine blades—has already been sold in quantities of around 300 tons. The product’s high strength, modulus, and toughness fully meet the needs of wind power blade manufacturers.
Lastly, the dicyclopentadiene-phenol epoxy resin developed through the synthesis process research shows great potential in applications such as high-speed printing ink and laminates, indicating promising market prospects.
