Sinochem New Network News – Recently, Sinopec Baling Petrochemical Company's Synthetic Rubber Division, Epoxy Resin Division, and Technology Center have taken the lead in developing curing agents for fiber-reinforced composite materials and water-soluble impurity removal technology in SEBS adhesive. In addition to these key projects, they also worked on the development of a new medical-grade SIS brand, SIS hydrogenation pilot technology, and research into the synthesis process of dicyclopentadiene-phenol epoxy resin. These five initiatives were evaluated and approved by Sinopec Group.
One of the major breakthroughs is the water-soluble impurity removal technology for SEBS glue, which utilizes emulsion washing and acid neutralization techniques. This innovation significantly reduces the lithium content in SEBS, known as “green rubber,†while improving its color stability. As a result, the product has expanded into the medical field, such as infusion bags, meeting strict medical standards. The technology is now considered among the best in the world.
Another notable project is the development of a new SIS product for traditional Chinese medicine drug delivery. This product offers low application temperature, strong initial adhesion, and moderate peel force, making it ideal for plasters and pastes. It avoids the allergic reactions commonly associated with natural rubber-based products. The pilot test has been successfully completed, and the product has received user approval.
The SIS hydrogenation pilot technology has produced three different grades of pilot products and four invention patents have been filed. These products are used in optical cable grease and lubricants to enhance viscosity. The next step is to move towards mass production in an upcoming industrial plant.
The curing agent for fiber-reinforced composites was developed specifically for wind turbine blades. It is currently being sold at around 300 tons. The product’s high strength, modulus, and toughness make it well-suited for use by wind power blade manufacturers.
Lastly, the dicyclopentadiene-phenol epoxy resin developed through this project shows great potential in high-speed printing inks and laminates, indicating strong market demand and promising future applications.
