At 10 a.m. on May 6, the first silo of Jiangsu Hongjing’s 50,000-ton/year EnBA plant was successfully lifted. After two days of intensive lifting operations, by May 8 all six silos of the EnBA plant had been installed, marking significant progress in the project construction and simultaneously kicking off the equipment installation work. EBA is an ethylene-butyl acrylate copolymer with good tear strength, decent toughness at low temperatures, and excellent optical properties. The synthesis method is similar to that of EAA, involving the free-radical polymerization of ethylene and butyl acrylate under high temperature and pressure. It is mainly used for modifying polymers such as ABS, AS, and PVC, and is primarily employed in the production of films, adhesive resins, and cables. It is often processed into film by blow molding, or used for stretch winding. EBA itself retains its impact resistance at minus 40 degrees, and the material is flexible, making it suitable as a toughening agent ； At the same time, EBA has a high polarity and good compatibility with various polymers. It can be used for impact resistance and compatibilization modification of PE, PP, PET, PA, PC, ABS, PC/PBT, PC/ABS, etc. It is a universal masterbatch carrier. EBA can be used in various fields such as wires and cables, flexible packaging, films for frozen food packaging, extruded coatings, medical hoses, adhesives, and more. It is widely used, especially in the field of wires and cables, mainly due to its good processability. It has good heat resistance, with a thermal decomposition temperature of 330 degrees, which is higher than EVA’s 240 degrees ； The extrusion processing temperature can reach up to 300 degrees, which is higher than EVA’s 220 degrees ； It also has high melting and softening points, resulting in a wide processing window ； Its processability is similar to that of LDPE, with low viscosity. It has high filling capacity, good compatibility, and high resistance to environmental stresses. With the same proportion of monomeric acid content, EBA has about twice the polarity of EVA; 15% BA is equivalent to 25%–30% VA, offering higher polarity, better compatibility, greater filling capacity, and improved resistance to environmental stresses. For halogen-free flame retardant additives (aluminum hydroxide/magnesium hydroxide), the filler content is higher (up to 70%). EBA has good molding properties. Due to the wide molecular weight distribution of EBA, it has high melt strength, resulting in cables with a smooth surface, as well as high gloss and flatness. The EBA end products have excellent performance. EBA has a high melting point and softening point, resulting in good temperature resistance for the finished cables. The EBA modulus is low, resulting in better impact resistance and flexibility for the finished cable.
