Unsaturated Polyester Resin Reactor

Unsaturated polyester resin reactor is a special reaction equipment for synthesis and modification of thermosetting resins such as unsaturated polyester resin (UPR), epoxy resin, phenolic resin and acrylic resin. Its basic principle is to complete the whole process of polycondensation, crosslinking dilution, cooling and blending through the cooperative work of precise temperature control, frequency conversion stirring, vacuum dehydration and condensation reflux systems in a closed pressure-bearing kettle, realizing stable synthesis of resin from liquid raw materials to qualified finished products. It has core characteristics of closed anti-volatilization, precise temperature control, uniform stirring, high dehydration efficiency, safety and environmental protection, serving as the core production equipment for resin production, composite materials, artificial stone, coatings and adhesives industriesReference: Baidu Encyclopedia - Unsaturated Polyester Resin. As a source factory integrating R&D, design, manufacturing, installation, commissioning and EPC services, AIX Boiler strictly implements GB150 Pressure Vessels standards of Standardization Administration of China, focusing on R&D and manufacturing of unsaturated resin reactors, providing safe, stable, efficient and customizable integrated resin synthesis solutions for global resin enterprises.
