Halloysite nanotubes as an additive to ensure enhanced characteristics of cold-curing epoxy resins under fire conditions

At present, the most commonly used electrical insulating materials, including cold-curing epoxy resins, are well designed for normal operating conditions. However, new generations of materials should also be capable of withstanding extreme emergency conditions, e.g., in case of fire. For this...
