High-Thermal-Conductivity Microencapsulated Expandable Graphite for Enhancing Flame Retardancy and Mechanical Properties of Natural Rubber
May 21, 2025Natural rubber (NR) exhibits superior performance and wide applications, but its inherent flammability limits its use. Due to its low thermal conductivity, NR products accumulate heat under dynamic conditions, accelerating aging and increasing fire risks. To address this, flame retardants like expandable graphite (EG) are incorporated. However, EG faces challenges such as poor hydrophilicity and weak interfacial adhesion with polymers, leading to uneven dispersion and aggregation.
