Qingdao Freyr Graphite Co., Ltd., a leading manufacturer in the graphite industry, has launched its high-purity natural graphite for friction materials, delivering remarkable benefits to the global automotive and industrial sectors.
Natural 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.
