In CATL’s latest energy storage container, Kingfa Technology’s FRPC-980 series flame-retardant PC/ABS alloy is undergoing severe tests – under the burning of a needle flame at 1100°C, the embedded silica aerogel particles form a dense insulation layer, allowing the material to maintain structural integrity at a high temperature of 800°C for more than 2 hours. This breakthrough stems from the innovative molecular sieve flame retardant system: the phosphorus-nitrogen flame retardant is embedded in the mesoporous silica skeleton, so that the 0.4mm thickness can achieve UL94 V-0 flame retardancy, and the peak heat release rate is reduced by 72%. Even more sophisticated is the design of the conductive carbon black early warning network. The material resistivity is reduced to 10³Ω·cm, which can monitor the abnormal current of battery thermal runaway in real time. According to the Ministry of Industry and Information Technology, my country’s new energy storage installed capacity will reach 100GW in 2027, giving rise to an annual demand for flame-retardant PC alloys exceeding 300,000 tons. The low-temperature resistant grade developed by Polytron Technologies has an impact strength retention rate of more than 80% at -40°C and has been used in energy storage power stations in high-cold areas; Water shares provide protection solutions for BYD blade battery packs through an insulation formula with a CTI value of 600V. In the energy storage base in the Gobi Desert of Qinghai, these safety lines built with polymer materials are protecting clean energy assets worth hundreds of billions of yuan, and also witnessing the transformation of China’s engineering plastics from a follower to a rule maker.
