The new battery regulations will be implemented in 2026: The Ministry of Industry and Information Technology's mandatory new national standard "Safety Requirements for Power Batteries for Electric Vehicles" will officially come into effect on July 1, 2026, requiring battery systems to be "non flammable and non explosive". EPP, with its extremely low thermal conductivity (0.030-0.035 W/(m · K)), high flame retardancy (UL94 V-0 level), and excellent energy absorption efficiency, has become the core solution for bottom buffering, insulation, and cell spacing in power batteries. It can effectively block heat spread and cope with bottom impact testing.

Automotive lightweighting and compliance: The 2026 Extended Producer Responsibility (EPR) system for automobiles requires a vehicle recyclability rate of no less than 95%. EPP, as a 100% recyclable thermoplastic material, is widely used in bumper buffers, door energy absorbing blocks, and interior parts to help car companies reduce carbon emissions and meet environmental compliance requirements. For example, NIO ET5 and other models have adopted EPP in their battery pack cushioning components, achieving a 30% weight reduction while improving collision safety.

Capacity and technological breakthroughs: The domestic EPP industry continues to expand, and by 2025, Shanghai Petrochemical's market share of foamed polypropylene materials will exceed 50%, with key indicators surpassing imported products. Wuxi Huitong, Zhejiang Huajiang and other enterprises have made significant progress in supercritical CO2 kettle foaming technology and packaging of new energy vehicle battery cells, greatly improving production capacity and customized service capabilities. ‌‌
