Introduction
The global new energy industry, covering electric vehicles, container energy storage, and renewable energy equipment, is facing an upgraded demand for lightweight, safety, and sustainable materials. Traditional metal, wood and solid plastic materials can no longer balance weight reduction, structural strength and fire safety requirements.
PP circular honeycomb core, as an advanced thermoplastic sandwich core material, has become a mainstream alternative material for global new energy manufacturers. With a unique regular circular honeycomb structure, it realizes high specific strength, stable physical properties and full recyclability, perfectly matching the long-term development trend of the new energy industry.
Core Performance Advantages for New Energy Scenarios
Ultra-Lightweight & High Specific Strength
PP circular honeycomb core features a low density of 60–100kg/m³, reducing the overall structural weight by 50%-70% compared with metal materials. Its strength-to-weight ratio is 3-5 times higher than solid PP sheets. Lightweight design effectively reduces vehicle energy consumption, improves EV driving range, and lowers transportation and installation costs for energy storage equipment.
Class V0 Flame Retardant & High Safety
Custom UL94 V-0 flame retardant grade is available for new energy scenarios. The modified PP formula effectively blocks flame spread, meets international automotive and energy storage fire protection standards, and greatly improves the safety of battery packs and energy storage cabinets.
Excellent Thermal & Electrical Insulation
The honeycomb cavity structure forms a stable air insulation layer with low thermal conductivity, which stabilizes the internal temperature of battery modules and avoids extreme temperature loss. Meanwhile, the pure PP material provides reliable electrical insulation, effectively protecting high-voltage new energy components.
Impact Resistance & Energy Absorption
The uniform circular honeycomb structure can evenly disperse external impact and vibration energy. It serves as an excellent buffer and protective structure for battery modules, effectively resisting structural damage caused by vehicle bumps and equipment vibration.
Corrosion Resistant & Long Service Life
Different from metal materials that are prone to rust and wood materials that are easy to mildew, PP honeycomb core is moisture-proof, chemical-resistant and aging-resistant. It can work stably in harsh environments of -30℃ to +80℃, adapting to complex working conditions of new energy vehicles and outdoor energy storage equipment.
100% Recyclable & Eco-Friendly
As a full thermoplastic material, PP honeycomb core has no harmful additives and can be completely recycled and reused. It conforms to EU RoHS, CE and global circular economy standards, helping new energy enterprises achieve green production and low-carbon certification.
