Introduction
PP honeycomb sandwich panel is a high-performance composite material featuring a classic "sandwich" structure (face sheet + PP honeycomb core). Its core is crafted from food-grade eco-friendly polypropylene (PP), bonded via copolymerization molding technology or special adhesives to ensure exceptional flatness and reliable overall performance. Integrating lightweight yet robust characteristics, corrosion resistance, efficient thermal insulation, and effective soundproofing, this panel is widely applied in RV bodies, refrigerated cargo compartments, logistics vehicles, cold storage facilities, modular housing, climbing walls, and wear-resistant electronic whiteboards. It stands as an ideal choice for scenarios requiring a balance between lightweight construction and long-term durable use. |  |


Packaging & Shipping
To address product damage from violent shaking and collisions during long-distance transportation, we offer two protective solutions:
- Standard protection: Securing products with iron frames, wooden pallets and other accessories to guarantee basic transportation safety.
- Customized protection: Delivering tailored packaging based on your specific requirements, with 30% enhanced performance compared to the standard solution (e.g., specialized shock-absorbing materials, custom-fitted frames).
Lightweight Solutions
Our PP honeycomb sandwich panel provides super performance guarantee:
- Reduced maintenance frequency: Excellent impact resistance, weather resistance and corrosion resistance reduce maintenance and replacement frequency, significantly extending service life.
- Environmental adaptability: Designed specifically for humid, rainy and corrosive environments, such as sewage treatment plant covers.
- Structural stability: Large panel design reduces joints, maintaining beautiful appearance and high structural stability.
