Made from food-grade polypropylene particles through integral extrusion molding, this product features a three-dimensional honeycomb hollow structure with uniform and dense internal honeycomb walls, resulting in extremely lightweight yet highly rigid material. Polypropylene is waterproof and non-absorbent, resistant to acid and alkali corrosion, formaldehyde-free, and fully recyclable. It is resistant to deformation and cracking under high and low temperature conditions, making it widely used as the core material for various lightweight sandwich panels, suitable for vehicle cabins, RVs, ships, and prefabricated lightweight composite panel processing.
