ACP Skin Polypropylene Honeycomb Panels
Polypropylene Honeycomb + Aluminum Composite Panels
Polypropylene honeycomb panels faced with ACP panels (Aluminum Composite Panels) provide higher structural strength compared to aluminum sheet facing. It solves the challenge of insufficient strength of aluminum facing honeycomb panels through the complementary material properties and structural synergy innovation.
- High specific strength and stiffness.
- Shear and impact resistance.
- High energy absorption capacity.
- Fire and weather resistance.

Aluminum Composite Panels
Aluminum composite panels are constructed by laminating aluminum layers with a PE (Polyethylene) core material using a polymer adhesive. They perfectly blend the texture of metal with the lightweight properties of plastic. This composite structure, comprised of vastly different materials, retains the core strengths of the original materials while cleverly addressing their respective performance shortcomings, resulting in a series of exceptionally comprehensive properties.
- Decorative: It offers a luxurious feel and rich, vibrant decorative effects.
- Durability: It is resistant to weather, corrosion, and impact.
- Safety: It offers outstanding fire and moisture resistance, as well as effective sound insulation, heat insulation, and earthquake resistance.

Lightweight Polypropylene Honeycomb Core
Polypropylene honeycomb is a lightweight, rigid thermoplastic used as the core of sandwich panel structures. Like aluminum honeycomb, it is also recyclable. Different honeycomb cell sizes have different densities and provide different mechanical strengths. Our honeycomb core is made of high modulus thermoplastic polypropylene plastic, which is flexible and not easily deformed.
