The ideal lightweighting panel material
MetaCORE-LD is MetaCORE engineered into a sandwich panel. This composite structure offers substantial weight reduction with a maximum bonding surface area. As a result, delamination of panels from the core material is a problem of the past.
Just like MetaCORE, MetaCORE-LD offers exceptional support to loads in the normal direction. Unlike other products, MetaCORE-LD goes further by providing unprecedented in-plane loading support. This means MetaCORE-LD panels can be manufactured with greater weight-bearing capacity and lower failures rates.
The thermal conductivity of MetaCORE-LD is also exceptionally low due to the amount of hollow internal space. Values of 25 mW/m-K are typical, and lower values are feasible for bespoke applications.
Between the low density, suppressed failure modes, and thermal insulating properties, MetaCORE-LD is an ideal paneling product.

The MetaCORE product line was conceived as a lightweight impact-absorbing structural material. The same geometric motifs seen with MetaCORE have made their way into MetaCORE-LD, which offers our customers a greater access to bespoke solutions.
Increased resilience: MetaCORE-LD vs. HDPE
Lightweight sandwich panels are great for boxing out structures and providing insulation from the elements. Their fabrication is easy enough: one material (often a foam or honeycomb) is sandwiched between two thin panels fabricated from thermoplastics or metals.
It’s important when using sandwich panels to understand their strengths and weaknesses, particularly since they’re composite structures
with failure modes unique to their construction. Whether it be yielding, face wrinkling of the panel, or shear of the core, exactly what happens when excessively loaded depends on the relative densities and dimensions. These possibilities are well-summarized with a failure mode map. Knowing what failure mode to expect is important since face wrinkling may be acceptable whereas core shear could be catastrophic.
MetaCORE-LD is engineered to shift the boundaries of a standard failure mode map by offering greater operational range of functionality and resilience to failure. Tolerable aesthetic defects can be substituted for catastrophic failure of the core material.
Transportation of goods and products is essential for our quality of life. Lighter, stronger materials let carriers haul more cargo per load, lower operating costs, and increase trailer lifetime. Exceptional cellular volume fraction provides superior thermal insulation for temperature sensitive cargo.
