Flexible Aramid Honeycomb Cores

As a strong, lightweight, and buoyant alternative to solid panels, these aramid honeycomb cores are used to make interior wall panels and floor boards in marine, structural, and industrial applications. Compared to aluminum honeycomb cores, they're lightweight and more flexible, so you'll often find them lining boats and high-speed cars. However, they’re not as strong as aluminum cores. Aramid cores also resist flames, self-extinguish without melting or dripping, and are thermal and electrical insulators. Aramid is commonly known as Nomex.

Composite Fiber Aramid Honeycomb Panels

Carbon Fiber Face

Fiberglass Face

With an aramid honeycomb core sandwiched between carbon fiber or fiberglass for rigidity, these panels are strong, but lightweight, and won’t conduct heat. Often used as wall panels in structural and insulating applications, they’re a lightweight alternative to solid composite and aluminum honeycomb panels.

Carbon Fiber Face—Carbon-fiber-faced panels are stronger and more rigid than fiberglass-faced panels, so they resist deforming from bending, twisting, or buckling. They will, however, splinter from high-impact blows. These panels are lighter than fiberglass-faced panels. However, they conduct electricity, so don’t use them around electrical components.

Fiberglass Face—Fiberglass-faced panels are often used around electrical components because they are good electrical insulators. They resist cracks from bumps and hits better than carbon-fiber-faced panels, but are not as strong or lightweight.

Corrugated Plastic Sheets

Plastic sheets resist punctures, moisture, and many acids. Use them between pallets or layers of stacked material, or to reinforce the bottom of shipping boxes.

Crush-Resistant Corrugated Cardboard Sheets

These sheets have a layer of hexagonal cells instead of typical corrugation, so they distribute loads better than standard cardboard liners. Use them between pallets or layers of stacked material, or to reinforce the bottom of shipping boxes.

Honeycomb-Padded Recycled Paper Packing Rolls

Cushion fragile items similarly to bubble wrap while creating less waste. With a honeycomb design, these rolls stretch when pulled, so you only need about half as much as bubble wrap. They’re made of 100% recycled material, making them more sustainable than general purpose paper rolls. However, they break down quicker when exposed to moisture and friction. These rolls tear by hand and the honeycomb cells grip onto each other, which means there’s no need for scissors or tape to secure the end.

Nonflammable Mica Panels

Designed to withstand the punishing heat of jet engines, these panels retain their strength for hours even when exposed to hot gas flames. Tested to EN 13501-1 Class A1, they meet the strictest non-combustibility requirements. Use them as a lightweight alternative to carbon fiber, plastic, or aluminum to make fire-rated enclosures, electrical housings, and structural panels. They can be machined with standard cutting and milling tools. All ship with a traceable lot number printed on the packaging.
