Shim Stock

Cut into custom shapes to create shims that suit your needs. With thickness tolerances as fine as a strand of hair, the shims will precisely align, space, and level components on dies, presses, and machinery.

You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.

Ultra-Chemical-Resistant PTFE—The most chemical-resistant shim stock we offer, it stands up to the widest range of harsh acids, bases, solvents, and corrosive cleaners, even at temperatures up to 500° F. It also won't mar delicate surfaces.

Plastic—Softer than metal, it won't mar delicate surfaces and it will never rust.

Peel-Away Multilayer Shim Stock

Image of ProductInUse. Front orientation. Shim Stock. Peel Away, Sold Individually, Multilayer.

Fine-tune thickness without worrying about stacking multiple shims. Cut the shim stock into custom shapes that suit your needs. It's made of layers of material bonded with adhesive—peel off the layers with a utility knife until you reach your desired thickness. To make peeling easier, warm the created shims to soften the adhesive. With thickness tolerances as fine as a strand of hair, the shims will precisely align, space, and level components on dies, presses, and machinery.

Polyimide—Originally designed for military aircraft, it’s used in everything from aerospace to electronics where weight, electrical insulation, and precision are vital.

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

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.

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.
