Raw Materials

Rubber

Compresses and bounces back to shape; often used for sealing, cushioning, and shock absorbing

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing

Ceramic

Hard and wear resistant, it also withstands corrosion and high temperatures

Mica

An electrical insulator that resists high temperatures; use in circuit breakers and heating elements

Carbon

An electrical conductor that’s often used in electronics and sensors

Felt

Thicker and more absorbent than fabric for insulating, polishing, cushioning, and gasketing

Sealing

Gasket Material

Gasket Material

Cut custom shapes and sizes to fill gaps between flat surfaces

EMI/RFI Shielding Gaskets

EMI/RFI Shielding Gaskets

Fit around enclosure doors or data connectors to prevent inaccurate signals and flickering displays

Rope Seals

Insulate the edges of oven, furnace, and boiler doors to keep heat in

Edge Seals

Block dust, water, and wind from entering the gaps around doors and windows

Heating, Ventilation, and Air Conditioning

Pipe Insulation

Pipe Insulation

Fit around pipe, tubing, and tanks to reduce heat loss or condensation
