Conductive UHMW Polyethylene Sheets

The addition of carbon allows these sheets to divert static electricity faster than antistatic UHMW sheets. They have a slippery, self-lubricating surface that resists wear. They're often use to make conveyor equipment and parts for sensitive electronic equipment.

High-Temperature Acid-Resistant Silicon-Carbide Ceramic Foam

A silicon carbide coating over a carbon foam base combines the hardness, chemical resistance, and high temperatures silicon carbide is known for with the lightweight versaitility of foam. It’s often used for cores in composite layers and to filter molten metal and corrosive liquids.

The silicon carbide coating acts as a thermal conductor, transferring heat to quickly cool liquids that pass through. Known for its hardness, silicon carbide won’t break down from repeated abrasion. However, because it’s so hard, this material is more brittle than plain carbon foam and less impact resistant than balsa wood, PET, and PVC foam cores.

Acids and bases can’t penetrate the silicon carbide coating, even at high temperatures. Instead, contaminants stick to the surface, making it a great filter for corrosive liquids and environmental pollutants such as exhaust. If using this material as a filter, choose a foam with more pores per inch for a slower flow rate, and a foam with fewer pores per inch for a faster flow rate.

If you cut this material, the underlying carbon foam is exposed. Carbon foam does not have the temperature range and chemical resistance of its silicon carbide coating, so it will break down more quickly at exposed points.

Odor-Removing Pleated Panel Air Filters

Carbon granules absorb odors. Pleats create a large surface area to filter without reducing airflow. The cardboard frame won't warp because it is treated to resist humidity.

Strong Odor Removing—Packed with 15 times more carbon than standard odor-removal air filters to eliminate heavy odors.
