Highly Wear-Resistant PTFE Sheets

Filled with carbon and graphite, these naturally slippery PTFE sheets stand up to wear better than standard PTFE. Often fabricated into wear rings, wear pads, and rotational bearings, they resist expanding and maintain their strength when exposed to heat.

Porous Conductive Carbon


Low Flow	Medium Flow	High Flow

Often used in filtering, this brittle, glass-like carbon has pores that allow fluid and air to flow through. Its low surface resistivity also makes it a good electrical conductor. This material is also temperature and chemical resistant.

Odor-Removing Air Filter Media

Carbon granules inside this media absorb odors from the air. Choose media with a high carbon concentration to tackle strong odors. Cut it to the size you need and attach it to a frame.

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.
