Electrical brushes and brush materials are used in conjunction with slip rings, commutators or other contact surfaces to maintain an electrical connection in rotary and linear sliding contact applications

Brush seals are used as a barrier against flying debris and liquid.

Flap wheels and specialty abrasives includes cartridge rolls, cross pads, sleeves, unitized or convolute wheels, interleaved flaps, flap discs and other specialized abrasive products converted from coated or nonwoven abrasives.

EDM electrode materials and components consist of highly conductivity and/or arc erosion resistant materials such as graphite, copper or copper graphite.

Slip rings are metal rings that provide a continuous electrical connection through brushes on stationary contacts.

Specialty cement, concrete and mortar contain specialized binders such as K silicate, calcium aluminate, sulfur, and oxysulfate or polymer resins.

Cement, concrete and mortar are polymer or cement-based binders, compounds or aggregate mixtures for joining components and forming structures.
