Rulon Bearings
Dalau Dalcon 018 85% Virgin PTFE, 15% Graphite
Categories: Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)

Material Notes: Applications & Industries:
General: Graphite filler improves the sliding properties & thermal conductivity of PTFE and has one of the lowest coefficient of frictions. It has low wear in water and is a good bearing material on soft metals & in high speed contact.
Chemical: Dynamic & shaft seals; Construction; Bridge bearings; and Slide bearings. Engineering: Anti - friction bearing cages & bearing plates; Bearings, bushes, shaft bearings / seals (in combustion engines); Film bearings. Multi - layer composite bearings. Fabric bearings; Laboratory equipment. Measuring & control technology: Pipe supports. Expansion bellows. Glandless valves & pumps, valve seats; Piston rings in hydraulic systems; and Piston rod packings used in compressor plunger pumps & valves.

CHEMICAL RESISTANCE: The strength of the carbon - fluorine bond and the shielding of the carbon chains by the fluorine atoms result in a chemical inertness which is virtually universal, except alkali metals, fluorine under certain conditions, some fluorine compounds & halogen gases at elevated temperatures.
