Dalau Dalcon 086 100% Virgin PTFE modified polymer
Categories: Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE)

Material Notes: Applications & Industries:
General: The static and dynamic friction coefficient are numerically equal, consequently no ’Stick Slip’ occurs. Modified PTFE has an advantage over Homopolymer (Normal PTFE), in that it has the following features: Lower deformation under load and permanent deformation. Higher elongation at break. Higher flex life. Higher dielectric strength. Higher transparency. Lower permeability. Better heat sealability.
Chemical: Dynamic & shaft seals; Pipes & tubing for carrying chemicals; and Seals & gaskets. Flat gaskets are used to seal flanges in pipelines.
Construction: Bridge bearings. Slide bearings.
Electrical: Communications, radio & television engineering, cable insulation; Electrical plant construction & electronics industry (connectors & terminals); General electrical equipment (P.T.F.E. excellent electrical insulating material); and Power plant installations (switchgear).
Engineering: Anti - friction bearing cages & bearing plates; Bearings and bushes; Diaphragm pumps. 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.
Food: Dynamic & shaft seals (used in the food processing industry) and Linings & coatings (fertilizer plant & food industry line equipment).

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, and some fluorine compounds at elevated temperatures. Some Fluorinated Hydrocarbons (refrigerants) cause reversible swelling i.e. Tetrafluorodichloroethane Frigen 21, giving a 9.6% weight increase. For specific data on chemical resistance of this material we have a computer database with all the information covering over 90% of all known chemicals.
