Material Notes:
Applications & Industries:General: 25% Glass fibre is the most widely used filler. It improves the creep resistance, compressive strength, rigidity, and wear of PTFE, both at low & high temperatures. It is chemically stable (except to strong alkalis & hydrochloric acid - HF). 25% glass filler improves the wear resistance properties of PTFE.Chemical: Dynamic & shaft seals and Seals & gaskets. Flat gaskets are used to seal flanges in pipelines.Construction: Bridge bearings. Slide bearings.Engineering: Anti - friction bearing cages & bearing plates; Bearings, bushes, shaft bearings / seals (in combustion engines); Chain tension slide bearings. Film bearings. Multi - layer composite bearings; Laboratory equipment. Measuring & control technology; Pipe supports. 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, and some fluorine compounds at elevated temperatures. Resistant to organic solvents. This compound has a fair resistance to the following chemicals: Ammonium hydroxide, Bromine, Cromic acid, Hydroboric acid, Hydrochloric acid, Hydrocyanic acid, Nitric acid (0 - 50%), Phenol, Sodium hyrdroxide. This compound has an unsatisfactory resistance to the following chemicals: Fluorosilicic acid, Hydrofluoric acid, Hydrogen sulphide (solution), Sodium silicate.Information provided by Dalau
