Virgin PTFE possesses outstanding electrical properties, high dielectric strength, low dielectric constant and very high electrical resistance. The addition of fillers can extensively change these properties. However, fillers generally are only used where the mechanical properties of Virgin PTFE are inadequate as the addition of a filler will generally enhance certain properties of PTFE but reduce others.
Victrex PEEK possesses excellent insulating properties which are retained at over 200 degrees C. Good electrical properties and good thermal stability make PEEK an excellent choice for electrical components operating in aggressive environments.
PTFE and PEEK in electrical applications:
- Low and stable dielectric constants
- High volumetric resistivity, dielectric strength and excellent arc resistance
- High temperature resistance
PTFE slide bearings are used to solve the problems of movement caused by temperature change and differential material thermal expansion, settlement and natural forces encountered by high winds and even seismic activity.Typical applications include:
- Pipe lines
- Heat exchangers
- Pressure vessels
- Storage tanks
- Industrial machinery
- Buildings and bridges
PTFE skidway plates are used to aid the skidding of topsides, jackets and other heavy fabrications. Structures weighing up to 30000 tonnes have been successfully loaded out on PTFE skidways.
We offer a range of PTFE skidway plates to suit customers individual requirements. A typical PTFE skidway plates consists of 2.5mm thick reinforced PTFE hot cure factory bonded under controlled conditions to a 3mm thick carbon steel plate. PTFE skidway plates are normally manufactured with a 25mm welding lip. This prevents the PTFE from being damaged when the skidway plates are tack welded into position. The PTFE / steel bond line and all upper exposed carbon steel surfaces are generally supplied painted with a coat of primer to protect against corrosion.
We are able to offer reinforced PTFE with dimples spread uniformly across the skidding surface. The purpose of the dimples is to retain additional lubricant.
AFT Fluorotec Coatings Limited is part of the AFT Fluorotec group of companies. Recent investment in PTFE and Fluoropolymer coating equipment allows us to supply the full range of Fluoropolymer materials, providing solutions to a broad spectrum of industries. Other than PTFE our range includes PFA and FEP, as well as ETFE, ECTFE, PVDF and PEEK.
Many of these coatings are better known by their trade names: Tefzel® (DuPont), Xylan® & Xylar® (Whitford Worldwide), Greblon® & Senotherm® (Weilburger), Halar® (Solvay), Kynar® (Arkema), Emralon® (Acheson).
