PTFE Components
Polytetrafluoroethylene (PTFE) is a high performance polymer material which on its own or filled with various fillers has over the years found an ever increasing number of applications throughout industry.
Fillers can be added to PTFE in varying proportions and combinations in order to increase the materials mechanical strength or resistance to wear or creep. Examples of some of the many materials which can be blended with PTFE are:
Glass fibre, Graphite, Carbon, Bronze, Stainless steel, Ceramic, Mineral fibres, Molybdenum, PEEK
PTFE offers important benefits to mechanical and civil engineers, the material properties can be adjusted by incorporating fillers and additives to better suit particular applications.
Increased wear and Creep resistance, mechanical strength and even anti static properties can be incorporated into the final blend, this combined with chemical inertness (excepting high temp alkali metals), and a temperature range of -250 deg C to + 250 C allow the material to be used in conditions prohibitive to other materials.
Diva has progressively developed isostatic moulding as the preferred compression method allowing the production of complex shapes such as:
- Butterfly Valve seats
- Beakers
- Large diameter Thin Walled Tubes
- Floats
- Top Hat Mouldings
- Repair and protection sleeves for glass lined vessels
- PTFE bellows and expansion joints
- Stem Packing Sets
- Bearings and Seals
- Valve Seats
- Turbine heads
We combine moulding techniques and fabrication of PTFE stock shapes to produce complex assemblies, examples of which are:
- Large diameter injector inserts for chemical service
- Solid PTFE dip pipes
- Tower distributor tray assemblies
- Sampling valves for HCl
