Xylan Coated Screws, Fasteners and Fixings
Xylan coating, sometimes known as PTFE coating, Teflon coating, or high performance coating, are common names for a family of fluoropolymer-based coatings – specifically designed to improve the functionality, performance and lifespan of screws, fasteners and fixings.
Xylan coatings are typically composed of various materials such as PTFE, FEP and PFA. These fluoroplastics provide low friction and non-stick properties, as well as higher working temperatures and additional chemical resistance.
PTFE, or Polytetrafluoroethylene, was the first ever synthetic fluoropolymer discovered in 1938 and is the most common material in Xylan coating. It offers a very low coefficient of friction and is resistant to most chemicals and solvents. One of the main benefits is its high working temperature of up to 260°C – the highest of any fluoroplastic. However, it does not melt when heated so is considered difficult to process.
FEP, or Fluorinated Ethylene Propylene, was designed as a melt-processable version of PTFE, sharing many similarities in terms of its physical and chemical properties. FEP hosts a lower working temperature of up to 200°C, but has great working properties at cryogenic temperatures down to -200°C. It also provides good resistance to UV radiation.
PFA, or Perfluoroalkoxy, is melt-processable and has a higher working temperature of 260°C. It hosts similar properties to FEP – offering excellent chemical resistance and strong mechanical properties in both high and low temperature environments. It also provides good stress and crack resistance and a higher melting point compared to PTFE and FEP.
There are many types of Xylan coating that are each designed for specific applications. Please see below a full list of Xylan coatings – all of which we can supply here at Fastenright.
All products are coated to order with relatively short lead times, in both small and bulk quantities.
If you require more information or would like to order screws, fasteners or fixings with a Xylan coating, please contact us.
