Coated Sleeving minimizes aeroengine fire risk.

Press Release Summary:



Used on glass braided shielding for aeroengine applications, PTFE-based Turcon® Coating provides resistance to shearing and extreme heat. Aircraft fuel lines and steel clips can be sleeved in Turcon®-treated glass braiding to minimize surface friction. Product is also suited for protecting cables installed in areas at risk of shearing, including cabling next to helicopter rotor blades. Sleeving ranges in size from 0.02-0.6 in. and comes in various colors.

Busak+Shamban Announces Unique Coating Technology of Glass Braided Busak+shielding



Reduces Aeroengine Fire Risk
Improves friction Characteristics and Increases Resistance to Shearing

Fort Wayne, (March 1, 2006) - Busak+Shamban, a worldwide leading supplier of high-quality products and solutions for industrial sealing and bearing systems, announces its unique coating technology that is used on glass braided shielding for aeroengine applications. Turcon®, a PTFE based coating improves friction characteristics and increases resistance to shearing. This innovative method of sleeving has been successfully used around steel clips on fuel line pipes helping reduce aeroengine fire risk.

The copper fuel lines, which wrap around the aircraft engine in a helix, are held in place with steel clips. The fuel lines are subject to possible wear caused by aircraft vibration, which produces friction between the fuel lines and steel clips. The vibrations increase greatly on take off and landing, leading to a possible fire risk if the fuel lines are damaged through friction wear.

With Busak+Shamban's aim of reducing surface friction, engineers proposed sleeving aeroengine fuel pipe clips in glass braided shielding treated with Turcon®. Initially, they added PTFE to the glass braiding material at the manufacturing stage but performance tests showed that friction characteristics were not good enough for the application. Following this, Busak+Shamban engineers developed a unique method of coating the glass braiding with their proprietary Turcon® material in a high temperature sintering process.

This Turcon® coated glass braided shielding has also proved of special value in protecting cables installed in areas where they are at risk of shearing, including cabling next to helicopter rotor blades etc. The Turcon® coated glass braided shielding has proved highly effective in reducing friction and preventing contact wear. It is resistant to the extremes of heat generated by the engine and in some applications, has been found to reduce the effect of fungal growth invasion, which deteriorates copper.

A range of sleeving is now being manufactured by Busak+Shamban, utilizing the liquid Turcon® method of coating, to suit aerospace and other installations where sheer resistance and minimal friction is important. The sleeving is available in diameters from 0.02" to 0.6" (0.5 to 15mm) and is manufactured in different colors for color-coding wiring looms.
