Radial displacements and BIO oils
Blade seals installed on turbines must keep the lubricant inside the hub and prevent water contamination.
Travel radials related to wear of the bronze rings (sagging of the blade) forced the seals to a great clearance.
The new environmental standards require more and more the filling of the units by aggressive organic oils to elastomers.
Techoseal DEFENDER Gaskets have specially been developed for this application.

Why polyurethane?
Polyurethane brings several interesting characteristics with respect to the environment in which a blade seal operates.
No stick slip effect (grip) thanks to its better coefficient of friction.
Superior abrasion resistance which increases the longevity of the joint.
Superior mechanical resistance (tensile, tearing, rupture on elongation)
Heat-weldable, it can be mounted without dismantling the blade, delivered in open length. We can weld it on site.
