Oakdale, Minnesota - 3M subsidiary Dyneon has launched a new fluoroelastomer product which it claims offers resistance to biodiesel at higher service temperatures.
Dyneon said the FPO 3741 was the first product in its new range of peroxide curable fluoroelastomers that had been designed for the extrusion of fuel line hoses.
The company said its tests had shown FPO 3741 had resistance to rapeseed oil methyl ester (RME), the most commonly-used biodiesel in Europe, at 150Âº C.
A second new grade of fluoroelastomer developed by Dyneon, E-19789, was a peroxide-curable low fluorine terpolymer designed for miscellaneous sealing applications in automotive fuel containment systems.
The company said even after 1000 hours at 150Âº C, both products showed a constant low swell level and retention of physical properties.
