摘要
A process for the improving the mechanical properties and the sealing properties of elastomer gaskets. The elastomer is prepared by adding to an elastomer composition, at the time of the preparation phase, fibers having an average length on the order of 2 to 12 mm. The elastomer is molded, by injection or by compression transfer, such that the orientation of the fibers in the elastomer is obtained by positioning and orienting of the nozzle or the channel inlets into the mold cavity. The fibers, embedded in the elastomer have an orientation that is, parallel to a surface against which a ridge of the closure device comes into contact and perpendicular to the closure device when the butterfly valve is shut.
