LIQUID RUBBER ARTICLE IN SITU COMPOUNDING INTO A FORMING MOLD

摘要

A method for making cured polymeric articles such as gaskets or seals in sit u (within a forming mold) from a feed stream compounded polymer admixture of (a) a first batch admixture of base polymer and a first curing component of a plural component curing combination, (b) a second batch admixture of the base polymer and a second curing component, and (c) a third batch admixture of a carrier and a plurality of performance additives. The third batch admixture is provided from a vessel having a relatively small volume (when compared to the volume of the vessels holding the first and second batch admixtures); this small volume enables precise formulations of additives and rapid changeover of additive formulations for the base polymer.
