STABILIZATION OF RUBBERS IN AGGRESSIVE ENVIRONMENTS.

Abstract

Elastomeric materials are being used increasingly in aggessive environments. Techno-economic arguments have essentially ruled out the production of a new antioxidant-modified polymer for each potential application, and attention has recently turned to the concept of high concentration bound antioxidant master-batches which can be added to the rubber formulation during normal compounding, but which become interpenetrating networks with the unmodified rubber during the vulcanization procedure.
