Method for extruding a compressible layer on a printing sleeve

摘要

A process for preparing a composition including microspheres comprising adding a rubber polymer, a sulfur-based curing agent, and microspheres to a rubber mill mixer and mixing the added materials in the rubber mix to form a composition, wherein the composition comprises less than about 40% solvent. The process is useful for preparing formulations that can be used with printing blanket compressible layers. The microspheres are not adversely affected by the mixing.
