Abstract
A process for the continuous production of cured rubber membrane, the process comprising (i) preparing a continuous stream of curable rubber composition; (ii) forming the continuous stream of curable rubber composition into a continuous green-rubber extrudate; (iii) curing the continuous green-rubber extrudate to form a continuous cured membrane; and (iv) fabricating the continuous cured membrane into rolls of cured membrane, where the curable rubber composition is characterized by at least one of a t90 at 190° C. of from about 1 to about 12 minutes and a T5 at 135° C. of from about 5 to about 20 minutes.
