Method for the addition of vulcanized waste rubber to virgin rubber products
Patent
·
OSTI ID:434162
The invention is a method of using enzymes from thiophyllic microbes for selectively breaking the sulfur rubber cross-link bonds in vulcanized rubber. The process is halted at the sulfoxide or sulfone step so that a devulcanized layer is reactive with virgin rubber. 8 figs.
