The U.S. Synthetic Rubber Program turned a wartime scarcity into a global rubber standard by accelerating synthetic routes before price controls could end.
US PMF/CRP-backed plants pioneered butadiene- and styrene-based polymers that later underpinned everyday tires, gloves, and countless covert industrial uses.
Following the program, private firms secretly diverged into dope-dyed polymers, creating color-stable rubbers long before consumer fashion demanded it.
The program shuffled global rubber markets so dramatically that by 1945, synthetic rubber supply chains rivaled natural rubber in strategic importance.
