English: This sheet of synthetic rubber coming off the rolling mill at the plant is now ready for drying, B.F. Goodrich Co., Akron, Ohio. Synthetic rubber made by the "ameripol" process is derived from butadiene (a petroleum derivative). In this rolling mill the crumbs of rubber are squeezed dry of excess water and pressed together into the blanket shown here
In 1940, B.F. Goodrich Company scientist Waldo Semon developed a cheaper version of synthetic rubber known as Ameripol. It made synthetic rubber production much more cost effective. |
