From Humble Beginnings to Global Success

Olin Corporation began in 1892 as a small blasting powder supplier in East Alton, Illinois. Following a few decades of success, along with some fruitful acquisitions, Olin added Mathieson Chemical Corporation into the mix, further increasing Olin’s product offering. Over time, the new Olin has grown and expanded to encompass several complementary business units, among them—Olin Chlor Alkali Products & Vinyls and Olin Epoxy. In 1931, Olin brought Winchester into the fold; the leading manufacturer of ammunition in the United States. Collectively, these business segments employ 8,000 professionals in more than 15 countries with customers in nearly 100 countries across the globe.
