In 1969, ARCO merged with Sinclair, and the first PBHT production plant was built in Channelview, Texas, under the trademark Poly bd®, mainly for military and aerospace applications. In 1986, ARCO's PBHT business was sold to Horsehead Industries, and Poly bd® became a business of Sartomer, part of Pony Industries Holding. In 1989, Sartomer's Poly bd® business was acquired by Atochem in France.
