DuPont was one of the first companies that I'm aware of to explore encapsulation. It's kind of ironic, DuPont has always extolled the virtues of HWE cleaning, and then when they decided to enter the commercial carpet cleaning business they concluded that encapsulation was the answer. I actually discovered that DuPont was performing encapsulation at about the same time that I was learning about encapsulation for my own cleaning business. Recognizing that DuPont had resorted to encapsulation certainly helped me to appreciate that I was traveling on the right path pursuing encapsulation technology.
DuPont made a strong attempt to enter the commercial carpet cleaning market nationwide. They set up a company called DuPont Commercial Flooring. They used highly aggressive tactics to muscle into major metropolitan markets. And they succeeded to penetrate many of the major markets throughout the country. DuPont's history with encapsulation was disrupted however. When they sold off their carpet fiber production to Koch Industries they also parted with their carpet cleaning enterprise. The new moniker for the Resistech empire thus became "Invista" with new owners of the company at the helm. I'm not sure there's quite as much interest in their maintenance services as there had been before, when it was run under the DuPont brand.

In addition to DuPont/Invista, Interface Carpets also implemented their own encapsulation program called ReSource. And Collins & Aikman is promoting their in-house encapsulation program under their Syon-5 label.
