[1] As of 2016, Bain sold all of its stock in Trinseo, grossing $1.69 billion for 37,269,567 shares, resulting in Trinseo's “full independence as a public company.”[2][3] The company offers a broad line of plastics and latex binders, which are used primarily in the automotive, appliances, electronics, packaging, paper & board, textiles and carpet industries, among others.

Trinseo materials are used widely in cars and trucks, home appliances, consumer goods, electronics, electrical & lighting, building & construction, medical supplies, and packaging.

[6][7][8] Trinseo's precursor Styron was formed in August 2009 when Dow Chemical Company combined several of its businesses--styrenics; polycarbonate and compounds & blends; Dow Automotive plastics; emulsion polymers (paper and carpet latex); and synthetic rubber — as part of a larger process of identifying and selling non-strategic assets.

[9][10] Several private equity firms bid on Styron, including TPG Capital, Apollo Management, and Lotte Group.

[11][12] On March 2, 2010, Bain Capital announced that it would purchase the newly formed company for $1.63 billion,[13] with Dow retaining a 7.5% stake.

[17] In March 2023, over 8,000 gallons of "latex finishing material" leaked into Otter Creek, a tributary of the Delaware River, from a Trinseo plant in Bucks County, Pennsylvania.
