About AmSty

Americas Styrenics LLC (AmSty) is a leading integrated styrene and polystyrene producer. We offer solutions and services to customers in multiple markets throughout the Americas. The chemicals and resins we produce are essential for making products that impact our everyday lives, such as appliances, food packaging, home furnishings, medical products, insulation, tires, shoes, and even solutions for water treatment. Sustainability is at the core of everything we do, from product design and raw material procurement to manufacturing and logistics. Our ongoing innovations make it possible to reduce the amount of material in products, accelerate plastic recycling, and reduce energy consumption and air emissions. At AmSty, we are driving sustainable change.

AmSty was initially formed in 2008 as a joint venture between The Dow Chemical Company (Dow) and Chevron Phillips Chemical Company LP (CPChem). In 2010, Dow sold its AmSty ownership and other styrenics assets to Bain Capital as a standalone company, which came to be known as Trinseo LLC (Trinseo). Today, AmSty is a 50/50 joint venture between Trinseo and CPChem.

AmSty is headquartered in The Woodlands, Texas, with operations in multiple sites across the Americas and over 500 employees and contractors. We manufacture styrene monomer at our St. James, Louisiana, plant and polystyrene at six polystyrene resin plants in:

• Allyn’s Point, Connecticut
• Cartagena, Colombia
• Hanging Rock, Ohio
• Joliet, Illinois
• Marietta, Ohio
• Torrance, California

We are also a 50% owner in a joint venture company, Regenyx, that transforms recycled polystyrene plastic into styrenic liquid in Tigard, Oregon.
