Rohm and Haas was a Fortune 500 American chemical company founded in 1909, specializing in specialty materials. Its innovative products served a wide range of industries, including construction, electronics, packaging, and transportation. Key product lines included acrylics (like Plexiglas), emulsions, and various performance chemicals. In April 2009, Rohm and Haas was acquired by The Dow Chemical Company for approximately $15.3 billion. Since the acquisition, Rohm and Haas's operations, technologies, and product lines have been integrated into Dow's various business units, particularly strengthening Dow's performance products and advanced materials portfolios. The Rohm and Haas name, while not an independent operating entity, lives on through its legacy of innovation within Dow.
Served as the global administrative, research, and strategic hub for Rohm and Haas prior to its acquisition by Dow. It housed executive leadership, corporate functions, and central R&D facilities. Post-acquisition, it continues to be a significant office and research location for Dow.
The building, designed by Pietro Belluschi and Rohm and Haas's own engineering department, is known for its distinctive bronze-anodized aluminum sunscreens and its prominent location overlooking Independence Hall. It's considered a notable example of modernist architecture.
Historically, Rohm and Haas was known for a strong research-driven culture, fostering innovation and employee development. It emphasized scientific excellence and a collaborative approach to problem-solving. This legacy influences the culture at the Dow Philadelphia site.
The Philadelphia headquarters was central to Rohm and Haas's global operations and a symbol of its chemical industry leadership for decades. Its location in a major U.S. city facilitated business and talent acquisition.
Prior to its acquisition, Rohm and Haas had a significant global presence with manufacturing plants, research facilities, and sales offices across North America, Europe, Asia-Pacific, and Latin America. These operations were integrated into Dow's existing extensive global network. Dow now supports functions such as research & development, manufacturing, sales, marketing, and customer support for legacy Rohm and Haas product lines (now part of Dow's portfolio) across all major geographic regions, leveraging its global scale and infrastructure.
