Laporte plc

Laporte plc was a British chemicals business founded in 1888 by Bernard Laporte, a German chemist. The company began by supplying peroxide for bleaching straw used in the manufacture of boating hats. From that narrow starting point, it expanded into a broader supplier of bleaching materials and commercial laundry chemicals, eventually becoming a diversified industrial group with activities across specialty chemicals, formulated materials, pigments, additives, peroxides, and products serving electronics and other industrial applications. Laporte’s development reflected the evolution of the British chemical industry from basic process chemistry toward higher-value industrial and specialty products. During the 1980s, the company disposed of its manufacturing operations, indicating a shift away from a more traditional production-oriented model. It subsequently emphasized businesses with specialized formulations, technical applications, and branded or proprietary product lines. The company pursued an acquisition-led strategy in the 1990s. In 1993 it acquired Evode Group plc, a supplier of adhesives and specialty products. In 1994 it bought Aztec Peroxides Inc., a United States peroxides business, strengthening its position in a field connected to its original peroxide heritage. In 1998 it acquired Inspec Group plc, another specialty-chemicals supplier. These transactions broadened Laporte’s geographic reach and product portfolio while increasing its exposure to industrial materials and niche chemical applications. Laporte’s reported operations included Pigments & Additives, Formulated Products & Compounds, Computers & Electronics, and Specialty Chemicals. Pigments and additives activities included iron-oxide pigments for plastics and clay-based additives supplied through Southern Clay Inc. Formulated products and compounds included PVC and thermoplastic elastomer materials used in data-transmission cables, electrical insulation, and beverage-closure seals, with Alpha Gary Inc. identified as an operating business. The specialty-chemicals portfolio included peroxides through Aztec Peroxides Inc. Other named products included Fulacolor and Laponite, produced at the company’s additives operation in Widnes, United Kingdom. Laporte was publicly traded in the United Kingdom and became a constituent of the FTSE 100 Index, reflecting its scale and market significance at the time. Its corporate structure nevertheless changed substantially at the end of the 1990s. In 2000, divisions representing approximately 55 percent of the company’s revenue were sold to Kohlberg Kravis Roberts. Those businesses, including Pigments and Additives, Formulated Products & Compounds, and Computers & Electronics, subsequently became associated with Rockwood Holdings Inc. In December 2000, Degussa SKW, a joint venture between Degussa AG and SKW Trostberg, acquired the remaining business. The performance-chemicals operations were later sold by Degussa to Cognis. The Laporte plc corporate entity therefore ceased operating as an independent chemicals group in 2000. Its industrial legacy continued through successor businesses and product operations. The additives business was acquired by Altana AG in October 2013 and operated within Altana’s BYK Additives & Instruments subdivision. Laporte is consequently best understood as a former British corporate and industrial-chemicals brand whose businesses were redistributed among successor owners rather than maintained as a continuing standalone company.

Laporte plc was established in 1888 by Bernard Laporte, described as a German chemist, to supply peroxide used in bleaching straw for boating hats. The business then broadened into other bleaching applications and commercial laundry chemicals. This early connection with peroxide remained relevant to the company’s later specialty-chemicals portfolio, although Laporte eventually developed activities well beyond its original market. The company’s later history was characterized by diversification and restructuring. During the 1980s, Laporte disposed of its manufacturing operations. The move reduced its exposure to conventional manufacturing and helped direct the business toward specialized materials, formulated products, and technical chemical applications. Laporte became a publicly traded British industrial group, listed on the London Stock Exchange and included in the FTSE 100 Index. During the 1990s, acquisitions were central to the company’s expansion. In 1993, Laporte acquired Evode Group plc, which supplied adhesives and specialty products. The following year it acquired Aztec Peroxides Inc., a United States peroxides business. This transaction expanded Laporte’s international presence and strengthened its activities in a product category related to the company’s historical expertise. In 1998, Laporte acquired Inspec Group plc, adding further specialty-chemicals capabilities. Laporte’s operating structure included four principal areas: Pigments & Additives; Formulated Products & Compounds; Computers & Electronics; and Specialty Chemicals. The pigments and additives activities included iron-oxide pigments for plastics and clay-based additives supplied through Southern Clay Inc. The formulated-products business included PVC and thermoplastic elastomer materials for data-transmission cables, electrical insulation, and beverage-closure seals, with Alpha Gary Inc. identified among the operating businesses. Specialty chemicals included peroxides through Aztec Peroxides Inc. The group also operated an additives business in Widnes, where Fulacolor and Laponite products were produced. The company was broken up at the end of the 1990s and beginning of the 2000s. In 2000, Laporte sold major divisions representing approximately 55 percent of revenue to Kohlberg Kravis Roberts. Those operations subsequently became known as Rockwood Holdings Inc. In December of the same year, Degussa SKW acquired the remainder of the business. The performance-chemicals activities were later sold by Degussa to Cognis. Laporte therefore ended its existence as an independent corporate group in 2000. Some of its businesses and product activities continued under successor owners. In October 2013, Altana AG acquired the additives business, which was operated within BYK Additives & Instruments. The company’s historical significance lies in its transformation from a small peroxide and bleaching supplier into a listed British specialty-chemicals group, followed by the sale and redistribution of its operations among larger industrial and investment owners.
