Overview
Trelleborg is a Swedish multinational industrial group founded in 1905, headquartered in Trelleborg, Sweden. The company focuses on polymer engineering solutions, providing seals, vibration damping systems, protective coatings, and other products for industries such as aerospace, automotive, infrastructure, and healthcare. Trelleborg has a broad global network and is listed on the Stockholm Stock Exchange.
History
Trelleborg AB traces its origins to the creation of Trelleborgs Gummifabriks AB by Henry Dunker and Johan Kock in Trelleborg, Sweden. The original company operated as a rubber factory and initially manufactured bicycle tires as well as rubber goods for industrial customers. Military demand during the First World War, including substantial orders from the Swedish Armed Forces, contributed to the expansion of production. By the middle of the 1930s, the workforce had reached approximately 1,000 employees, reflecting the company's transition from a local factory into a sizable industrial manufacturer. The company entered a new phase after the Second World War. It became publicly traded in the 1960s, and in 1977 adopted the Trelleborg AB name. During the 1980s and early 1990s, management broadened the group into mining and metals. A notable move in 1990 was the acquisition of a 50 percent interest in Falconbridge Nickel Mines, with the other half acquired by Noranda Mines. These activities gave Trelleborg exposure to nickel production and resources businesses that were not central to its earlier rubber operations. The group subsequently reversed that diversification. In 1999, Trelleborg narrowed its scope and concentrated more strongly on industrial applications. This specialization created the basis for later development as a polymer-engineering group. In 2003, Trelleborg acquired the German manufacturer Busak+Shamban and its polymer-based precision-sealing activities. The transaction brought together several rubber and sealing businesses, including Busak+Shamban, Dowty Automotive, Shamban and Forsheda. The acquired operations became the foundation of Trelleborg Sealing Solutions. Although the Busak+Shamban name continued in some marketing contexts for a period, it was retired from operating locations in 2007 as the activities were brought under the Trelleborg Sealing Solutions identity. Trelleborg continued to expand its engineered-products platform through partnerships. In 2012, it and Freudenberg created TrelleborgVibracoustic, a 50–50 joint venture serving the anti-vibration needs of light and heavy vehicles. The venture combined the partners' capabilities in automotive vibration control. Trelleborg exited the arrangement in 2016 by selling its interest to Freudenberg, illustrating the group's willingness to reshape its portfolio and focus capital on selected industrial polymer businesses. The company faced a significant regulatory and legal setback in 2009, when the European Commission fined several marine hose producers, including Trelleborg, for participation in a cartel covering the period from 1986 to 2007. The case concerned conduct that European authorities regarded as violating prohibitions on cartels and restrictive business practices. It remains an important compliance event in the company's corporate history. In the 2020s, Trelleborg continued to pursue targeted acquisitions. In 2022, it acquired Minnesota Rubber & Plastics from private-equity firm KKR and MG Silikon, a Lindau-based aerospace-interiors company within Saint-Gobain. These transactions broadened the group's capabilities in engineered polymer components and aerospace applications. In 2025, Trelleborg announced a planned acquisition of Aero-Plastics Inc. The group's current structure centers on Trelleborg Industrial Solutions, Trelleborg Sealing Solutions and Trelleborg Medical Solutions. Together, these businesses address industrial fluid handling, precision sealing, anti-vibration systems, aerospace applications, medical devices and biopharmaceutical production. Trelleborg is therefore best understood as a specialized multinational engineering group whose products are frequently integrated into customers' larger systems rather than sold directly to consumers.

Products and positioning
A specialist global engineering partner using polymer technology to solve demanding sealing, fluid-handling, vibration-control and medical-technology challenges.
Industrial polymer systems
Trelleborg Industrial Solutions
This business area supplies hose systems, industrial anti-vibration products and selected industrial sealing systems. Its products are designed for industrial equipment and infrastructure where controlled fluid transfer, resistance to wear or chemicals, and isolation of vibration are important. The offering is primarily business-to-business and is commonly integrated into machinery, process systems and industrial installations.
Precision sealing · 2003
Trelleborg Sealing Solutions
Trelleborg Sealing Solutions develops precision polymer seals and related components for industrial equipment, aviation, vehicles and other technically demanding applications. The business originated in part from the Busak+Shamban acquisition and incorporates capabilities associated with several earlier sealing operations. Its role is to help customers control pressure, fluids, gases and movement in engineered systems.
Medical and biopharmaceutical components
