The company was founded by
Henry Dunker and
Johan Kock as "Trelleborgs Gummifabriks AB" (the Rubber Factory Corporation of Trelleborg). The company had 150 employees and produced
bicycle tires and rubber for industrial applications. During
World War I, the
Swedish Armed Forces placed substantial orders. By the mid-1930s, the number of employees had reached 1,000. Beginning in the 1950s, Trelleborgs Gummifabriks AB was floated at the
Stockholm Stock Exchange. Its current name was adopted in 1977. Between 1983 and 1991, the company's scope broadened to the areas of mining and metals. In 1999, the scope was narrowed due to specialisation into industrial applications. In 2003, Trelleborg AB acquired the German manufacturer Busak+Shamban and startet manufacturing polymer-based precision
seals under the Trelleborg name. In 2009, the
European Commission fined several marine hose producers, including Trelleborg AB, "...for participating in a
cartel for marine hoses between 1986 and 2007 in violation of the ban on
cartels and restrictive business practices in the EC Treaty (Article 81) and the EEA Agreement (Article 53)." In mid-2012, Trelleborg and Freudenberg formed a 50–50 joint venture in anti-vibration applications for light and heavy vehicles, called TrelleborgVibracoustic. Trelleborg ended this and divested its shares in this venture to Freudenberg in 2016. In 1990, Trelleborg acquired a 50% stake in
Falconbridge Nickel Mines (the Canadian company
Noranda Mines acquiring the other half), giving it a significant footprint in nickel production, which had not previously been major part of its or Boliden's portfolio at that point. In 2022, Trelleborg acquired the
Lindau-based aerospace interiors company, MG Silikon GmbH, an entity within
Saint-Gobain Group, and the US-based company Minnesota Rubber & Plastics from the private equity firm
KKR for US$950million. In 2025, Trelleborg AB announced that they would be acquiring Aero-Plastics Inc. == Operations ==
