Trelleborg develops, manufactures and markets polymer-based sealing solutions for water, drainage and sewerage pipeline systems. Trelleborg is a global engineering group whose leading positions are based on advanced polymer technology and in-depth applications know-how. They develop high-performance solutions that seal, damp and protect in demanding industrial environments.
The Group has annual sales of approximately SEK 27 billion (EUR 2.5 billion), with around 20,000 employees in over 40 countries. The head office is located in Trelleborg, Sweden.
The Forsheda brand was established in 1946 and has since then been a mark for leading edge competence in polymer and pipe sealing technology.
Forsheda has been the pioneer of many new sealing systems such as integrated seals for concrete and plastic pipes where the seal is integrated into the pipe socket during manufacture.
In October 2003 Forsheda was acquired by the Trelleborg Group.
Polykemi delivers four different materials for the different pipe seals, diameter 50-710mm;
Power Lock, Sewer Lock, Anger Lock, Wonder Lock and DIN Lock.
The seals has unique design in which the rubber/TPE sealing element and the reinforcing plastic (Polykemi material, yellow/blue) are bonded together to make a one-piece seal.
Trelleborg Pipe Seals
The demands are very high on accurate measurement, correct stiffness, flexibility and approval to be used for drinking water.
Material: Depending on the demand the materials used to carry the rubber/TPE seal is a POLYfill with glasfibre for high stability or POLYelast with very high performance when deformed during assembly.
Manufacturing process: The seals are injection moulded, in a one step process for TPE rubber and a two step process for rubber.
