Tretau was founded to accelerate the transition to a decarbonized future. Building on its core technology, the company is establishing a new industry benchmark for electrification. Tretau supports its stakeholders with solutions that enhance operational efficiency, reduce environmental impact, and enable scalable, cost-effective manufacturing.

To deliver on this mission, Tretau has developed DryCycle®, a patented manufacturing process that enables the application of high-performance technopolymers – including PEEK insulation – directly onto magnet wire in a single step, without solvents, additives, or pre-treatments. This cost-effective technology balances the need for resource-efficient production with the electrical strength, thermal stability, and reliability demanded by modern electrified systems. The wire manufactured through this breakthrough process enables the electric machines of tomorrow: more powerful, compact, and eco-friendly.

Since its establishment in 2014, Tretau has emerged as a pivotal figure in magnet wire innovation and production. With an ambitious team of 70+ employees, the company holds 70 patents in 28 countries and has forged partnerships with leading global players in the automotive, chemical, and various other industries.
