According to Dr Jürgen Köhler, designated CEO, SGL, the sale is part of the strategic repositioning of the group.
"In future, we will in the carbon fibre business focus more strongly on our core competency of material development and production," states Köhler.
SGL Rotec was formed in 2008 as a joint venture between the SGL Group and Abeking & Rasmussen Schiffs- und Yachtwerft AG. SGL took a 100% stake in SGL Rotec in 2012.
SGL Rotec has been using materials such as carbon fibre in conjunction with semi-automatic machining technology to produce lighter weight, slimmer and more stable rotor blades for offshore applications and low-wind areas.
SGL reports that the new owner (as yet unnamed) is planning to expand production at the SGL Rotec site in Lemwerder, Germany, which currently employs approximately 550 people.
SGL will continue to supply the company with carbon and glass fibre materials.
The acquisition is expected to be completed by 31 December 2013. The new owner will be unveiled in January and the company will operate under the name Carbon Rotec.
The purchase price has not been disclosed.
