The materials and products used in transport vehicles require utmost quality and strict certification. It does not matter whether the products are for comfort or serve a practical mechanical purpose. REX acts as a second supplier and thus occupies an important link within the supply chain. In aviation, REX friction and sliding materials ensure the comfortable positioning of headrests, armrests and backrests, but can also be found in control elements in the cockpit, in hydraulic actuators for cargo doors and in the control elements of rudder surfaces. REX products also ensure smooth opening and closing of doors in suburban trains and subways.
