    Abstract: A multilayer protective tape for rotor blades of wind energy turbines is provided herein. The protective tape comprising a protective top layer comprising a polymer film, and an adhesive bottom layer. The top layer having a continuous surface (S) that is outwardly curved or outwardly trapezoidal such that the tape has a cross-sectional profile having an inner section between first and second edge lateral sections. The inner section comprises up to 30% of the width of the tape and has a thickness (Ti), while the first and second edge lateral sections have a thickness of T1 and T2, respectively, wherein Ti greater than each of T1 or T2, and the thickness (T1 or T2) of at least one edged lateral section is at most 600 μm and the thickness of the inner section (Ti) is at least 330 μm.
    Also provided is a method for applying the tape to rotor blades and a rotor blade protected by said protective tape.
