PURPOSE: A composition for a protection cover is provided to continuously manufacture a protection cover by a extrusion molding method having a reduction effect of a production cost without manufacturing the protection cover through a press compression. CONSTITUTION: A composition for a protection cover consists of a polyethylene, plasticizer, CaCO3, stabilizer, flame retardant, an activator, and a filling material. A manufacturing method of a protection cover for an LIP part by using the composition comprises a step of conducting extrusion by putting the composition into a cylinder; a step of continuously drawing solid material with a protection cover shape; a step of cutting the solid material by a specific length; and a step of cutting the cut solid material into s specific size.
