Type of filament is more permanent than other filaments and can maintain the cell structure even after the cell dies is  Intermediate filaments
The intermediate filaments are a permanent part of the cytoskeleton and help provide structure for the cell. They are also essential in anchoring the cell to other cells, called cell cohesion, and to the extracellular matrix.
Intermediate filaments are more permanent fixtures of the cytoskeleton than are the other two classes. They reinforce cell shape and fix organelle location.Intermediate filaments have a diameter of about 10 nm, which is intermediate between the diameters of the two other principal elements of the cytoskeleton, actin filaments (about 7 nm) and microtubules (about 25 nm). In contrast to actin filaments and microtubules, the intermediate filaments are not directly involved in cell movements. Instead, they appear to play basically a structural role by providing mechanical strength to cells and tissues.
