  • the mixed layer is preferably an elastomeric layer which hardens in particular to a modulus of elasticity of 0.05-0.5 GPa, thereby obtaining a rubbery elasticity.
  • a cork, wood or leather impression are underlined very well.
  • Such a covering element is very well suited as a wall covering element.
