  We study the behaviour of a scalar field coupled to a noncommutative black
hole which is described by a $\kappa$-cylinder Hopf algebra. We introduce a new
class of realizations of this algebra which has a smooth limit as the
deformation parameter vanishes. The twisted flip operator is independent of the
choice of realization within this class. We demonstrate that the $R$-matrix is
quasi-triangular up to the first order in the deformation parameter. Our
results indicate how a scalar field might behave in the vicinity of a black
hole at the Planck scale.
