The paper is devoted to a detail study of charging and discharging processes of 5 {mu}m melamine formaldehyde resin grains that could partly simulate porous aggregates observed in the space. We present unusual charging properties of these grains influenced by both low- and high-energy electron beams of various current densities. The increase of the second crossover potential for highly negatively charged grains was derived from equilibrium charging characteristics.
