A wireless terminal with a reduced Specific Absorption Rate peak value and a method for reducing an SAR peak value by using the wireless terminal are disclosed. The cleaning surfaces lie opposite each other and border a cleaning gap between each other. This material comprises a multiplicity of particles. Preferably, the inner, high density, center component is produced without the use of a crosslinking agent or coagent, which is the reaction product of an unsaturated carboxylic acid or acids and an oxide or carbonate of a metal such as zinc.
