The first water soluble cast material SysTherm® Cast guarantees a tailored solution that is perfectly adapted to the SysTherm® polymer. SysTherm® Cast´s new chemical formulation ensures that in combination with the SysTherm® polymer no separator is necessary. Now, you can avoid breaking or cracking the mold from the earpiece. Microcracks in the earmold become a thing of the past. SysTherm® Cast can also be used with silicone materials.
