Internal mixer 350 Sx is mainly used for elastomers

Due to its special design, the internal mixer 350 Sx is mainly used in the rubber and caoutchouc industry for mixing and compounding tasks or for material testing. The upper and lower half of the mixing chamber can be opened like a jaw in order to facilitate removal of the sample material. Special seals prevent the leakage of fine-particle fillers like carbon black or silica.
