Instead of an extruder module, a kneader can be equipped on de base module. This is a system with two parallel rods optimized for compounding. Several polymers and additives can be compounded on a small scale (appr. 70g per batch) to provide material for analyses such as DSC, RDS and density. While measuring the torque, optimal shear for mixing polymers can be determined. For large scale compounding experiments we recommend our ZSK30.
