Jolly Mixer by Comac are popular units used in many laboratories. With a Comac Jolly Mixer, you may prepare mini-batches of product using very limited quantities of base polymers and pigments for each batch. The quality of product samples obtained by a Jolly Mixer is usually even better than actually achieved in real extrusion lines.Jolly Mixers process raw materials by means of high shear-rate rotors.
Comac propose a standard version having a mixing chamber that is not heated and a thermoregulated version having electrically heated and water cooled jacketed mixing chamber. The standard version is suitable for products based on polyolefines, PBT and polymers like ABS.
The thermoregulated version with heated anc cooled mixing chamber is instead recommended for products based on highly crystalline polymers such as PA.
