Leading masterbatch producers value Clextral twin screw extruders for their flexibility and reliability in manufacturing premium pigment concentrates.Clextral systems offer significant advantages:
Optimum Product Quality
?Proprietary screw profiles assure efficient dispersion of pigment
?Pigments may be pre-mixed with the polymer,added from individual feeders or injected at later stages in the polymer melt
?Powerful gearbox transmits maximum screw torque creating optimum shear for
homogenous mixing.Short residence times protect heat sensitive materials.Process Flexibility
?Sliding opening of the barrel allows immediate access for cleaning and screw reconfiguration reducing downtime between batches
?Dies are quick change design and are available with hydraulic or mechanical opening device ?Self wiping screws facilitate easy cleanout for colour changes.Grinded face screw elements prohibit material infiltration between screw sections.Output from 5 to 350 kg/h

M ASTERBATCH L ABORATORY E XTRUDER BC 21
The BC 21 extruder is an incomparable tool for product development.With output from 2 to 30kg/hr ,this unit provides quantifiable results with less waste.
The H version allows immediate access to the screws (less than two minutes) for product sample,reconfiguration or examination of the evolution of the mix along the screw profile.
A complete assortment of screws,mixing
elements,feeders (dry and liquid injection ports)and dies are available.
Hydraulic barrel opening allows immediate access for product change,cleanout and maintenance.
Continuous processing of high quality pigment
concentrates requires special consideration.Clextral twin screw processing equipment offers dedicated features for these specific requirements.
A premix of polymer and pigment is introduced through the extruder feeder.Screw flights at feed stage are open design to provide high free volume for optimum
feeding.Screw profile can include various thread depths allowing equal distances between screw axes,as well as mixing elements in monolobal,bilobal or trilobal designs to provide rapid melt and thorough pigment dispersion.Additional pigment,lubricants,stabilizers or other agents may be added through dry feed ports or injected in liquid form at various stages along the barrel.Volatile components are vented through barrel ports under vacuum.
The processed polymer pigment concentrate is formed by a high capacity die.Quick change die designs offer hydraulic or mechanical opening with simple electrical connection for heating elements of the die.
