First-class technology for the production of contact adhesives and melt adhesives

Continuous Production of Pressure Sensitive Adhesives and Hot Melt Adhesives

Adhesives are characterized by the fact that they are able to bond parts made out of all kind of material. Adhesives for technical applications are highly developed compounds, especially designed for these requirements.

Coperion’s extrusion systems have been used successfully for many years in the production of pressure sensitive adhesives and hot melt adhesives.

Through highly accurate feeders of Coperion K-Tron the polymers and additives are fed gravimetrically, individually or pre-mixed into the infeed barrel of the twin screw extruder ZSK Mv PLUS. After plasticizing/masticating and compounding of the different polymers and additives, the resins (solid or liquid) and softeners/oils and fillers are incorporated.

Process steps such as the devolatilization of air and volatile components or the straining of the finished compound follow.

Today the majority of adhesives are still produced in batch processes. Due to the fluctuation in quality and in many cases high efforts for cleaning, more and more producers are switching from the batch process to the continuous process on Coperion’s ZSK co-rotating twin screw extruders.
