PSA (Solvent-Free)

A customised solution for any challenge

When it comes to successfully producing and compounding pressure-sensitive adhesives (PSA), there are several decisive factors: the targeted meltability of different formulation components, the precise control of reactions, an extruded material of equal homogeneity and viscosity, effective cooling of the adhesive mass and high degassing quality to optimise subsequent processing.


The solution: The ENTEX Planetary Roller Extruder

PSA stands for pressure-sensitive adhesives that form a permanent bond with the application of even slight pressure. With the continuous direct extrusion of pressure-sensitive adhesives, the challenge lies in combining various substances with different chemical and physical properties (or thermal and mechanical stress limits) according to a specific formulation. To do this, many established adhesive manufacturers employ the reliable compounding technology offered by the ENTEX Planetary Roller Extruder (PRE). Thanks to its individually configurable modular construction, the Planetary Roller Extruder can also handle the complex compounding processes required for pressure-sensitive adhesives.
