Manufacture of Polymer Pellets with High Additive Load
In many applications the need for polymer materials with specific and complex property profiles becomes increasingly important. By using functional additives, essential properties like
- thermal stability
- thermal conductivity
- UV-stability
- burning behavior or
- antistatic properties
of polymers and polymer-ceramic composites are adjustable.
Hot-Melt Fluidized Bed Granulation – An Effective Low-Shear Method
However, these required property profiles cannot be provided by typical basic polymers and are only achievable by loading basic polymer materials with additives. Nevertheless, this functionalization is not directly implementable in most cases. High stresses during processing, e.g. extrusion, can lead to segregation or changes of certain properties of the additives. Therefore, these additives have to be transferred into polymeric carrier systems, protecting the functional particles from damages or degradation by any further processing stresses.
Polymers exhibit different melting and solidification behaviors; the solidification temperature during melt granulation is critical for crystal structure formation.
Hot-melt fluidized bed spray granulation basically offers an innovative and effective possibility for low-shear embedding of functional additive particles in polymeric carriers:
- Hot-melt granulation o ers numerous opportunities for product design of polymer pellets with additive load.
- Solid or liquid additives can be embedded homogeneously in polymer pellets.
- Structure of shear sensitive materials is not a ected by spray granulation of hot-melts.
- Very high additive loads can be realised by combined spray granulation and agglomeration, for applied pigment weight fractions of up to 80 % are realizable.
There is a wide variety of process variants based on fluid bed technology or spouted bed technology. We will be pleased to support you in the realization of your product innovations. At the Glatt Technology Center in Weimar, we work with you to determine the optimum process conditions for your product in feasibility trials for product development. Various laboratory facilities and comprehensive analytical equipment are available for this purpose. On our pilot plants, we optimize the process and scale it up reliably to a stable and economical production scale. The results from this form the basis for the design and construction as well as the erection of your fluid bed or spouted bed plant, tailored to your requirements. As an alternative to our own process technology, we offer you the outsourcing of your production by means of contract manufacturing at Glatt.

By using functional additives, essential properties like thermal stability, thermal conductivity, UV-stability, burning behavior or antistatic properties of polymers and polymer-ceramic composites are adjustable. The Poster shows that solid or liquid additives can be embedded homogeneously in polymer pellets. The structure of shear sensitive materials is not affected by spray granulation of hot-melts. Very high additive loads can be realised by combined spray granulation and agglomeration, for applied pigment weight fractions of up to 80 % are realizable.
