Hosokawa Micron B.V. provides the plastics industry with a wide range of process technologies and equipment for the manufacture of (specialty) polymers.
The Vrieco-Nauta® vacuum dryer is the ideal solution for drying after synthesis, applying vacuum and heat to evaporate all liquid components and also to cure the product. If the boiling point of the fluid is higher than the melting point of the polymer, the valuable ‒ normally toxic and flammable ‒ fluid (monomer) can be recuperated in a controlled manner in the condensing step.
The Vrieco-Nauta® dryer can perform a number of consecutive production steps in one piece of equipment without intermediate transfer, which is a big advantage when contamination is a concern. Another advantage of this dryer is that the temperature to which the polymer is exposed can be kept low and no quality loss occurs.
For higher throughputs and a continuous process, a disc dryer can be used.
Vrieco-Nauta® conical screw mixers can mix polymers with additives to enhance product properties, such as flow properties and static discharge. Vrieco-Nauta® mixers can also be used for recycling scrap and trims into virgin material: offline for pre-mixing or online using semi-continuous production.
Many polymers are extruded either to obtain final products or to be cut into pellets. Important for extrusion is that moisture is extremely low, also the virgin polymer is to be fed homogeneously to the extruder. The Vrieco-Nauta® conical screw dryer meets both requirements in one piece of equipment.
The Vrieco-Nauta® conical screw mixer is suitable for the coating of polymers with pigments before extrusion. For coating in continuous processes a continuous paddle mixer can be used.
Solid state polymerization
A very special field of polymer processing is the thermal heat treatment of - for example - PET, also known as solid state polymerization. Hosokawa technology is being used for this type of polymerisation in many installations worldwide. As these processes require higher temperatures, Hosokawa offers process equipment for batch as well as continuous operation. For this the disc dryer and/or paddle dryer can be used.
Polymer producers are continuously developing special products with tailor made properties. These high value products require ever more complex production methods. With our knowledge, equipment and especially our test centre, Hosokawa Micron B.V. is an ideal partner to help develop new polymer production processes.
From pilot plant to production scale
Hosokawa Micron B.V. offers process equipment and technologies from individual units to large scale bespoke system solutions. Our principle is to deliver high performance yet affordable solutions that meet our customers' demands and long term challenges.
