PROMIX SOLUTIONS AG

Microcell foam extrusion systems from Promix are used for a wide variety of applications and for almost all polymers. Thanks to the production of very homogeneous microcellular foam structures, high-quality foam products with very low densities and excellent mechanical properties can be produced. Physical foaming can reduce material consumption and thus costs by an average of 20%. This not only saves money but also has a positive impact on the environment. Promix Foam extrusion systems set standards in the production of microcellular foam products with very homogeneous cell structure and high process consistency. The systems operate with environmentally friendly blowing fluids nitrogen or CO2 and are easy to integrate into existing or new extrusion lines. Depending on the application, density reductions of 5 to over 70 % can be achieved.The technology can be used for packaging films, sheets, foam core and corrugated pipes as wellas profiles, cable sheating, blow molds and blown films.

Promix gas dosing stations for physical foaming have been specially designed and developed to meet the needs of foam extrusion. Promix gas metering technology is characterized by high dosing accuracy, reliability and amazingly simple operation. Promix gas dosing stations meet all the requirements of a modern gas metering system for foam extrusion. These include high-precision mass flow control, process visualization by means of trend charts, operator-definable operating limits, data acquisition, and synchronization of the dosing rate with the extruder output. Implementation in the extruder control system via fieldbus system is also possible. •,Mass flow from 1 g/h up to 20'000 g/h •,Dosing pressure up to 680 bar

The Procell nucleation additives developed by Promix are specially adapted to the Microcell foam extrusion of plastic melts. They lead to microcellular foam structures, a key factor for high mechanical strength of the foamed product. Homogeneous, very fine-cell foam structures are the key to high mechanical strength. Promix has developed specific Procell nucleation additives. These are specially adapted to the Promix Microcell foam technology and lead to microcellular foam structures. The additives can be used in foam extrusion and light foam extrusion for many polymers such as PP, PET, PE, PS, ABS, PLA and are suitable for food contact applications. Contact us for a test sample.

Promix specializes in demanding cooling and heat exchanger tasks such as cooling and heating of viscous or decomposition-sensitive media / plastic melts. The Promix P1 heat exchanger is the unique combination of a very efficient static mixer and a powerful cooler. The novel patented technology opens up completely new process engineering possibilities in the cooling and heating of plastic melts and other viscous fluids. The simultaneous mixing and cooling processes in the P1 allow for very efficient cooling and heating without the formation of deposits or the risk of product decomposition. Advantages Promix P1 heat exchanger Very efficient cooling of polymer melts close to the solidification point Precise temperature control and uniform temperature distribution at the outlet Very robust construction Extremely gentle cooling and heating of residence time critical fluids Unique self-cleaning behavior Reliably scalable from laboratory test to production scale Test options

Mixing nozzles and static mixers from Promix ensure excellent melt homogeneity and efficiently prevent color streaks or flow lines. Quality problems in injection molding are often solved by modifying the process parameters. Masterbatch concentration and back pressure must be increased, which makes production costs more expensive. This does not have to be the case! Mixing Nozzles from Promix ensure excellent melt homogeneity. Color streaks or irregularly distributed additives in the component are a thing of the past. The ready-to-connect mixing nozzle is installed on the injection molding machine replacing the standard nozzle. Contact us for a mixing nozzle to test.

Insufficient surface quality, long cooling times, uneven thickness tolerances or other quality problems often limit maximum production output. Promix melt blenders eliminate these limitations sustainably and lead to significant cost savings. Would you like to optimize your extrusion process? Improved melt homogeneity and a more uniform melt temperature create tighter thickness tolerances and better surface quality. And quite often, it can also increase production throughput. Promix offers you highly effective static mixers and melt blenders at low investment costs. They are supplied ready for installation, including heater bands and holes for pressure and temperature sensors. The melt blenders are usually installed downstream of the screen changer & gear pump, and upstream of the die. The very short installation length allows easy retrofitting in existing extrusion lines.

Promix supplies key components to optimize the production of light foams such as XPS insulation boards, XPET construction boards, XPE foam films, etc. Thanks to the improved cell structure, the foam density can be further reduced, and the throughput of the plant increased, resulting in significant cost savings in production. Replacement of iso-butane for the sake of the environment Iso-butane and other hydrocarbons are excellent blowing agents for high expansion foam production.However, they are also highly harmful to the environment and highly flammable, which increases the production risk. Promix gas dosing stations in combination with other retrofittable process engineering components enable at least a partial switch to the non-flammable and environmentally neutral gases CO2 and nitrogen. Your optimization potential ,Improved mechanical product properties ,Lower foam density ,Replacement of hydrocarbon blowing agents with CO2 and nitrogen ,Increased line throughput
