Extrusion International 5-2025-USA

52 Extrusion International 5/2025 К 2025 signi cant material savings. This not only reduces production costs but also protects the environment. Promix Microcell Technology is mainly used for lms, sheets, foam core pipes, pro les and cable sheath - ing and works for almost all poly- mers. In addition to saving polymer, new product properties associated with foaming, such as weight reduc- tion, improved noise or heat insula- tion, better shock/impact absorption, light-diffusing optics or other visual and haptic effects, are often an ad- ditional incentive for using Promix Microcell Technology. At K, Promix will be showcasing relevant key components and provid- ing information on the possibilities within the speci c elds of applica - tion. One promising new eld of ap - plication is the foaming of mono la - ments. Promix is currently developing foamed mono laments for arti cial grass together with an industrial partner. Microcell technology is available for both, newly planned extrusion lines and as a retro t solution for ex - isting lines. To date, more than 350 industrial references are on the mar- ket and various machine manufactur- ers are successfully integrating the technology into their lines. The gas dosing system, the heart of the physical foaming process, has been equipped with a modernized graphical user interface for even easier operation. In addition, an im- proved grade of Procell nucleation additives is available, ensuring even ner cell structures. In higher dosag - es, it also acts as a foaming additive. This can be helpful in extrusion lines with very low throughputs or for pre- liminary testing, since additive foam- ing does not require any changes to the extrusion line. The experts at Pro- mix will be happy to advise you. The increasing use of recyclates and raw materials from different sources makes it more and more dif cult to keep extrusion processes under con- trol. The inline viscometer "Visco-P" measures the actual viscosity under processing conditions and in real time directly in the melt stream, without any bypass or loss of material. The maintenance-free measuring mod- ule, which is tailored to the applica- tion, homogenizes the melt without the risk of clogging, deposits or de- composition. The Visco-P is therefore ideal for recyclates as well as lled and shear-sensitive materials. At the K trade fair, Promix will be demonstrating how Visco-P can be used to measure and control the IV value during PET extrusion. The sys- tem has a closed control loop into which a dosing device can be inte- grated As soon as the IV value mea- sured in the production process falls below the target value, the software triggers the dosing of an IV enhanc- er until the quality of the melt has reached the desired level again. The same logic is possible in PP recycling by dosing respective chain extenders. Trend evaluations and reporting tools enable the measurement re- sults to be recorded with statistical analysis. User-selectable limit values for the viscosity trigger an alarm and show the operator current deviations from the target value. This means that corrective measures can be tak- en immediately, even without a con- trol loop. The Visco-P inline viscometer is compatible with all common extrud- er types and almost all polymers and can be retrofitted to existing sys- tems. All common interfaces are op- tionally available to flexibly network the new products with Industry 4.0 platforms.
