Plastic foam - Import export

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.

Advanced Nova Swiss technology allows high-precision gas mixing under controlled pressure. The servo motor ensures state-of-the-art pressure regulation that is optimal for the respective application. This results in maximum precision for the injection process and ensures exact gas metering at the required pressure. Benefits : High flow rates Maximum pressure precision Low maintenance costs No daily re-adjustment required Faster start-up after interruptions. Thereby less waste during the start-up process. No compressed air supply required. Contamination-free gases thanks to diaphragm technology. The Nova Swiss gas injection unit does not require compressed air, as it is the case with pneumatic amplifiers. The integrated lubrication unit allows the system to be operated at very low speed, which in turn enables the dimensioning of extremely small quantities.

In-line fault testing on single wires and cables during the extrusion or rewinding process has become standard procedure today. ZUMBACH Spark Testers can be used to test the most diverse range of cable products as per international standards, like IEC 62230, UL 1581, UL 2556 and other. Integrated ports allow communication for easy integration with quality control systems (e.g. USYS). According to various applications, ZUMBACH offers Mains Frequency, Direct Current and High-Frequency spark testers. Typically they are installed at the end of the cooling trough in extrusion lines or in rewinding pro- cesses and detect the smallest defects and bare patches in the insulation or sheathing of electrical wires and cables. Properties Testing with sinusoidal alternating voltage and mains frequency or low frequency Bare patch and pinhole detection Electrodes for product diameters up to 250 mm Models with up to 40 kV AC or 28 kV DC available
