Physical foaming - Import export

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.

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 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 RF 400-AL high-frequency cable from bda connectivity is suitable for radio data transmission, WiFi and other applications of 50 Ohm technology and is specified for use up to 6 GHz (5G). The CCA inner conductor is surrounded by an insulation layer of physically foamed Cell-PE, double-laminated aluminium foil and a braid of tinned copper as the outer conductor, covered by a black PVC jacket. This ensures UV resistance and good laying properties.

BS Shockpad is a specialized polyethylene foam material, chemically cross-linked for enhanced performance. Through a combination of heat expansion and the addition of chemical inflators and cross-linking agents during extrusion, this foam material achieves advanced chemical and mechanical properties. Compared to physically cross-linked polyethylene foam, the cell structure of BS Shockpad is larger, resulting in a slightly less smooth surface. It is widely used in applications that require sound, heat, humidity insulation, and shock protection.

Polyethylene foams have applications in countless industries. In the offer of our company, you can get flame-retardant, electro-conductive, anti-static and PE foams of various hardnesses. We process this type of raw material in rolls and blocks. PE foams are especially suitable for sealing and insulation. They are also resistant to many chemicals/solvents and have good resistance to UV and ozone. Polyethylene foam is used in automotive, construction, industrial, medical and orthopedic technology, electronics and many other sectors. We have: Physically cross-linked polyethylene foam with closed cell structure (corresponds to the guidelines of the automotive industry US FMVSS 302 and EU guidelines - RoHS 2002/95/EC) Chemically cross-linked polyethylene foam (financially favorable sound insulation and vibration damper) Non-cross-linked polyethylene foam with closed cell structure (ideal for protective packaging e.g. TV, computers, electronic or medical devices)
