Extrusions - 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.

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.

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.

StaMixCo manufacturers all three commercially proven static mixer designs used for high viscous melt flow mixing of polymers in extrusion service. As with most process equipment, each static mixer design has specific advantages and disadvantages that make it more or less suitable for a specific application and installation. Each type of motionless mixer is discussed below: Process Improvements: Temperature gradients are virtually eliminated. Viscosity gradients are virtually eliminated. Composition gradients of colorant, chemical additives, fillers and regrind are virtually eliminated. Stagnant polymer wall-creep material is incorporated into the bulk polymer stream. Extrusion Applications Static Mixers are used in most extrusion applications including the following: Sheet Blown Film Foam sheet Profile extrusion Co-extrusion Pipe Extrusion Blow Molding Rod & Tubing Wire & Cable Coatings Fiber extrusion & monofilaments Benefits Reduction of color additives with comparable extrudate color density. Even thickness across the entire extrudate width. Streak-free product. Improved quality when using regrind material. Foam cell size and cell distribution uniformity. Improved surface quality Improved mechanical characteristics. Rapid color change-over SMB-R Static Mixer SMB-GXS Static Mixer Mixing of blue and white epoxy resin with the SMB-GXS Static Melt Blender. It improves the melt homogeneity by factor 5-6. SMB-R Static Mixer The SMB-R static mixer for extrusion service (licensee of Bayer AG, Leverkusen, Germany) contains eight (8) very efficient motionless mixing elements that homogenize the polymer melt as it enters the extruder die. The SMB-R mixing elements are considered as high performance design where they create a very high degree of mixing in a short length. The SMB-R mixing elements are virtually indestructible due to their monolithic cast construction where the mixing bars are jointed to each other and to the ring wall via a single molten metal pour. Mixing of blue and white epoxy resins. Empty tube (top)provides no mixing. Eight (8) mixing elements (bottom) provide an excellent mix quality in a short length. SMB-GX Static Mixer Melt Blender The SMB-GX motionless mixer is a design that has been used in melt flow mixing extrusion service for over 25 years. The SMB-GX mixing elements are considered as high performance design where they create homogeneous mix in a short length. It has the same fundamental X-Grid crossing-bar structure as the StaMixCo SMB-R static mixer (Figure #8), but without the support ring around the mixing blade structure which gives the SMB-R its remarkable strength. Since the SMB-GX is manufactured from metal plates that are welded together, virtually any custom static mixer plate thickness, material and diameter can be fabricated to meet process and installation requirements. SMB-H Static Mixer Melt Blender The SMB-H Helical static mixer design pioneered the static mixing industry and has been used as a viscous static mixer on extruders for over 37 years. The Helical design is considered a low mixing performance-long length-low pressure drop motionless mixer as compared to the later developments of high performance static mixers such as the SMB-R and SMB-GX which have become the technology standards in the industry. StaMixCo manufactures SMB-H static mixers by advanced proprietary manufacturing technique where the entire unit is machined from a solid rod of bar stock material without welding. This machining process allows for custom static mixer fabrication in virtually any L/D twist, in very small sizes, with very high strength, straight and true dimensioning and with a RMS 12 mirror polish surface finish which is a much improved surface finish as compared to the traditional 32 RMS finish for the twisted and welded design.
