Promix Solutions - Application examples


XPS, XPE, XPP foams - Info >>>

Key components for the production of XPS, XPE, XPP, XPET low density foams
Promix offers relevant key components to optimize production of low density foams such as fabrication of XPS insulation boards, XPE foam film or XPP, and EPE thermoforming sheet. Implementing Promix key equipment generally results in lower foam densities, improved cell structure and an increased line output, leading altogether to significantly lower production cost. Whether it is a tandem or long twin screw line, thermal insulation boards, packaging film or insulation for tubes or pipes: we will analyze your current line concept and propose a solution to increase your profitability.

P1 Cooling Mixer - Info >>>
Promix P1 Cooling mixer technology is a unique combination of a highly efficient static mixer and a powerful cooler. The novel patent-registered technology pushes the boundary when it comes to cooling of polymer melt and other viscous fluids. The simultaneously occurring mixing and cooling effects in the P1 cooling mixer allow a very efficient cooling very close to the solidification point of the melt without the risk of freezing or building of deposits. The melt temperature is homogenized over the whole cross section. Depending on process requirements, the ideal melt temperature can be exactly adjusted and kept constant over time.

Q1 Annular die for the production of EPS (XPS), XPE, XPP foam films - Info >>>
The annular die technology has a major influence on the quality of EPS (XPS), XPE and XPP foam films. Promix Q1 annular die technology unifies 20 years of experience in designing and manufacturing of annular foam dies. The particular construction of Promix Q1 annular dies (patent pending) allows further reduction of foam density and film thickness tolerances. This leads to significant savings in terms of raw material and production costs.

Inline viscosity measurement - Infos >>>

Viscosity measurement, accurate and inline - True real time quality control
Control the production quality of your extrusion line with Promix Visco-P continuously and in real time. Avoid poor production quality issues and scrap. Visco-P is a true inline viscometer which measures viscosity directly in the melt stream and requires no bypass. The Visco-P continuously monitors raw material quality and process conditions. Convince yourself. Ask us for a test unit.

Promix Solutions - Promix® Visco-P for accurate inline viscosity measurement in extrusion
Promix® Visco-P for accurate inline viscosity measurement in extrusion

Your benefits
• Continuous real time control of raw material quality and process conditions
• Very accurate inline viscosity measurement without bypass
• Suitable for all viscous fluids
• MFI / IV-calculation mode
• Will be used in combination with Promix static mixers leading to additional value by improved melt and
  temperature homogeneity

How it works
A special Promix static mixer module, installed in the extrusion line, is the physical point for measuring process variables. The calculated results are displayed continuously and in real time on an industrial PC with touch screen. In addition to measuring the melt viscosity, the Visco-P will also calculate the MFI or IV value of the real melt.

The Promix static mixer module creates excellent blending of the polymer melt which improves thermal homogeneity and surface quality, reduces thickness tolerance variations of the extrudates, and often leads to an increased output rate. Visco-P is in operation in many applications such as PET and PE extrusion and for the processing of polymer melts containing blowing fluids.

• Narrow residence time distribution
• Short installation length
• Low pressure drop

Melt Cooler for highest efficiency

Promix Solutions - Melt Cooler for highest efficiency

Melt Cooler concept
In cooling processes viscous fluids tend to deposit at the cooling wall sections (fouling) leading to reduced cooling efficiency. In the Promix Melt Cooler (PMC) the melt flows in a single stream through the cooler. The cooling media flows in special pipe bundles arranged similar to those of the Promix mixing elements. The intense mixing together with the very high heat exchange surface area leads to effective cooling with very limited risk of fouling. Due to a void volume of about 75 % the resulting pressure drop in a PMC is rather low. The PMC can as well be used for gentle heating with only small temperature difference between heating media and fluid.

New product

New gas dosing model

Promix supplies CO2 and N2 gas dosing systems, which were especially developed to suit specific needs in foam extrusion. The devices are characterized by an extremely high dosing accuracy, reliability and easy operation.

With the NC350, Promix is expanding its portfolio with a model that can dose both, nitrogen and CO2. Further characteristic of the NC350 is its large dosing range from 10 - 10'000 g/h.

This makes the unit suitable for use in R&D as well as in traditional production environment. All gas dosing systems were redesigned in autumn 2019. Accessibility was improved and the units were given a new and more streamlined appearance.

Sustainability

Eco-rPET reduces plastics consumption in packaging
Packaging solutions made from Eco-rPET are 10% to 20% lighter than conventional PET packaging. Depending on the application, they can be manufactured translucent or in any desirable color. The pearlescent effect gives the packaging a very elegant and high-quality look and feel. Thermoformed trays and cups made from Eco-rPET feature excellent rigidity and are insensitive to scratch marks making them suitable to safely stow berries or other delicate foods. This helps not only to reduce food waste but also protects the environment, as each produced tray uses 20 % less plastic. It goes without saying that lower plastics consumption is significantly cutting manufacturing cost.

Eco-rPET packaging can be produced from recycled bottle flakes and is fully recyclable after being used itself. It can be manufactured on any existing or new PET sheet extrusion line by incorporating Promix technology. By adding smallest amounts of environmental friendly gases, microcells are generated, resulting in a lighter product weight. Promix supports film and packaging producers worldwide throughout the whole process: from planning to implementation to commissioning.
