The unique combination of Poraver®, poraSpheres® and plastics takes the best of two material worlds and creates high-quality compounds with Poraver® that are highly efficient, lightweight and preserve resources. Numerous users are already benefiting from the many advantages of the intelligent glass-polymer compound.
We are specialists in the modification and processing of thermoplastics with our in-house products Poraver® and poraSpheres®, both made from post-consumer recycled glass.
In our development work at our modern, well-equipped Kunststoff Center, we focus on customized solutions for individual product and project requirements - and in the shortest possible time. We are guided by current trends, incorporate new ideas and take market requirements into account.

- High availability due to in-house production
poraComp® is the clever combination of Poraver® expanded glass or poraSpheres® hollow microspheres and thermoplastics. By using our functional fillers made of resource-saving recycled glass, it provides the advantage in sustainability with unique properties.
Recycled glass (l.) and poraSpheres® or Poraver® (m.) become poraComp® (r.).
Comparison poraSpheres® and Poraver®
The schematic representation of a cut poraSperes® grain illustrates the structure with only one single cavity.
The image of a Poraver® grain (1-2 mm) taken with a scanning electron micro-scope shows its multicellular internal structure.
The relative global warming potential or CO2 equivalent is a measure of the relative contribution of a substance to the greenhouse effect over a certain period of time. It indicates how much a certain amount of the substance contributes to global warming compared to the same amount of CO2. For example, the CO2 equivalent for methane is 28 for a time horizon of 100 years, which means that one kilogram of methane contributes 28 times as much to the greenhouse effect within the first 100 years after its release as one kilogram of CO2. In comparison, the CO2 equivalent of Poraver® is 0,68 2).
With poraComp® you get a functional solution that significantly improves the properties and the carbon footprint of your products. By using poraComp® compounds based on polyamide, the CO2 equivalent per kilogram is reduced by 1.1 compared to non-reinforced polyamide. In comparison with glass fiber reinforced polyamide, the reduction is even higher at around 1.6 per kilogram.

The use of sustainable products, the avoidance of waste and the recycling of valuable materials are the focus of society and the plastics industry. Our poraComp® compounds are based on using sustainable fillers - so every kilo of poraComp® saves CO2. The product is even more sustainable when recycled materials are used - this is how we achieve almost 100% recyclate-based compounds.
Die Verwendung von nachhaltigen Produkten, die Abfallvermeidung und die Wiederaufbereitung von werthaltigen Materialien stehen im Fokus der Gesellschaft und der Kunststoffindustrie. Unsere poraComp®-Compounds basieren darauf, nachhaltige Füllstoffe zu verwenden - so spart jedes Kilo poraComp® CO2. Noch nachhaltiger wird es wenn Rezyklate verwendet werden - so erreichen wir nahezu 100 % rezyklatbasierte Compounds.
- Plastics with improved sustainability due to high recycled content
- High performance compounds with reduced density
- Compounds with improved flame retardancy
- Conductive plastics or other special applications
- Scratch resistant compounds for high value applications
- Applications in the construction, automotive, furniture and electrical industries, for consumer products and household appliances, dimensionally stable packaging, transport containers and many more
In addition to our range of compounds, we also offer compounds with tailor-made properties for your special application.
In our in-house R&D poraComp® Center, we develop our unique compounds with Poraver® or poraSpheres® as the starting material. We focus our development work on saving plastics, increasing sustainability through the use of Poraver® and/or poraSpheres®, and specifically improving properties by combining them with other additives.
The formulations are therefore constantly and flexibly optimised for the respective area of application and are very diverse due to different mixing ratios. We currently distinguish between four product families based on poraComp® compounds. What they all have in common is that they are more sustainable due to the proportion of Poraver® / poraSpheres® and thus actively contribute to the conservation of resources.
In unserem hauseigenen F&E poraComp® Center entwickeln wir unsere einzigartigen Compounds mit Poraver® oder poraSpheres® als Ausgangsstoff. Wir fokussieren unsere Entwicklungsarbeit auf die Einsparung von Kunststoffen, die Erhöhung der Nachhaltigkeit durch Einsatz von Poraver® und/oder poraSpheres® sowie der gezielten Verbesserung der Eigenschaften durch die Kombination mit weiteren Additiven.
Die Rezepturen werden daher ständig und flexibel auf das jeweilige Einsatzgebiet hin optimiert und sind aufgrund unterschiedlicher Mischungsverhältnisse sehr vielfältig. Wir unterscheiden aktuell vier Produktfamilien auf der Gundlage von poraComp® Compounds. Allen gemein ist, dass sie durch den Anteil an Poraver® / poraSpheres® ein Plus an Nachhaltigkeit mitbringen und damit aktiv zur Ressourcenschonung beitragen.
