Poraver® and polymer combined:
poraComp® glass-polymer-compounds

poraComp® are high-quality thermoplastics, modified with our inorganic, odorless lightweight fillers based on post-consumer recycled glass. Depending on the requirements, our recycled glass based fillers are incorporated in the form of Poraver® expanded glass microgranules, poraSpheres® hollow glass microspheres or in combination with other fillers and reinforcing materials. In the production of poraComp®, a wide variety of thermoplastic matrix materials such as polyolefins (PE, PP), technical plastics (PA, PBT, POM, TPE) or even bio-based plastics (PLA, PHA) can be used. High filler content of up to 50% by volume are possible. For special applications, such as electrically conductive plastics or halogen-free flame retardant compounds, we develop tailor-made solutions for our customers and partners.

poraComp® applications
for innovations and sustainable solutions

The use of sustainable products, waste avoidance and the recycling of valuable materials are the focus of todays society and the plastics industry. Therefore, we focus on recycled glass and the use of recycled plastics as matrix material whenever possible. The poraComp® compounds produced from these raw materials consist of up to 100 % recycled material.

Possibilities of applications
• Products 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
• Applications in building & construction, automotive, furniture and electrical industries, for consumer goods and household appliances, rigid packaging, transport containers

Based on your requirements, we will design your compound formulations. For special applications, we develop customised solutions for our customers and partners.

poraComp® advantages

poraComp® advantages

Besides the high sustainability through the use of secondary raw materials, poraComp® offers versatile synergy effects. The unique combination of Poraver® expanded glass and thermoplastics gives you the best of both material worlds. The poraComp® compounds convince by high quality, outstanding properties and CO2 savings compared to virgin materials. This exceptional combination of advantages enables the development of next generation products with a unique focus on sustainability.

Weight reduction, sustainability, increase in efficiency
• Weight reduction of components by up to 40 %
compared to compounds with standard fillers
• Reinforced plastics with high recycled content
• Process cycle times shortened by up to 30 %
• Higher yield due to reduced compound density

Flexible usage
• Substitution of compounds with standard fillers or use in combination
• Processing on standard equipment (sheet, pipe or profile extrusion as well as injection molding and 3D printing)

Improvement of the component characteristics
• Minimized shrinkage and reduced warpage
• Improved chemical resistance
• Improved thermal properties
• Increased flame retardancy
• Modification of electrical characteristics
• Optimization of stiffness
