PORAVER® EXPANDED GLASS

The innovative lightweight aggregate from post-consumer recycled glass

Poraver® expanded glass is a multifunctional lightweight aggregate from post-consumer recycled glass for building materials and industrial products. The small and light spheres are made of foamed glass with tiny pores that form a closed cell structure. Poraver® is industrially manufactured by a special process, providing consistent quality and a reliable raw material solution for various industrial applications.

BENEFICIAL PROPERTIES

Poraver® offers many possibilities for optimizing products to make them lighter, with more yield, easier to use or more environmentally friendly. Our creamy white mineral lightweight aggregate offers densities from 180 kg/m³ (11.2 lb/ft³) and is available in different grain sizes from 0.04 mm to 8 mm. Thanks to its beneficial properties, Poraver® is versatile for different industries.

Our raw material is recycling glass

Poraver® is pure glass! The raw material for Poraver® is post-consumer recycled glass, which for technical reasons the glass industry can not use to manufacture new products. Poraver® utilizes this cullet and closes a gap in the glass recycling process. By using Poraver® you are making an active contribution to the environment and at the same time protecting natural resources.

ROUND GRAINS FOR HIGHER PACKING DENSITIES

Among all particle shapes the spherical shape has the lowest surface area to volume ratio and therefore related advantages. Compared to irregularly shaped fillers higher packing densities and higher filler contents can be realized. The voids between the large Poraver® spheres are filled by smaller Poraver® grains, resulting in fewer gaps. This allows the reduction of binder and higher strengths can be achieved. More benefits

The Original from the Inventor

30 years ago Dennert Poraver GmbH was the first company which developed a process to manufacture expanded glass from post-consumer recycled glass. This patented process was the beginning of the Poraver® success story.

Of course we had to find an appropriate name for this innovative product. The French terms “Pores” for pores and “verre” for glass formed the name: The brand PORAVER was born (pronounced “Pora-Ver”). Common names for expanded glass granules are also foam glass granulate, mineral foam granules, mineral lightweight filler, microspheres or expanded glass beads.

THE PORAVER® GRAIN SIZES

Poraver ® expanded glass granulate is available in seven grain sizes starting from 0.04 mm to 8 mm (Mesh # 400 to 5/16″) and delivered in bags, super-sacs (FIBC) or also as bulk material.
