Tougher. Efficient. Durable. Optimized.

Kenospheres® improve material strength, enhance thermal properties, and ensure lasting durability.

The multi-purpose filler

Product Overview

Kenospheres® are high-performance hollow ceramic microspheres made from alumino-silicate materials, offering an innovative alternative to conventional fillers such as silica, calcium carbonate, talc, and clay. Their unique composition and structure make them ideal for a wide range of demanding industrial applications, enhancing product performance while reducing weight and material costs.

The spherical shape of Kenospheres® brings several key benefits, including higher filler loading capacity, improved flow properties, and reduced shrinkage and thermal expansion. This structure ensures smooth integration into various formulations, making Kenospheres® suitable for multiple production methods such as molding, extrusion, and coatings.

Composed of chemically inert, water-resistant, and non-combustible ceramics, Kenospheres® provide outstanding durability and stability. Their non-porous nature prevents resin absorption, ensuring consistent viscosity and a long shelf life. Compatible with most resin systems, Kenospheres® deliver superior mechanical strength, thermal insulation, and process efficiency across diverse industries.

White Paper: Renovation Wave

Only one percent of Europe's building stock undergoes energy renovations annually, which is insufficient to meet climate protection goals. To address this, the European Commission has introduced the “Renovation Wave” initiative, aiming to at least double the renovation rate over the next decade. Our whitepaper offers detailed information on the background, priorities, and measures of this initiative.

White Paper: Renovation Wave

Only one percent of the building stock in Europe is currently energetically renovated every year - too little to achieve the climate protection goals. The European Commission has therefore launched the “Renovation Wave” initiative, with the aim of at least doubling the renovation rate in the next ten years. Our white paper provides information on the background, priorities and measures.
