Biomineral Silica Aerogel – Reinventing Silica Aerogel
Biomineral silica aerogel as next-generation silica aerogel material for space savings and energy efficiency combined with fire resistance and easy, dust-free handling
Our biomineral silica aerogels are unique hybrid materials derived from non-food biomass and silica.
Thanks to our energy-efficient production technology and green raw material base, we anticipate an excellent sustainability footprint footprint.
With our biomineral silica aerogels, we are setting new standards in sustainable material technology, offering solutions for numerous industrial applications.
Biomineral Silica Aerogel LSMA
Biomineral Silica Aerogel LSMA is a next-generation silica aerogel based on silicate combined with an innovative biopolymer binder formulation. The typical dust release of silica aerogels is prevented while the intrinsic properties of silica such as fire and temperature resistance are retained. It is the perfect solution for demanding insulation and high-temperature applications, offering a unique combination of sustainability, performance, and adaptability.
The material is available as hydrophilic or hydrophobic grades.
An application test with the material is currently being conducted in the CUBE, the worldwide first carbon fiber-reinforced concrete building. More information is available here.
The material is currently in development. Sample quantities are available at the pilot scale. We posted on this in 05/25.
