Kistler, are fascinating materials known for their light, airy, and translucent appearance and are considered one of the finest insulation materials available today. Aerogels have pores in the range of less than 100 nm in diameter. This morphology results in an ultra-low-density (about 0.0011 ...

What Are PFAS?
PFAS stands for Per- and Poly- Fluorinated Alkyl Substances. PFAS are a large group of complex synthetic chemicals that have been used in the industry and consumer products around the world since the 1950s. They are used to give water, oil, and dirt repellent effect in various everyday products such as non-stick cookware, water-repellent clothing, stain resistant fabrics and carpets, cosmetics, firefighting foams etc. Nearly 70% of the PFAS produced worldwide by volume are four chemicals namely PFOS (Perfluoro octanesulfonic acid), PFOA (Perfluoro octanoic acid), PTFE (polytetrafluoroethylene)
