Feldspar as a mineral and classify feldspars as mainly as albite, microcline, orthoclase and amortise. Sodium, potassium, and mixed feldspars can be further distinguished based on the type of alkali they contain. Feldspar is a common mineral raw material used as fluxing agents in Ceramic and Glass making and to some extent as a functional filler and extender in Paint, Plastics, Rubber and Adhesive Industries. Its dispensability, chemical inertness, constant pH, strong resistance to abrasion, low viscosity at high filler loading, fascinating refractive index, and resistance to icing are all advantages of feldspars.


  • Silfermin FLS: Known as Feldspar and is produced from naturally occurring combination of alumina and silicate having mix oxides and no free crystalline silica. Silfermin FLS is a specially designed extender to enhance the performance of Printing Inks. Silfermin FLS has hard and angular particles create a rigid reinforcing network, possesses hardness properties which maintain desirable scratch and abrasion resistance in coatings for increased service life.
