Fillite Standard Grades

Hollow ceramic microspheres

FILLITE is a glass hard, inert, hollow silicate sphere.

FILLITE is primarily used to reduce the weight of plastics, rubbers, resins, cement, etc., but also imparts further benefits in many situations. Many of the advantages from the use of FILLITE , including increased filler loading and improved rheology, are directly attributed to the spherical nature of the mineral


  • Reduced weight.
  • Increased filler loading.
  • Better flow characteristics due to the spherical shape.
  • Improved physical properties in moldings, castings and laminates.
  • Reduced water absorption.
  • Improved flame retardance.
  • Improved chemical resistance.
  • Good crush strength.
  • Less shrinkage and warping.
  • Grey colour.

Fields of application

  • Refractories.
  • PVC flooring.
  • Brake linings.
  • Phenolics and epoxies.
  • Cast polyesters.
  • Synthetic marbles.
  • Syntactic foams.
  • BMC, SMC and FRP.
  • Low density, shotcrete.
  • Wallboard joint compounds.
  • Automotive sound-damping sheets.
  • Oil well cements.
