Fillite Oilfield 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 material.


  • Reduced weight.
  • Increased filler loading.
  • Better flow characteristics due to the spherical shape.
  • Reduced water absorption.
  • Improved insulation value.
  • Less shrinkage and warping.

Field of application

  • Low density cement slurries.
