Product Description

Introduction

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.

Characteristics

  • Lightweight
  • Free-flowing
  • Gray in Colour
  • Spherical
  • Inert

Typical Applications

Refractories, PVC flooring, oilwell cements, brake linings, Phenolics, Epoxies, Cast Polyesters, synthetic marbles, syntactic foams, BMC, SMC and FRP. Low density cements, shotcrete and gypsum board joint compounds. Automotive sound-dampening sheets.

Advantages

Reduced weight, increased filler loadings, better flow characteristics, less shrinkage and warping. Improved physical properties in moldings, castings and laminates, reduced water absorption, improved flame retardance, improved chemical resistance.
