Expanded Perlite 50–70 mesh

From Harbour Refractory — reference entry

Expanded perlite 50–70 mesh is a finer grade of perlite used for insulation and lightweight composites requiring smooth surfaces.

Description

The controlled grain size provides improved packing and reduced voids in formulated products. Used where fine texture and low thermal conductivity are desired.

Applications

  • Insulating coatings and fillers
  • Fine lightweight concretes and boards
  • Thermal insulation layers in equipment linings

Packaging

  • Supplied in moisture-protected bags on pallets
  • Labels indicate product grade and size
  • Handle to prevent crushing during handling

Storage

  • Store dry, covered, and ventilated
  • Avoid stacking heavy loads on top
  • Use FIFO to ensure consistent physical properties
