Small Particle High Density Waterproof Perlite Powder

Perlite Introduction Expanded perlite powder is a white or light-colored superior thermal made through smashing acid volcano glass lava, screening to a certain granularity, preheating again, and sintering under high temperature of 1400C. And it can be compounded with different adhesive into hydrophobic perlite insulation board, perlite sound absorption board, partition board, fire proof board, etc.ITEMPERLITEGranularity(mm)0.1-1.5Volume Weight      (Kg/m³)200-300Heat Conductivity      (W/m.k)0.047-0.054Fire-resistant limit(hours)1-2Bending strength(Mpa)≥0.8Compressive strength(Mpa)0.35-0.8Pelletizing Ratio(%)70-90Closed Cell Ratio(%)≥95Moisture Absorption50-85Refractoriness1280-1360Service temperature-40~600℃Application1-3mm , 2-4mm expanded perlite powder usually be used as insulation material of building, the  perlite is a good material to build external thermal wall. 3-6mm, 4-8mm expanded perlite usually be used for horticultural using .
