Features and benefits

• Non-crystalline silica - safe for human
  Superior in hardness to other silica abrasive - Wear resistant
• Porous - absorbent and breathable
• Very light but large in capacity - Good as filler
  
• Silica is the principal component - Fireproof and heat- insulating effect
• Inorganic substance - No resolution, no combustion, no corrosion and chemical stability
• Two series are available. They are supplied after precise pulverizing, grading and severe quality control.
  LHM series: Low Heavy Mineral with heavy mineral of 0.1% or less
  NCS series: particularly fine Non-Crystalline-Silica with 3-15 micron size
• Wide range of particle size, nearly 50 variations from 3μm to 4 mm
• Custom-made particle distribution is available.
