Microsilica Undensify 90%

Micro Silica In Fire Resistant Material:The traditional fire-resistant materials have many holes. If micro silica is filtered into the fire-resistant materials, it can enhance its volume and density , decrease its air vent rateMicro silica has strong activity and can form into colloid ion in water, and then buildup fluidity and improve moulding if it is added into some proper detraction ion.Micro silica can easily form into SI-OH group, and such it has stronger hydrophile performance and activity, buildups fire-resistant materials cohesion, improves high temperature and prolongs being of the fire resistant goods.
