Features

Nano-silica particles according to their structure are divided into two types: P-type (Porous particles ) and S-type (Spherical particles). P-type nano-silica surface contains a number of nano-porous with the pore rate of 0.611ml /g; therefore, P-type has much larger SSA comparing to S-type (See US3440). US3436 is S-type and its SSA is ~170-200m2/g. Further more, P-type ultraviolet reflectivity is >85% , S-type: >75%.
