TDS Silica gel Specification

Silica Gel is a high activated adsorpxion material, is widely used in desiccant and absorbent. It is a high-powered absorbent in every humid environment and is the only desiccant used in food and medicine by FDA.

Silica Gel Desiccant—Index of correlation

Quality correlation:

It comes up to the GB10455-89(also according to agreement with the customer).

Adsorpxion of the unit:

Adsorbing capacity RH=20% ≥10%

Adsorbing capacity RH=40% ≥ 20%

Theory of Silica Gel

   Transparent，glassiness，smooth global, nonpoisonous and tasteless, neutral and non-corrosiveness，only one desiccant which has indicator，it is chemical product，physical wicking and environmental. Non-degradable, the extractable metal content is lower than ROHS standard and GP standard.

Scope of application

   The objective service in: sophisticated electronic equipment，Hardware, machinery, Wood ware, clothing and shoe industry, medicine, food, container sea transportation and so on.

Standard:

    In line with the national technical standards for Board inspection requirements Such as MIL-D-3464E, JIS Z 0701, DIN 55473
