Transparent Silica Gel Desiccant

Detailed Product Description

Silica Gel Desiccant
Principle
They appear as transparent, glassy,smooth and globose granules. They are nontoxic, milk-toast, harmless and litmusless, and they are the only kind of desiccants with the function of indicating temperature. They belong to chemical products, absorb water physically, nondegradable. The content of heavy metal is lower than the standard of ROHS(EU) and GP(Sony).
Applications
Be widely applied for dehumidification of the computer equipments, sophisticated machinery, optacle glass instruments, test for semiconductor products encapsulation and food products.
Creteria
Meets international standard specifications such as MIL-D-3464E(US), JIS Z 0701 (Japan) and DIN 55473 (Germany).
