Product Description
Speification:
1.silica gel packets 2.china silica gel 2.High Absorptivity Dryer 3.Non-toxic and safe
Introduction
Silica Gel Desiccant is a high-activity sorbent,which is the result through chemical reaction between sodium silicate and sulfuric acid and then ageing and sour bathing.Silica-gel is an amorphous substance.Its molecular formula is mSiO&sub2;H&sub2;O.
It features a stable chemical property and never reacts with any substance except the alkali and hydrofluoric acid.Because of chemical composition and physical structure of silica-gel,it possesses many advantages as desiccant.For example,high absorption capacity and non-shape changing.It is a non-toxic,odorless and green-environmental material.
Features:
1) Pack Weight: (bag) 1g 2g 3g 5g 10g 20g 30g 50g 100g 200g 500g 1000g or customer-specified
2) Packing materials:composite paper, tyvek paper,non-woven paper,cotton paper, mesh paper, Aihua paper,Aihua,CT Cloth,etc
3) Printing:printings in English,Japanese, German and Spanish or customer required.
4) External packaging: plastic bags or iron buckets in corrugated cartons
5) DMF&CoCl2 Free . SGS,MSDS Approval.
Applications: Used for absorption for moisture in order to keep proper humidity.It is used widely in the storage of garments,bags,food,medicines,toys,woodworks,instruments,meters,electrical appliances and computers.
