Silicagel

Product explanation

Spherical Silicagel / amorphous physical adsorption desiccating agent / chief ingredient for the adsorption desiccating agent: / JIS, Z, 0701 certification / DMF 14359 registration that can choose weight suitable for the / use where blue gel plays a role as the indicator in SiO2 / MIX-type

Use

・It is a bag filling desiccating agent for medicine, meal grades.
・I am used as a desiccating agent for the export packing.
・It is available as dried flower business for the closet for the kimono for the piano.

Essence

I say a desiccating agent, and is a thing to imagine not a Silicagel entering the cakes at the very beginning? We have been sending a high-quality Silicagel product to a customer for many years.

Characteristic

  • It is the physical adsorption by the capillary phenomenon, and size and a shape do not have the change even if I adsorb it. Of course it is corrosive, and there are no deliquescence characteristics.
  • I can judge the moisture absorption situation from the blue gel for the indicator.
  • It is stable chemically and is superior in anti-medicine characteristics except extreme alkali, dorusan.
  • I can choose various weight and a packing form depending on a purpose.
  • It is JIS, Z, 0701 certification products.
  • It is a product registered with DMF 14359.

2) Ability for moisture absorption of the Tokai gel
I am superior in an adsorption power with the low humidity, and the type A Silicagel is used to keep sealing space low humidity.
The type B Silicagel is superior in an adsorption power at the high humidity. There is the water-releasing ability and is used as materials to moisture condition.

※In addition, I prepare various size, weight a lot.
I am doing the sale with the bulk, packing product, and the packing product has a film type, a nonwoven fabric type.
The serial packaging product (0.7G/1G/2G) has the film type, too.
 
In late years cobalt chloride is appointed to a carcinogen in EU, and the use is limited. Therefore I have the Silicagel using the non-cobalt indicator gel in order to meet the request of the customer exporting it for EU.
