Adsorbent TOMITA-AD Series
Adsorbent TOMITA-AD Series
- Our adsorbents are chemically stable in both organic and aqueous solvents and have excellent stability against heat, oxygen, humidity, and light.
- The combination of acidic and basic points allows for a variety of applications.
- In addition, the spray-dried fine-grained product has spherical granularity and is size controlled, allowing for excellent flowability and filterability.
- The physical strength of the fine particles is also excellent, and they can be used stably throughout the adsorption treatment operation.
