Famous JooSorb AST-01 Manufacturer, Product

JooSorb AST-01 is a high surface specific area promoted spherical activated alumina adsorbent provides high water and TBC adsorption capacity.

TBC (tertiary butyl catechol) is commonly used as a polymerization inhibitor added to monomers to inhibit polymerization during storage and transportation. The removal of inhibitors is necessary prior to polymerization processes, as is the case of synthetic rubber production.

Frequently Asked Questions (FAQ)

What is the primary function of AST-01?

AST-01 is specifically designed for the highly efficient removal of water and tertiary butyl catechol (TBC) from monomers, including butadiene, isoprene, and styrene.

Why is it necessary to remove TBC from monomers?

TBC acts as a polymerization inhibitor during monomer storage and transport. It must be removed before the polymerization process begins (such as in synthetic rubber production) to ensure proper reaction.

What size options are available for AST-01?

AST-01 is available in spherical form with two nominal sizes: 1.5-3.0 mm (equivalent to 1/16”) and 2.0-5.0 mm (equivalent to 1/8”).

What is the expected shelf lifetime of this adsorbent?

Under proper storage conditions, AST-01 activated alumina adsorbent has a shelf lifetime of over 5 years.

What are the bulk density and surface area specifications?

AST-01 has a bulk density of 0.7-0.8 g/cm³. The specific surface area is promoted to >320 ㎡/g for the 1.5-3.0 mm size and >300 ㎡/g for the 2.0-5.0 mm size.

How is the product packaged for delivery?

It is packaged in industrial-grade configurations, either in 800 kg big bags or 150 kg steel drums, ensuring safe transport and storage.
