Omnistab AN 3114

Omnistab AN 3114 is a sterically hindered phenolic antioxidant for processing and long-term thermal stabilization. It contains 1,3,5-tris(3,5-di-tert-butyl-4-hydroxybenzyl)-1,3,5-triazine-2,4,6(1H,3H,5H)-trione. It is a highly effective, non-discoloring stabilizer. Omnistab AN 3114 has low volatility and high resistance to extraction. It is odorless and stable to light. It protects the substrates against thermo-oxidative degradation. It is compatible with polyethylene, polypropylene, polybutene, linear polyestser, PVC, polyamides, polyurethanes, styrene homo- and copolymers, elastomers such as SBS, EPR, EPDM and other synthetic rubbers. Used in organic substrates such as polymers, synthetic fibers and elastomers. Its recommended addition level is 0.05-0.3%.

In 2007 we decided to start ICG Specialty Chemicals selling specialty chemicals and additives under the tradename Omnistab.



Partners in Chemicals expanded its business in Middle East by setting up a branch office in Dubai in 2014.

Our Dubai office gives direct access to the Middle East and Africa. Having warehousing facility in the Dubai Free Zone makes it much easier to import, stock and re-export material to different destinations around the globe.




To serve the American market we have set up our Chicago branch office in 2009.



Deltachem (Qingdao) Co. Ltd. has been established in 2012 but general manager Mr. Mike Zou is already since 2007 a business partner for the Omnistab range.
