Omnistab UV 360

Omnistab UV 360 is a chemically phenol, 2, 2-methylene-bis (6-(2H-benzotriazol-2-yl)-4-(1, 1, 3, 3-tetramethylbutyl)) grade. Acts as an UV absorber. It is a very low volatile product of hydroxyphenyl benzotriazole class, imparting outstanding light stability to a variety of polymers. Particularly suitable for processing and aging conditions where high loads and good compatibility are required. Helps to achieve high UV screen performance and minimizes sublimation through vents as well as prevention of deposits on molds, chill rolls or calibrators.

Also suitable for complex moldings, fibers, sheets, twin wall sheets, thin films and laminated or co-extruded semi-finished articles. Compatible with acrylic resins, polyalkylene terephthalates, polycarbonates, modified polyphenylene ether or sulfide compounds, polyamides, polyacetals, styrenics, elastomers and various high performance plastics. Omnistab UV 360 (0.2-10% by weight) can be readily incorporated in the polymer by using conventional techniques such as powder, solution, or melt blending such as extrusion compounding.

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.

Deltachem is the partner of Choice for Partners in Chemicals.

Besides being responsible for sourcing new products, supplychain and quality controle Deltachem is also managing the production facilities and handles the technical support.
