Project cooperation leads to innovation in polyolefin stabilisation.
In response to market need for and efficient solutions, Sumitomo Chemicals have developed a unique range of plastics stabilisers.
Sometimes more advanced polymer polymerization technology is required for a proper response to market needs.
For use in food wrappings or electronic components, it is more necessary than ever that the additives, their decomposition products or polymers that have low molecular weight are not transferred to the food or the surface of the product, so that contamination of the product and/or the mold due to bleed-out will not occur.
It is common to use a combination of phenolic antioxidant and a phosphoric antioxidant as processing stabilizers.
The focus of Sumitomo’s development was to develop a more modern and efficient system which also could reduce the total amount used with better purity for the given application. The result was their G-series of SUMILIZER®additives and all was tested by Norner.
Norner has made a thorough work on assessing the efficiency and performance of the SUMILIZER® GP in both LLDPE and PP materials. A unique feature is that it contains both a phenolic and a phosphoric antioxidant in one chemical molecule.
Because of this dual functionality the SUMILIZER® GP is capable of neutralising all different radical reactions in the polymer matrix.
