Milliken Chemicals, a well known supplier of sorbitol based clarifiers, has introduced a new type of nucleating agent HDN-68 that produces nuclear density of 3 x 1011 compared to the next highest density of 4 x 1010. HDN-68 also shows first crystallization temperature of 130°C almost 28°C increase from the control resin of PP impact copolymer. HDN-68 apparently belongs to a new type chemistry. This new type of nucleating agent will be introduced early next year. Milliken Chemical claims that HDN-68 unlike the traditional nucleating agents like Na-benzoate etc could be used with sorbitol based clarifiers very effectively and reduces haze significantly. HDN-68 has shown better preformance in PP compared to other polymers. Infact, initially HDN-68 is being developed for automotive applications of PP like bumpers.
