Nouryon Polymer Modification Additives

Nouryon is a global leader in the industry of free radical initiators for the production of thermoplastic polymers such as PVC, LDPE, acrylates and styrene. Our organic peroxides are also used to modify thermoplastics by reactive extrusion. The choice of peroxide depends on the type of polymer, the required reaction and the extrusion temperature. Controlled Rheology PP (CR-PP) Polypropylene produced with Ziegler-Natta catalysts typically has a wide molecular weight (MWD) distribution. This results in a highly elastic melt that is not easily processed on high speed machines. This problem can be effectively solved by adding special organic peroxides to the extruder to allow controlled degradation of the polymer. There are

Nouryon Superconducting Carbon Black Ketjenblack

Nouryon (Nouryon) is the market leader in conductive carbon blacks. Carbon black is often used in polymers as a conductive medium. Carbon black is distributed throughout the polymer's structure, thus providing a balanced conductive effect and enabling the polymer to achieve a surface volume resistance of up to 1 ohm.cm. Unlike antistatic agents, this conductive effect is not dependent on mobility or humidity. Our Armostat® range of antistatic agents provides excellent antistatic effects with surface resistances as low as 10¹⁰ ohm. For lower resistances, Ketjenblack® EC conductive carbon blacks are preferred. Our Ketjenblack® EC super

Organic peroxides in rubber cross-linking: types, characteristics and limitations

Organic peroxides have a wide range of applications as crosslinkers in rubber processing. However, different types of organic peroxides have different characteristics and limitations in rubber crosslinking. Among them, the half-life and the type of free radicals generated by decomposition are important factors affecting the suitability of organic peroxides as cross-linking agents. For organic peroxides, their half-life should be neither too short nor too long. If the half-life is too short, there will be burning problems in the mixing stage; while the half-life is too long, it will lead to too high a vulcanization temperature or too long a vulcanization time. Therefore, when choosing organic peroxides as crosslinking agents, it is necessary to determine the range of its half-life according to the specific application. In addition, in the organic peroxide
