Initiators for High Polymers Organic peroxides are also important materials Safety, Research & Development in pharmaceutical and fine chemical synthesis We have a long history in the organic peroxides arena, starting with or as active pharmaceutical ingredient Thorough understanding and knowledge of free radical chemistry and dibenzoyl peroxide for the bleaching of flour in the early 1920’s We are able to supply a comprehensive range peroxide production technology is at the basis of the development of initiators to meet all requirements with This Akzo Nobel invention was the beginning of the production and respect to area of application, polymerization of new, more efficient and safer products serving customer needs temperature, rate of radical formation and application of organic peroxides worldwide Since then, many new storage facilities With almost a century of experience we are your reliable and organic peroxides have been added to our product line, with the Listed are the highest concentrations of innovative partner for the supply of organic peroxides formulations for each phlegmatizer growth of plastics in everyday life We invite you to visit us at www.akzonobel- The Continuous Initiator Dosing (CID) venture, polymerchemicals.com for complete product which is a process improvement technology listings Formulations with phlegmatizers or for the manufacture of PVC, is a good concentrations other than those indicated as example of our efforts in the field of R&D well as unique custom blends of various peroxides can be made available with due Technical support and product development observance of safety characteristics and the are mainly provided from laboratories in Today, we are the world’s largest producer appropriate environmental and transportation Deventer - the Netherlands, Pasadena - Tx of initiators for free radical polymerization regulations Please consult your Akzo Nobel USA, Los Reyes - Mexico and Tianjin - China of various monomers The main area of account manager for your specific need The first is the site of the company’s fundamental initiator R&D In each continent application is the manufacture of high polymers such as acrylics, low density We operate organic peroxide manufacturing we have a team of Technical Development polyethylene (LDPE), polyvinyl chloride (PVC), sites and distribution centers all around the Managers who are the liaison between the controlled-rheology polypropylene (CR-PP) world including joint ventures Ankorit - market and R&D and facilitate the technology and styrenics The largest part of our Russia, Kayaku Akzo Corporation - Japan, transfer to and from our customers initiators program consists of organic and in China Tianjin Akzo Nobel Peroxides, peroxides (O-O initiators) which can be Keum Jung Akzo Nobel Peroxides and Akzo Our success in safely handling organic divided into classes such as peroxyesters, Nobel Crosslinking Peroxides peroxides is due to our long-term peroxy(di)carbonates, diacyl peroxides, commitment to safety dialkyl peroxides, peroxyketals and All production sites are certified with ISO hydroperoxides In addition we supply azo 9001 and ISO 14001 in order to ensure the The Safety Research laboratory in Deventer (N-N) initiators and carbon (C-C) initiators highest product quality and strictest participates in R&D by the development of compliance with environmental regulations safe products and processes Investigations are performed with the objective to assure a Akzo Nobel is a Responsible Care® company high level of safety in manufacturing, handling and transport of our products 6 Storage & Safety Half-life Storage temperatures UN Numbers The most important characteristic of a polymerization initiator is its rate of decomposition The Ts max is the recommended maximum All products accepted for transport are assigned to generic entry numbers according expressed by its half-life (t1/2) For this reason, the initiators in this product catalog are storage temperature at which the product is to classification principles as described in the recommendations by the United Nations arranged in descending order of activity, based on the 1.0 hour half-life temperature stable and quality loss will be minimal Committee of Experts on the Transport of Dangerous Goods An explanation of all The half-life is the time required to reduce the original initiator content at a given temperature A minimum storage temperature (Ts min.) is relevant UN numbers is given in table by 50% With the exception of hydroperoxides, the half-life is determined by differential given if phase separation, crystallization or scanning calorimetry-thermal activity monitoring (DSC-TAM) of a dilute solution of the solidification of the product is known to initiator in monochlorobenzene Kinetic data of the decomposition of hydroperoxides in occur below the temperature indicated For monochlorobenzene are determined titrimetrically safety reasons it is also recommended to store the product above the Ts The tables in this catalog list the temperatures at which the half-lives are 0.1 hour, indicated
