Flow-Treated Celogen AZ-2990 Azodicarbonamide Crompton Surfactants Surfactants >> Amides Rubber - Elastomer (Chloroprene, Butyl …) Polyolefins (PE, PP…) SEALANT >> Pre-formed tape / Gasket SEALANT >> Plastisol SEALANT >> Foam Chemical Foaming Agents CELOGEN ® AZ for Plastics Azodicarbonamide CELOGEN AZ is the most widely used chemical foaming agent for producing many types of polymeric closed-cell foam. It is also used as a nucleator in some physical foaming processes. Polymers foamed with azodicarbonamide include rubber, polyolefins, vinyls, styrenics, thermoplastic elastomers of all types, and engineering plastics such as polyphenylene oxide. CELOGEN AZ is the major component in a variety of modified azodicarbonamide blends developed to meet special requirements in foam processes. Modified azodicarbonamides include blends with activators to reduce decomposition temperature, flow-treated types to improve flowability, liquid dispersions for vinyl plastisols, and nonplateout grades that reduce foaming agent plateout (cyanuric acid). A number of particle size grades of CELOGEN AZ are also available. In polymer systems containing activators, particle size may be used to adjust the rate of decomposition when needed, especially in systems where crosslinking or fusion take place. Typical activators used to reduce decomposition temperature include zinc oxide, zinc stearate, zinc octoate, urea, and vinyl stabilizers. The amount of activator required will vary depending on the reduction in temperature desired. Closures with Sealing Gaskets for Food Containers Flow-Treated CELOGEN  AZ for Plastics Azodicarbonamide with less than 2% inert flow conditioner Flow-Treated CELOGEN AZ grades were developed to reduce agglomeration during storage and improve dispersability and flow characteristics. These products may be used as direct replacements in the same applications where unmodified CELOGEN AZ grades are used with no loss of efficiency. The flow-treated products have the same properties and characteristics of unmodified CELOGEN AZ. It is possible to directly disperse Flow-Treated CELOGEN AZ into vinyl plastisols without making a plasticizer/foaming agent dispersion. The improved flowability of these products allows their use in automated metering and blending systems. In cases where a liquid foaming agent dispersion must be prepared, these products exhibit less settling and separation compared to unmodified CELOGEN AZ. These products are available in three different particle size grades. Azodicarbonamide with inert flow conditioner. Used as a foaming agent for producing many types of polymeric closed-cell foam and as a nucleator in some physical foaming processes. Offers compatibility with rubber, polyolefins, vinyls, styrenics, thermoplastic elastomers of all types, and engineering plastics such as polyphenylene oxide. Can be used in combination with activators such as zinc oxide, zinc stearate, zinc octoate, urea, and vinyl stabilizers to reduce decomposition temperature. Reduces agglomeration during storage. Improves dispersability and flow characteristics. Can be directly dispersed into vinyl plastisols without making a plasticizer/foaming agent dispersion. Applications : closures with sealing gaskets for food containers.
