Celogen OT p,p’-Oxybis(benzenesulfonylhydrazide) Crompton Surfactants Rubber - Elastomer (Chloroprene, Butyl …) Ethylene co-terpolymers - solid (EVA, EMA...) SEALANT >> Foam p,p’-oxybis(benzenesulfonylhydrazide) Chemical Foaming Agents CELOGEN ® OT for Plastics LOW-TEMPERATURE CHEMICAL FOAMING AGENT CELOGEN OT is a low-temperature foaming agent suitable for operating temperatures of 300-350°F (149- 177°C). It is recommended for rubber, LDPE, EVA, and soft vinyl compounds. It generates a polymeric, non-polar residue that does not interfere with electrical properties in wire insulation applications. Process temperatures should not exceed 350°F (177°C) when using CELOGEN OT. Materials such as triethanolamine and urea are strong decomposition activators. Zinc oxide and similar materials provide moderate to weak activation. CELOGEN OT is oil-treated to reduce dustiness. It has three FDA sanctions for use in food-contact applications. Oil-treated p,p’-oxybis(benzenesulfonylhydrazide). Used as a low-temperature foaming agent for rubber, LDPE, EVA, and soft vinyl compounds. Provides polymeric, non-polar residue. Can be used in combination with traditional activators such as zinc oxide to provide moderate to weak activation.
