• Antistats
• Blowing Agents--Chemical Type

  Manufactures Celogen azodicarbonamide foaming agents used to foam plastics to impart a cellular structure into the resin via processing techniques such as injection molding, extrusion or PVC expanded materials. Main products include Celogen AZ types and OT. Products may be used to reduce weight, improve softness and resilience, simulate the appearance and behavior of wood, and for cosmetic surface effects. Products cover a process temperature range of 284 F and higher.

  Also offers a range of Celogen modified azos such as Celogen FF that provide clean, trouble-free products in extrusion, injection molding and calendering. Products contribute to uniform cell formation and smooth surfaces. FF grades do not generate foaming agent plateout. Celogen 125FF is a 3-4 micron particle size most often used for thermoplastics processing in the 380-400 F temperature range. Celogen 60/14FF (9.5-13 microns) is suitable when greater thermal stability and a slower rate of decomposition are desirable. It is especially suited in the molding of PP, HDPE, ABS and PPO materials.

  Celogen 780 modified azo is for use in both plastic and rubber applications where a low decomposition temperature and fast rate of gas release are desirable. Plastics that can be foamed with this include standard and metallocene polyolefins, various thermoplastic elastomers, and soft and low-melting PVC formulations.

  Company also offers Expandex 5-PT (5-phenyltetrazole), suitable for foaming higher temperature polymers such as PC, nylon 6/6, PBT and PET. The inert decomposition products from Expandex 5-PT help to avoid chemical degradation and molecular weight loss with hydrolysable polymers such as PC and thermoplastic polyesters.
