Static-free synthetic rubber

A process for producing static-free synthetic rubber includes mixing acrylonitrile-butadiene, Anti-static agent, Activated zinc oxide, Zinc stearate, HI-sil (EPDM), Plasticizer, and Stearic Acid prior to a kneading process at 140 degrees Celsius for 8 to 12 minutes. (DCP) Peroxides and Blowing agent...

More Information
Summary:A process for producing static-free synthetic rubber includes mixing acrylonitrile-butadiene, Anti-static agent, Activated zinc oxide, Zinc stearate, HI-sil (EPDM), Plasticizer, and Stearic Acid prior to a kneading process at 140 degrees Celsius for 8 to 12 minutes. (DCP) Peroxides and Blowing agents are added to the kneeing mixture two minutes before the end of the kneeding process. After the kneeding process, the resultant mixture is fed through rollers to form a sheet of the synthetic rubber. The sheet is then cut into appropriately-sized pieces and put into a mold, where the pieces are subjected to high pressure and a temperature of 160 degrees Celsius. The pieces are then left to cool, and then be used for articles such as static-free footwear.
