Product Code: ACH Si-SUL-69

Chemical Name: Bis[3-(triethoxysilyl)propyl]tetrasulfide

CAS No.: 40372-72-3 

ACH Si-SUL-69 is an organo-silane coupling agent that contains sulfur. It is used primarily in making tires and rubber products due to its ability to improve tensile strength, moduli, abrasion resistance and other properties. ACH Si-SUL-69 reacts with hydroxyl fillers during mixing and with polymer during vulcanization. This product typically replaces Si-69® and SilquestTM A-1289.
