Kemsylan S69

Bis[3-(triethoxysilyl)propyl]tetrasulfide
CAS #: 211519-85-6 

Features

Kemsylan S69 molecule contains sulfur atoms and silane groups. The sulfur atoms react with the sulfur in rubber during vulcanization to form a sulfur cross-linked network, while the silane groups react with the surface of inorganic fillers to form siloxane bonds, firmly bonding the rubber and filler together.

Applications

Kemsylan S69 is a high-performance rubber additive with a wide range of applications in the rubber industry. Its unique molecular structure and properties make it an excellent choice for enhancing the performance of rubber products.
