Silane Coupling Agents

All sulphur functional silanes from JHSi are supplied in liquid form. For easier handling we offer dry blends of liquid silanes with carbon black.

Functional organosilanes are used as coupling agents in the rubber industry in a variety of applications. They improve the physical properties of the finished product and also simplify the processing of rubber compounds during mixing and extrusion.

JH-S69

Bis[3-(triethoxysilyl)proplyl]tetrasulfide

40372-72-3

Used in rubber compounding providing coupling of non-black pigments to the polymer backbone to ensure improved abrasion resistance, higher compound modulus, lower hystersis, improved compression set. Improves rolling resistance in tyre tread compounds. In addition to being used in the tyre compounds also used in Industrial Rubber Products and rubber shoe soling.
