This product is an organosilicon solution containing sulfur and oxygen heteroatoms in its cyclic structure. 

The solution is the mixture of : 2,2-Dimethyl-1,4,2-oxathiasilinan-6-one (CAS: 18163-71-8) &  2,2‐Di(tetrahydrofuryl)propane (CAS : 89686-69-1) & other solvents.

 It is a polar modifier, also called randomizer, used for the 

production of solution Styrene Butadiene rubber (sSBR) to 

control the microstructure of the polymer, providing high vinyl content

 and even distribution of styrene. 

It is a liquid chemical used primarily as a building block for organic synthesis

 and pharmaceutical research.

It demonstrates the ability to engineer SSBR compounds that 

meet the conflicting demands of low rolling resistance (energy saving) 

and high wet traction (safety), which are critical for modern high-performance tires.
