X 266-S® is a blend of the bifunctional, sulfur-containing organosilane Si 266® and an N 330 type carbon black in the ratio 1:1 by weight. The product is applied in the rubber industry in combination with white fillers containing silanol groups.
Typical Applications
Low rolling resistant tires
Benefits at a glance
X 266-S® was developed for customers who prefer to handle Si 266® in a solid version. The Si 266® in the X 266-S® reacts with hydroxyl groups of white fillers during mixing and with the polymer during vulcanization under formation of covalent chemical bonds. X 266-S® imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance, and optimized dynamic properties.
Compared to X 50-S®, a blend with polysulfidic organosilane, X 266-S® has a higher temperature stability and therefore allows higher mixing temperatures.

Further Information
Storage:
The storage stability only applies to material stored under appropriate conditions:
- original un-opened packaging
- stored dry and frost-free
- protected from direct sunlight
Aqueous acids and bases accelerate the transformation of organosilanes to polymeric siloxanes. Therefore, organosilanes should be stored in a dry place, away from acids and bases.
Opened bags should be used within a brief period of time.
