X 50-S®

X 50-S® is a blend of the bifunctional, sulfur-containing organosilane Si 69® 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
- Mechanical rubber goods
- Shoe soles

Benefits at a glance

X 50-S® was developed for customers who prefer to handle Si 69® in a solid version. The Si 69® in the X 50-S® reacts with hydroxyl groups of white fillers during mixing and with the polymer during vulcanization under formation of chemical bonds. X 50-S® imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance, and optimized dynamic properties.
X 50-S® is used in a variety of rubber products where hydroxyl group containing white fillers are used and where optimum technical properties are required.

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.

Packaging:

25 kg bags on 1.000 kg plastic pallet
1.000 kg FIBC plastic pallet

Shelf life:

min. 12 months
