Product Information

Chemical Name：Bis-(γ-Tri ethoxy silyl propyl)-tetrasulfide

Product Code：LT-1289

Molecular Formula：C₁₈H₄₂O₆S₄Si2

Molecular Weight：538.95

CAS NO.：40372-72-3

Properties and Reactivity

LT-1289 is a bifunctional sulfur-containing organosilane, which can be used in the combination of rubber and white base material containing silanol groups.

LT-1289 reacts with the white base material containing silanol groups and the polymer to form covalent chemical bonds when mixed.  This gives the product greater tensile strength, stronger moldability, reduced compression deformation, increased wear resistance, and enhanced dynamic characteristics.

Technical Data

Note: the above data is for reference only, cannot be as a technical specification. 

Application

LT-1289 its white filler containing silanol group and its best technical performance are necessary conditions for its application in various fields of the rubber industry.  It is widely used in radial tire and rubber tire tread, body, outer wall, solid rubber tire roller and other rubber products.

Such as low rolling resistance tires, mechanical rubber products and soles.

This product is also suitable for dry mixing with carbon black in a 1:1 ratio, code X50-S.
