40372-72-3 Crosile 69 Sulfur Silane Coupling Agent Provide Silica Treatment For Shoe Sole
Type :Sulfur Silane Coupling Agent Crosile - 69
CAS No. : 40372-72-3
Chemical Name: Bis [3-(triethoxysilyl) propyl] tetrasulfide
Formula: (C2H5O)3SiCH2CH2CH2-S4-CH2CH2CH2Si(OC2H5)3
Physical Properties
Silane Coupling Agent Crosile - 69 is a pale yellow clear liquid with light odor. It can provide a stable bond by reducing the interfacial tension between the fibrous of particulate inorganic component and the organic matrix polymer in reinforced and filled plastics.

| Resiue On Ignition(800±25℃) | 11.3±1.0% |
Application
Silane Coupling Agent Crosile - 69, when it apply in shoe soles, It can provide coupling of silica to polymer backbone.
It can significantly improved abrasion resistance and anti-pressure properties of rubber to reduce the viscosity of the adhesive to save energy in this process.
It has longer flexural life.
It can apply as a white filler.
