Crosile®69s it is a mixture of Crosile®69s silane coupling agent and precipitated silica with the same function as Crosile®69s but easier to operate.
It can improve the physical and mechanical properties of rubber and greatly strengthen tensile strenth, antitearing strenth, abrasion resistance, reduce the permanent deformation and viscosity of gross rubber, improve process property.
The suitable polymer include NR, IP, SBR, BR, NBR, EPDM, etc.

Application
1. Crosile®69S is a kind of multifunctional silane coupling agent that has been used successfully in the rubber industry.
2. It is used to improve physical and mechanical properties of vulcanizates.
3. It is able to markedly improve tensile strength, tearing strength and abrasive resistance and reduce compression set of vulcanizates.
4. In addition, it can reduce the viscosity and improve the processability of rubber products.
5. Crosile®69S is especially suitable to improve the reinforcing properties of fillers that contain hydroxyl groups in all unsaturated polymers having double bonds or their blends.
