White Solid Silane with Silica Crosile® 69S

Crosile® 69s 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.

Suitable polymers include NR, IP, SBR, BR, NBR, EPDM, etc.
