Polymer bound Rubber Coupling Agent Si69-50GE
CAS 211519-85-6 Rubber Coupling Agent Si69
Rubber additives for tires, shoes soles, belt, conveyor Si69-50
Rubber bonding agent Silane masterbatch
Properties
Si69 bonding with highly dispersed filler such as silica, on the other side bonding with rubber, it has excellent properties of dynamic and static after vulcanization. Si69 significantly reduce the mixing viscosity and improve the abrasive resistance and modulus of rubber.
Dosage
Mixing with reinforcing agent,5-20%of silica,1.0-2.0%of clay and mica.
Application
Used in tires,shoe and drum,rubber hose,belt,V belt,etc ;In tres and other rubber products,used as wear-resisting agent and reinforcing agent

Product advantages
It can build a bonding bridge between silica and rubber, significantly reducing the Mooney viscosity of the rubber compound, improving the dispersion of fillers; reducing the rolling resistance of tires, enhancing the wear resistance and tear resistance of the products; the granular form of material addition is simple and the measurement is precise, avoiding waste and volatilization of liquid coupling agents; the processing stability is good, it is not prone to premature reaction, and the safety of carbonization is higher; it has strong compatibility with various rubbers and accelerators, and can directly replace liquid SI69 without significant adjustment of the original process.
FAQ
Q: What are the differences between SI69-50 and liquid SI69?
A: The masterbatch version is safer, more convenient to use, has more accurate measurement, and lower loss. It is suitable for automated production lines.
Q: What is the normal addition amount?
A: Generally, it is 4% - 6% of the amount of silica. It can be adjusted slightly according to the formula.
Q: Storage precautions?
A: Store in a sealed, cool, dry place, protected from light and moisture. Avoid high temperatures as they may cause component decomposition.
