And chemical composition:
Double (for 3-ethyl trimethylsilyl-propyl) four sulfide (Si-69) dispersed in polymer carrier.
Second, the physical properties:
Appearance: yellow granules
Density: 1.45g/cm ³
Third, product effectiveness:
1, modification of silica, thereby improving filling many properties of silica gel. Chemical bonding andhigh dispersion of filler, and rubber bond, gives it excellent physical and mechanical properties.
Level 2, improve, and long flat period, preventing anti-reversion.
3, Si-69 than the liquid, can be dispersed quickly, shortening mixing time, increase productivity, andreduce energy consumption.
4, Si-69 than the liquid, can guarantee the uniform of white carbon black in the mixing coupling, improvingthe coupling efficiency of silica.
5, Si-69 than the liquid, silica and rubber crosslinked optimization, almost 100% of silane coupling agent in reaction, thereby reducing the dose, and no residual adverse effects of coupling agent in rubber.
6, not a liquid, Si-69, hydrolysis of water easily, so the moisture stability.
Widely used in tires, rubber products, and wear-resistant soles for reinforcing agent agent mixing added.
Five, the dosage:
Recommended dosage is 1-4. Replaced Si-69 of pure liquid, we recommend that you follow the dosage of pureliquid, depending on the effect of discretionary change.
Six packing: 20Kg/barrels.
Seven, shelf life: 12 months.
