Silica product for use in elastomers |
摘要 |
A precipitated amorphous silica product particularly useful as a highly dispersible filler to elastomeric compounds, especially rubber passenger tire tread formulations. The invention has a CTAB specific surface area of about 10 m2/g to less than 140 m2/g; a multi-point BET surface area of about 50-261 m2/g; a 5% pH value of about 5.0-8.5; a DBP oil absorption of about 160-310 cm3/100 g; a linseed oil absorption of about 150-300 cm3/100 g; a projected surface area of no greater than about 4000 nm2; and a pore volume ratio of pores ranging from 175 to 275 ANGSTROM in diameter to all pores less than 400 ANGSTROM in diameter of about 10% to less than 50%.
