The rocky road to perfect silica compounding

摘要

1. Processing advantages1.1 High uptake of mixing energy, low slip effect1.2 Low Mooney viscosity following mixing1.3 Very stable viscosity with time after mixing1.4 Excellent extrusion performance1.4.1 High flow rates1.4.2 Low extruder pressures1.4.3 Good surface and edge finish to extrudate1.5 Long scorch time.2. Cured Properties2.1 Lower change in modulus and hardness2.2 More stable compounds than with 1st or 2nd Gen, products (high modulus, high tensile strength)3. Dynamic properties3.1 Lower heat build up on flexing3.2 Positive influence on tyre dynamic property3.2.1 Tan δ at high temperature is improved.
