High Dispersible silica 165 GR(Tire Grade)

High Dispersible silica 165 GRHDS 165GR is a mechanically compacted granulate use as a white reinforcing filler in the rubber industry.Specification:SiO2 - content (%) 93 minISO 3262-17Moisture - content (%) (determined 2 hrs/105ºC) 5.5 + /-1.5ISO 787-02Loss on Ignition (%) (determined 1hr/1000ºC) 4.0 +/- 1.0ISO 3262-11PH - value (5% aqueous suspension) 6.0 +/- 0.5ISO 787-09Specific Surface Area (m2/g) BET 170 +/- 10 ISO 5794-01Specific Surface Area (m2/g) CTAB 170 +/- 5ISO 5794-01Specific Gravity (g/cm3) 2.0 2.1ISO 787-10Tamped Density (g/m3) 300 +/- 40ISO 787-11Electrical Conductivity (μs/cm) 1300 maxApplication:HDS 165GR is an excellent dispersible and highly reinforcing silica which was especially developed for application in low rolling resistant passenger car tire tread compounds. It imparts to tread compounds high abrasion resistance combined with excellent rolling resistance and wet traction. Requirement for this is the combined use of HDS165GR and a bifunctional organosilane, either Si 69. Additionally the use of diethylene glycol, triethanolamine or other alkaline accelerators might be necessary in order to achieve optimum rubber-technical data.This product fulfills highest demands towards reinforcing filler. Packing and Storage: 20 or 10 Kgs in plastic bagStored in closed and dry premises protected against exposure to volatile substancesStorage life: one year in normal storing conditions.
