Evonik Ultrasil 7000 GR is original German highly dispersible granulated precipitated silica, specially developed for low-rolling-resistance green tire treads. It features high reinforcement, easy dispersion, dust-free, and greatly improves abrasion, wet grip and rolling resistance.
Ultra-high dispersion – fast mixing, uniform dispersion, no agglomerates
High reinforcement – greatly improves tensile, tear, abrasion and dynamic properties
Granulated & dust-free – smooth feeding, eco-friendly for automatic lines
Excellent tire performance – balanced abrasion, wet grip and rolling resistance
Stable processing – good compatibility with silane, stable vulcanization
Green tire tread – passenger car tires, winter tires, better wet grip & rolling resistance
Tire sidewall/bead – higher strength, flex and aging resistance
High-performance rubber goods – dampers, seals, hoses, belts
Rubber shoe soles – improved abrasion, resilience and appearance
EPDM/SBR/NR compounds – efficient reinforcement for general & special rubber
