Hi-Sil™ EZ

additif salt : Na2SO4. Easy dispersing for dynamic rubber applications. Through global manufacturing facilities, PPG Industries markets a full line of Hi-Sil® silicas designed for use in tire applications. Hi-Sil® precipitated silicas add improved performance and increased structural integrity to tires for every type of vehicle, both on and off the road. Used to alter the dynamic properties of the tread compound, usually in combination with silane coupling agents, to promote adhesion to brass-coated wire, alone or as part of the HRH or an alternate bonding system ,to promote adhesion to fabric cord, alone or as part of the HRH or an alternative bonding system, to alter stiffness in the bead area, to reduce the tendency for "chunk out" of off-road tire treads by improving compound tear resistance.
