It is an effective chemical peptizer for NR and SBR. It is especially suitable for high temperature mixing above 120℃, which can greatly reduce the time of ball milling, thereby saving power consumption, having little effect on the aging performance of rubber products, and improving the processing capacity. It does not bloom from rubber. It is easily dispersed in the rubber and should be added at the beginning of the mixing cycle using an internal mixer or open mixer.
