PropertiesWhite or pale yellow powder, low  toxicity. Soluble in organic solvent such as benzene, ethanol, acetone, etc. Insoluble in water. It is considered to be a potential skin sensitizer.
Uses 

 It is an  effective chemical peptizer for NR and SBR. It is specially suitable for mixing  at high temperature over 120°C.It can reduce the milling time greatly and  thereby can save the power consumption, and it has little effect on the aging  properties of rubber products While improving  the process ability. It  isn't blooming from rubber. It disperses readily in rubber and should be added  at the beginning of the mixing cycle, using either internal mixers or open  mills.
