Properties: Low toxicity,insoluble in water,soluble in organic solvent such as benzene,ethanol, etc.Contact with skin will cause dermatitis.
Applications: It is an effective chemical peptizer for NR and SBR.It is specially suitable for mixing at high temperature over 120℃ .It can reduce the milling time greatly and thereby can save the powder consumption,and it has little effect on the aging properties of the rubber products while improving the processability.It isn’t bloming from rubber.Peptizer P-22 disperes redily in rubber abd should be added at the beginning of the mixing cycle,using either internal mixers or open mills.Recommended dosage levels in NR are 0.05-0.5%,and in SBR are 0.5-3.0%。
Storage: Stored closely in a cool,dry,well-ventilated area.Avoid exposure to direct sunlight
Package: In 25kg paper bags with prastic inner
