Carbon black/white carbon black

Dispersant HPP

A mixture of saturated fatty acid zinc salts

97-105

Light brown particles

It has a plastic decomposition effect on NR and IR, delaying coke burning and promoting vulcanization, which helps to remove the film of vulcanized products. Used for tires, various molded and extruded products, and hard rubber.

white carbon black

Dispersant HST

A mixture of polyol esters, zinc soap, and fillers

85-105

Light brown particles

Dispersants and lubricants for high filling diene synthetic rubber. Especially suitable for rubber materials containing high activity white carbon black, such as tire treads and industrial molded products.

Synthetic rubber/carbon black

Dispersant HT

A mixture of unsaturated fatty acid zinc salts

75-90

Light yellow to light brown particles

It has a plastic decomposition effect on NR and IR above 60 ℃. Delay coking and promote vulcanization. Suitable for use in low-temperature continuous mixing and open mill mixing. Used for various molded and extruded products, rubber foam products, and hard adhesives.

white carbon black

Dispersant HSK

A mixture of saturated fatty acid zinc salts and inorganic fillers

99-109

Light yellow to light brown particles

Commonly used dispersants and lubricants for rubber. Especially suitable for rubber materials containing high activity white carbon black, such as tire treads and industrial molded products.

Synthetic rubber/white carbon black dispersant HTX

Mixture of high molecular weight unsaturated zinc soap and filler

70-94

Light yellow to light brown particles

Processing aids for synthetic rubber have plasticizing effects on NR, IR, and their blends with other synthetic rubbers. Slow acting activator, suitable for use in low-temperature continuous mixing and open mill.

white carbon black

Dispersant H60

A mixture of fatty acid derivatives primarily composed of zinc soap

85-95

Light yellow particles

Processing aids for natural rubber and synthetic rubber. Improve the dispersibility of fillers, especially mineral fillers, and maintain the uniformity of each batch of rubber material.

Dispersant H60EF

A mixture of fatty acid derivatives primarily composed of zinc soap

90-100

Light yellow particles

Improve the dispersibility of high filling white fillers, making the rubber material have excellent flowability, which is beneficial for batch uniformity. Reduce the tendency of white carbon black filler to re aggregate, suitable for halogen-free rubber.
