1. It is often used to treat carbon black, inorganic fillers such as SiO2, and it has the function of activator and coupling agent.
2, also has the role of cross-linking agent, softener and reinforcing agent,
3. As a reinforcing agent and vulcanizing agent in the rubber industry.
4, can be used for natural rubber, isoprene rubber, styrene butadiene rubber, butadiene rubber, butyl ester rubber, neoprene, butyl rubber, halogenated butyl rubber, EPDM rubber and oil-filled of these rubber Glue can also be used in the combination of these rubbers.
5, applied to sulfurized rubber, can improve cross-linking stability, tear resistance, shear resistance, water resistance, etc., reduce compression deformation.
6. Suitable inorganic fillers: carbon black, white carbon black, glass fiber, talc, mica, fly ash, clay, etc.
7. Applicable rubber products, tires (tread, carcass, outer wall), solid rubber tire roller surface. Conveyor belt surface, steel brush wire bond, cable (extreme layer and wrap), shoes (return shoes, marathon shoes, tennis shoes).

5L, 10L, 25L, 200L PE drum or 1000L IBC container. Customized service is acceptable. Please specify when order.
