This product is one of the most excellent additives for rubber processing products. It is a compound with an amphoteric structure. Part of its genes in the molecule can interact with inorganic fillers (such as carbon black, white carbon black, glass fiber, talc, mica, fly ash). , Clay, etc.) surface chemical gene reaction to form a strong chemical bond. Another part of the gene can react with organic macromolecules to form a physical entanglement, thus, like a bridge, the inorganic reinforcing material or filling and the organic polymer (rubber molecule) are tightly integrated into one body. This product is the same as Si-69 produced by German Di Gaosha Company, suitable for natural rubber, styrene butadiene rubber, nitrile rubber, neoprene, butyl rubber, butadiene rubber, isoprene rubber, ternary ethylene Among various rubber products such as acrylic rubber, it is especially suitable for rubber products with carbon black and white carbon black as fillers. It not only has a good reinforcing effect, but also has the functions of a vulcanizing agent and an activator, thereby improving It improves the mechanical strength and wear resistance of the product, reduces permanent deformation, heat build-up and swelling in water, greatly improves the dynamic characteristics of the product, and greatly increases the service life of the product. This coupling agent is mainly used in various tire (tread or carcass) rubber rollers, conveyor belt surfaces, steel brush wire adhesives, cable insulation layers, cable coatings, and various rubber products such as rubber shoes, shoe soles, etc. , Extremely versatile.

Packing: 25kg, plastic drum.
