偶联剂Si-69/KH-845-4/Z-6940/A-1289/Y-6194/KBM-846

1. chemical name double - (gamma - three b oxygen radicals silane propyl) - four sulfide

2. c2h5o) 3si chemical structured (3 - s (ch2) - (s) - (s) - (s) - (ch2) 3si (c2h5o) 3

3. domestic and foreign corresponding brand kh - 845-4 (cas), si - 69 (germany), z - solid sasha) (american dow corning) 6940, a - 1289 (american compton), y - 6194 (american league carbon), kbm - 846 (japanese believe more)

4.cas: 40372-72-3

5. physicochemical properties light yellow transparent liquid, soluble in ethanol, acetone, benzene, toluene and so on many kinds of solvent, insoluble in water, but with water or moisture contact easy happening hydrolysis.

6. technical specifications project indicators appearance light yellow transparent liquid sulphur p (20 ℃) technology density 1.12 g/cm3 1.07mg 100.0 p flash points ℃

7. si - 69 not only has the properties of sulfiding agent, activator, coupling agent, also has the effect of crosslinking agent, softener and intensifier, can be used for the role of nr, nbr, sbr, ir, br, epdm, cr and these rubber oil filled with the plastic and rubber.

8. not vulcanizates role as following: to reduce door; nehemiah viscosity (2) reduce coke burning phenomenon; (3) vulcanization improves; (4), calender, pressure mixed refine the characteristic greatly improved. ?

vulcanizates tensile strength improve: (1); (2) increase strength set out; (3) permanent deformation reduced; (4) get hot and dynamic characteristics of the improved; 5 wearability improved; 6 tear strength improved resistance; in water and other substances indirectly affect the turgor embellish sex will be improved.

this product is slightly ethanol smell of the light yellow transparent liquid, soluble in ethanol, ketone, benzene, acetonitrile, dmf, dimethyl sulfone follows, chlorinated hydrocarbons, insoluble in water.

appearance: light yellow yellow transparent liquid

total sulfur (%) : 22.0 p

density (ρ 20) g/cm3:1.089 + 0.005

refractive index (n) : 1.4850 + 0.0005

often used for processing carbon black, filler, inorganic sio2 endless has activator, coupling agent, also has the effect of crosslinking agent, softener and intensifier role in rubber industry as intensifier and curing agent. can be used for natural rubber, isoprene rubber, butylbenzene rubber, butadiene rubber, butyl acetate glue, neoprene, butyl rubber, halogenating butyl rubber, triple the powder and these rubber oil filled, also in these rubber adhesive in the used with glue.

1. used in the rubber, sulfur can improve crosslinking stability, ripstop and shearing, water resistance, and etc, reducing compressive deformation, born hot sex, and water rongzhang, improved the dynamic shape characteristics.

2. suitable for rubber types: natural rubber, isoprene rubber, polybutadience rubber, butylbenzene rubber, butadiene rubber, butyl acetate glue, neoprene, butyl rubber, halogenating butyl rubber powder, triple.

3. suitable for inorganic packing: carbon black, white carbon black, glass fiber, talc, mica, fly ash, clay, etc.

4. applicable rubber products: tyres (tread, tire body, tire outer wall), solid rubber tire rubber surface. conveyor belt surface, steel brush line agglutinate content, cable (absolutely level layer and coated surface), wrapped shoes (back in shoes, marathon shoes, tennis shoes).
