Physicochemical properties:
Spraying carbon black is a large particle size, high structure furnace black, with a particle size of 100~130nm, an iodine absorption value of 15g/kg, similar to natural gas semi-reinforcing furnace black, between Carbon black N700 Between the carbon black M900 series, but its structure is much higher than the natural gas semi-reinforcing furnace black, DBP absorption value is 120cm3/100g.
Uses:
Used as a reinforcing filler for rubber.
Usage and function:
This product can be filled in a large amount in the rubber compound, with good processing performance and small extrusion shrinkage. Vulcanized rubber has high elasticity, low heat generation, small deformation, good low temperature performance, high stress at definite elongation, but low tensile strength and tensile elongation.
