N772 is a Semi-Reinforcing carbon black. Has a lower surface area and lower structure than ASTM N500 and N600 carbon blacks.
It can be used in a wide range of industrial rubber product applications, particularly in applications requiring low modulus, low compression set, good resilience and high carbon black loadings.
The higher carbon black loadings contribute to reduced swelling in adverse environments and reduced permeability. When used in association with mineral fillers offers a good compounding alternative to Thermal Blacks.
Compared to ASTM N550 and N660 carbon blacks at same phr loading, imparts to rubber compounds:
• reduced viscosity and less heat generation in processing,
• increased die swell and extrusion shrinkage,
• higher resilience and electrical resistivity,
• lower modulus
