REGAL® SRF

REGAL® SRF by Cabot is a carbon black in the class known as Semi-Reinforcing Furnace (SRF) carbon blacks. It has a lower surface area than ASTM N500 and N600 carbon blacks and a structure lower than ASTM N774 carbon black.

• It exhibits reduced viscosity, less heat generation in processing, increased die swell and extrusion shrinkage.
• It possesses higher resilience, electrical resistivity, lower modulus, tensile strength and compression set.
• It contributes to reduced swelling in adverse environments and reduced permeability. In association with mineral fillers, it offers a good compounding alternative to thermal blacks.
• REGAL® SRF is used in a wide range of industrial rubber product applications such as gaskets, seals, windscreen wiper blades, engine mountings, hose linings, tire tubes and inner-liner compounds.
