Cerulean SB 02: Softer-Grade Styrene-Butadiene Rubber for Industrial Use
Cerulean SB 02 is a copolymer of styrene-butadiene (SBR), compounded with carbon black for good abrasion resistance and excellent impact strength. With a slightly softer 70±5 Shore A hardness than other Cerulean SB grades, it’s built for general mechanical rubber goods across automotive, industrial and cable wire applications where flexibility matters alongside durability.

Cerulean SB 02 properties
ISMAT manufactures Cerulean SB 02 as a carbon black compounded SBR, validated through in-house testing to ensure consistent quality across every batch. At 70±5 Shore A, this is a softer grade compared to other Cerulean SB compounds, offering good abrasion resistance and excellent impact strength while retaining more flexibility for applications that call for it.
This balance of softness and durability makes Cerulean SB 02 a practical fit for automotive and industrial mechanical rubber goods, as well as cable wire applications, where the material needs to absorb impact and resist wear without excessive stiffness. Its operating range of -40°C to +100°C covers most general-purpose industrial and automotive conditions.
