The tester is used to verify how well carbon black and fillers have been mixed into rubber compounds, helping to confirm that mixing procedures deliver a uniform compound.
It supports dispersion checks on compounds used in tyres, seals, hoses, and other automotive rubber components where consistent filler distribution is important for durability.
The instrument helps assess filler dispersion in rubber sheets, profiles, belts, and other industrial rubber products.
It can be used to compare different carbon black grades, suppliers, and production batches by evaluating their dispersion behavior in a given formulation.
The tester is suitable for compound development, mixing process optimization, formulation comparison, and routine quality control testing.
