Facilities available for quality control at united rubber

RHEOMETER

with the help of this versatile equipment meant for quality control and R&D work, compound propoerties like thermoplacticity, processing safety, cure rate, optimum cure time and ultimate state of cure are measured and monitered.

MOONEY VISCOMETER TO TEST PROCESSING CHARACTERISTICS

This highly sophisticated instrument is used to determine the plasticity and scorch [curing] behaviour of tread rubber compounds and other retreading inputs. Strict monitoring of plasticity and scorch behaviour of these compounds is of prime importance in the manufacture of tread .rubber and attendant items like bonding gum/ cushion gum, filler gum, precured process solution etc.

SPECIFIC GRAVITY BALANCE TO CONDUCT SPECIFIC
GRAVITY TEST

Specific gravity, a good guide for assessing the uniformity of mixed rubber compounds, is determined using the direct reading specific gravity balance.

HARDNESS DURO METER TO MEASURE CURED HARDNESS

Hardness, the most often measured property of cured tread rubber and repair materials is determined using Hardness Duro Meter.

TENSILE TESTER TO STUDY STRESS-STRAIN PROPERTIES

Tensile strength and ultimate elongation measurements are indispensable parameters of rubber compounds and are considered an Index to general, all-around quality. Similarly, tensile stress, commonly called modulus, another important property of tread compounds is also examined with the tensile tester.

DIN ABRASION TESTER TO FIND OUT ABRASIVE WEAR

Resistance to abrasion is an important property in tyre treads and is .gauged by studying the loss in volume of a sample abraded under standard conditions with an abrasive medium mounted on a rotating drum. Due to the variability in service conditions, accurate predictions from abrasion tests may not possible. however, the standard tests bear some resemblance to the kind of abrasion a tyre tread gets and so this equipment plays an important role in the designing and developement .of tread compounds capable of giving extremely good mileage.

GADGETS FOR CONDUCTING CHEMICAL TESTS

Routine chemical tests are conducted to make sure the most desirable quality of organic and inorganic ingredients that go into the making of all retreading inputs. Melting point tests, solubility determination, iodine value , pour density , viscosity tests, pH determination, DBP absorption, Acetone extract, Aniline point, flash point, Acid value, Ash content etc are some of these.

DISPERSION ANALYSER FOR CHECKING DISPERSION OF CARBON BLACK IN RUBBER COMPOUNDS

Rate of dispersion of fillers and chemicals in the rubber matrix is of utmost importance in predicting the final product properties, and Dispersion Analyser is used as an important quality control tool to ascertain the efficiency of dispersion. Major properties of cured rubber compounds like Tensile Strength, Abrasion Resistance, Tear Resistance etc are dependent on the effectiveness of dispersion.

By undertaking these multifarious and diversified tests, checks and experiments, United Rubber’s pursuit of excellence has become a continuous process.
