In the Rubber Industry the effects of compound variations on curing characteristics are important in compound development studies or production control. In compound development, the composition of the ingredients can be varied until the desired vulcanization characteristics are achieved. For all this, the Computerized Rheometer with Micro-processor temperature controls is an equipment of vital importance. The Rubber Compounder feels handicapped without a Rheometer. The inventions of new Polymers & Rubber Chemicals leads the compounder to an embarrassing position regarding their choice & use. The Rheometer is an only equipment in the Rubber Industry which helps the Compounder to choose the right
material and its appropriate dose to meet the end requirements of the product. The Rheometer not only exhibits the curing characteristics of the Rubber Compound but it also monitors the processing characteristics as well as the physical properties of the material. The “Cure Curve” obtained with a Rheometer is a finger print of the compound’s vulcanization and processing character. In fact, the Rheometer has manifold advantages e.g. :
i) RESEARCH & DEVELOPMENT: The most tedious part in compounding is to develop a new compound. It involves:
a) Defining required quality targets.
b) Designing preliminary compounds, selecting specific ingredients and determination of dosage of each ingredient.
c) Checking the cost factor.
d) Testing each compound.
