The Computer Controlled Torque Rheostat Tester simulates industrial mixing on a lab scale. A material sample in a heated chamber with rotating blades generates torque as it resists rotor motion. A transducer measures this torque in real-time. The computer controls chamber temperature and rotor speed per a test profile, presenting data as a torque-time curve for analyzing material behavior.

Application

Materials Science: An ideal instrument for studying the flow, plasticity, thermal, and shear stability of materials.
Food Industry: Used to test the rheological properties of food materials, such as the mixing of multi-component materials, the cross-linking and curing of thermosetting resins, and the vulcanization of elastomers.
Chemical Industry: Used to study the rheological characteristics of chemical materials, such as the rheological properties of polymer melts, suspensions, coatings, inks, and food.
Geological Engineering: Used for rheological characterization of geological materials, such as the flow and deformation characteristics of rocks and soils.

Standard

(1)ASTM D2538:Standard Practice for Fusion of Poly(Vinyl Chloride) (PVC) Compounds Using a Torque Rheometer

(2)ISO 305:Plastics - Determination of thermal stability of poly(vinyl chloride), related chlorine-containing homopolymers and copolymers and their compounds - (3)Discoloration method

Advantages

(1)Characterizes Material Processability: Provides direct measurement of how materials behave during mixing and processing under controlled conditions.

(2)Evaluates Thermal and Shear Stability: Helps determine a material's resistance to degradation under heat and mechanical stress.

(3)Simulates Industrial Processes: Replicates key aspects of industrial mixing, extrusion, and other processing operations on a laboratory scale.6

(4)Objective and Quantitative Data: Generates precise torque-time curves and other data for analysis and comparison.

(5)Computer Controlled Precision: Automated control of temperature, speed, and test duration ensures high repeatability and accuracy.

(6)Versatile for Various Materials: Applicable to a wide range of polymers, elastomers, ceramics, food products, and other materials that undergo viscous processing.

(7)Supports R&D and Quality Control: Essential tool for material development, formulation optimization, and ensuring consistent product quality.

(8)Identifies Material Behavior Stages: The torque curve clearly shows different phases of material transformation during processing (e.g., melting point, fusion time, degradation onset).
