Rubber non-rotor vulcanization Tester

The Rubber Non-Rotor Vulcanization Tester is a precision instrument designed for the rubber processing industry to monitor and control rubber material quality. It provides rapid inspection and supports rubber basic research and formulation optimization. The tester can accurately measure scorch time, positive vulcanization time, vulcanization index, and torque parameters (maximum and minimum), offering essential data for quality control, R&D, and formula development.

Applications

(1) Rubber compound quality control: Rapid assessment of rubber material properties during production.

(2) Rubber R&D: Testing new rubber formulations and additives.

(3) Vulcanization process optimization: Determining optimal curing conditions.

(4) Material comparison: Evaluating performance differences between batches or suppliers.

(5) Rubber laboratory testing: Suitable for research institutes and industrial laboratories for basic rubber studies.

Standards

(1) ASTM D5289-95 — Standard Test Method for Rubber Property—Vulcanization Using a Moving Die Rheometer

(2) ISO 6502-1999(E) — Rubber, Vulcanized or Thermoplastic—Determination of Cure Characteristics

(3) GB/T 16584-1996 — Rubber—Determination of Cure Characteristics Using a Non-Rotating Rotor Rheometer

Advantages

(1) Accurate vulcanization measurement: Determines scorch time, positive cure time, vulcanization index, and torque with high precision.

(2) Supports formula optimization: Provides reliable data for rubber compound development.

(3) Standard compliant: Meets ASTM, ISO, and GB/T international and national standards.

(4) User-friendly operation: Simple control interface for temperature and time settings.

(5) Stable and durable: Designed for long-term use in laboratory and production environments.

Test Procedure

(1) Connect the power supply and compressed air source.

(2) Set the desired test temperature and curing time on the control panel.

(3) Load the rubber sample into the non-rotor rheometer cavity.

(4) Start the test; the swing mechanism will apply torque to the sample.

(5) Monitor the displayed data: scorch time, positive cure time, vulcanization index, and maximum/minimum torque.

(6) Stop the test after the set time, remove the sample, and record the results.

Maintenance Information

(1) Keep the instrument clean; remove rubber residues after each test.

(2) Periodically inspect the swing mechanism and torque sensor for wear or damage.

(3) Check temperature calibration regularly to ensure accurate measurements.

(4) Maintain pneumatic components, ensuring air lines and valves are free of leaks.

(5) Store in a dry, non-corrosive environment when not in use.
