Rheology

Rubber Process Analyzer (RPA)

  • Advanced dynamic rheometer
  • Measures viscoelastic properties under simulated processing conditions
  • Key outputs: - Storage modulus (elastic behavior) - Loss modulus (viscous behavior) - Payne effect (filler interaction)
  • Used for: - Compound development - Process simulation - Quality consistency

  • Industry-standard curing analysis tool
  • Measures torque vs. time during vulcanization
  • Provides: - Cure time (t90, t95) - Scorch time - Crosslink density indication
  • Essential for: - Determining curing cycles - Ensuring batch-to-batch consistency

  • Measures viscosity and scorch characteristics
  • Critical for: - Processing behavior (mixing, extrusion) - Storage stability
  • Widely used as a baseline QC parameter

  • Prevents sample loss and contamination during testing
  • Ideal for: - Low-viscosity or volatile compounds - High-precision, sealed testing environments
