Premier™ ESR


Encapsulated Sample Rheometer

The Premier™ ESR is designed for the composite, thermoset, and thermoplastic industries. The ESR can characterize resins and composite materials in a single test, measuring dynamic mechanical properties before, during, and after cure.

Features

  • Measure prepreg viscosity, gel point, cure, and final modulus in a single test without removing resin from fiber
  • Optimize curing conditions for consistent product quality
  • Improve incoming raw material quality
  • Check quality of shelf-aged materials
  • Test under isothermal conditions, temperature ramp & hold, or mimic the cure in an oven or autoclave
  • Rapidly evaluate materials from new sources
  • Reduce waste, improve efficiency, and reduce cost
  • Includes pressure transducer for pressure measurement
  • Operates using Enterprise software, a flexible LIMS system based on an open SQL database platform
