Technology Marketing Summary

The Extrans Permeation Measurement System is a customizable system for testing the behavior and uniformity of polymers and other materials. The system can be used to determine permeation rates using variable temperatures, total pressures, differential pressures, and mechanical deformations as well as adjustable concentration levels for gases and liquids. Extrans supports permeation testing from liquid-to-gas or from gas-to-gas phases.

  • User-selected temperature and pressure ranges
  • Balanced differential pressure manifold incorporating a back-pressure control valve and regulator
  • Adaptable for different materials from sheet, thin pads, to tubes and bulk materials
  • Programmable for repetitive or complex tasks
  • Compact design
  • Versatile – Able to handle varying degrees of pressure and temperature
  • Precise – Accurately measures permeation rates
  • Portable – Can be used for field testing
  • Effective – Can induce stress in materials to determine the effect on permeation rates
Applications and Industries
  • Container analysis and design for storage of food, munitions, and moisture-reactive materials
  • Materials analysis of conformal coatings for electrical circuit components used in marine, aerospace, defense and other critical applications
  • Corrosion studies
  • Coating, film and paint evaluation

Fluid permeability measurement system and method
A system for measuring the permeance of a material. The permeability of the material may also be derived. The system provides a liquid or high concentration fluid bath on one side of a material test sample, and a gas flow across the opposing side of the material test sample. The mass flow rate of permeated fluid as a fraction of the combined mass flow rate of gas and permeated fluid is used to calculate the permeance of the material. The material test sample may be a sheet, a tube, or a solid shape. Operational test conditions may be varied, including concentration of the fluid, temperature of the fluid, strain profile of the material test sample, and differential pressure across the material test sample.
