How Can We Help?

Lab Technology

Return Polymers has continually upgraded the technology and systems in the development and Quality Assurance labs. The facility is capable of performing the following procedures and methods:

  • Material Identification and characterization. 
  • Contamination Studies [ RPLP005]
  • Bulk Density [ASTM D1895, Method A]
  • Funnel Flow [ASTM D1895, Method A]
  • Specific Gravity
  • Extrudability [RPL002]
  • Gardner Impact [instantaneous, after aging, post water immersion] [ASTM D4226-05]
  • Torque Rheological Studies – [fusion time, fusion temperature, equilibrium torque]
  • Dynamic Stability Studies
  • Particle Size Distribution [ RoTap Standard Methods]
  • Hunter / CIE*Lab Color Analysis [ Colorite]

Third party contract services are used when additional testing or development is essential.
