rigid resins for non-aqueous applications
Temiz Polar RP Resins

The majority of resins, adsorbents, ion-exchangers currently on the market are optimized for use in aqeuous matrices, ie water and water-rich solutions. However, no satisfactory resins are offered that retain their physical morphology in hydrophobic solvents. Conventional resins with their low cross-linkage suffer either collapse or non-compatibility in eg organic solvents, oils, etc.

Redstone has developed a set of highly rigid resins for use in non-aqueous solutions such as organic solvents, complex extracts, supercritical CO2, essential and natural oils and other hydrophobic matrices. These new resins are unique and offer performance and functionality in hydrophobic environments where conventional resins do not perform. The different resins offer a good variation of different surface chemistries and thus different selectivities.

Examples of potential application in oils / hydrophobic liquids:

  • Removal of unwanted contaminants
  • Retrieval of valuable compounds
  • Fractionation of complex mixtures
  • Solid Phase Extraction after Liquid-Liquid Extraction
  • Work-up / Clean-up of organic synthetic reactions


Examples of areas of use:

  • Synthetic organic chemistry
  • Lipid production
  • Lipidomics
  • Food oils
  • Essential oils
  • Hemp oils
