    Universal thermoplastics with good chemical resistance that can be used at temperatures up to 80° C, for example:

    • Polyethylene (PE)
    • Polypropylene (PP-H, PPs)
    • Polyvinylchloride (PVC-U)
    • Polyetheretherketone (PEEK)
    • TIVAR® or Quicksilver® lining-material

    Fluoroplastics with outstanding chemical resistance and high purity that can be used at temperatures up to 260° C, for example:

    • Polyvinylidenfluoride (PVDF)
    • Ethylene-Chlortrifluoroethylene (E-CTFE)
    • Tetrafluoroethylene-Perfluoroalkyl vinylether (PFA)
    • Tetrafluoroethylene-Hexafluoropropylene(FEP)
    • Polytertafluorethylene – Teflon (PTFE / PTFE with carbon / PTFE with glass)

    Thermoplastics for special applications:

    • Polymethyl methacrylate(PMMA) – plexiglass/acrylic glass
    • Polyethylenenterephtalatmite Glycol (PETG)
    • Polycarbonate (PC)
    • Polyetheretherketone (PEEK)
    • Polyamide (PA)
    • Polyoximethylene (POM)

    Duroplastics - glass fibre reinforced plastics (GFRP)

    Can withstand high levels of mechanical stress, while also being resistant to corrosion, acids and temperatures up to 200° C

    • Epoxide resin
    • Vinyl ester resin
