The head is made of polypropylene and polyetheretherketone-based materials and is designed to run at an operating pressure of maximal 10 bar. All feed and eluent solutions are pumped directly into the column through tubes, to minimize dead zones and prevent fouling. 

The 1950s gave rise to the polypropylenes and polycarbonates. Other engineering resins such as Polyetheretherketone (PEEK) and polysulfones were developed later.

The most common thermosetting laminating resins are phenolics, melamines, epoxies, polyesters, silicones, and polyimides. Thermoplastic resins used in making laminates include polysulfone, polyphenylene sulfide, polyetheretherketone, polyamide-imide, polybutylene terephthalate, nylon 6, and polypropylene. 

Liq = liquid Mech = mechanical Chem = chemical. Notes for Table 4.1 1. Two-phase includes boiling and condensing duties 2. Other special alloys are frequently available 3. The maximum pressure capability is unlikely to occur at the higher operating temperatures, and assumes no pressure/ stress-related corrosion 4. Function of gasket as well as plate material 5. Function of braze as well as plate material 6. Not common 7. Not in a single unit 8. Condensing on gas side 9. PEEK (polyetheretherketone) can go to 250°C continuous use temperature 10.

The general-purpose thermoplastic polymers consist of such materials as polyethylene, polypropylene, polyurethanes, and polyvinyl chlorides. The engineering thermoplastic polymers include the polyimides, polyamideim-ide, polysulfones, polyetheretherketones, and polyphenylene sulfides. 

Depending on the application, different matrix materials are used. Among the duromers, most common are polyester and epoxy resins. Thermoplastic matrix materials are polyethylene (pe) and polypropylene (pp), but the use of thermoplastics with aromatic rings on the chain and thus with increased temperature stability also grows. One example is polyetheretherketone (peek), characterised by high toughness and a glass temperature of about 150°C. 

Third, contrary to what many processors beUeve, most plastics do not melt in the true sense of the word. Melting rigorously means that energy can be added to a material in order to change its state (solid to fluid) without changing its temperature. This behavior is limited to a few thermoplastic materials, including polyethylenes, polypropylenes, some nylons, the acetals, and thermoplastic polyester (Fig. 10.10). [There are others, such as polyetheretherketone (PEEK) and polymethylpentene, but these are relatively uncommon materi s.]...
