Ultem is synthesized through a polycondensation reaction, forming a high-strength polyetherimide resin.
01 | Polymerisation
The resin undergoes purification to remove byproducts and is pelletised for ease of transport, storage, and downstream manufacturing.
02 | Purification & Pelletisation
Pellets are melted and shaped into precise forms using injection moulding or extrusion, depending on the application.
03 | Injection Moulding & Extrusion
Final parts can be sterilised via autoclave, gamma, or EtO methods, making Ultem suitable for medical and high-performance use.
