PEEK 151 is a high-performance thermopolymer resistant to high temperatures and many chemicals. It is a common injection moulding plastic for industrial applications where high strength and low weight are desirable.

PEI is a high performance thermoplastic wither outstanding strength and thermal stability. It is often used for structural parts due to its high strength to weight ratio.

PPSU is a high performance thermopolymer with good resistance to certain chemicals and good resistance to temperature.
