Properties of some high technology plastics used in some wands. 


PEEK Polyetheretherketone


General Description
PEEK is a high temperature, high cost , semi-crystalline material with excellent mechanical properties and chemical resistance.


Brand Names
Victrex (ICI), Thermocomp (LNP)


Material Mfg.
ICI, LNP

Cost
14,000-41,000 psi with carbon fibre
440,000-2,400,000 psi
0.9-3 ft-lb/in notched izod
600F short duration 480F long term
Good to Excellent
VERY expensive



PEI Polyetherimid (Ultem)


General Description
PEI is an amorphous, high temperature material with relatively low cost compared to other high temperature materials. It has excellent elongation and Impact Strength, and can be molded to tight tolerances. Its chemical resistance is not as good as crystalline materials but is excellent for an amorphous material. PEI behaves similar to polycarbonate, but can perform at higher temperatures.

PES Polyethersulfone


General Description
Polyethersulfone is a high temperature amorphous material with relatively low cost. PES has slightly lower capabilities than PEI at about the same cost. As a result it is not widely used.

PPS Polyphenylene Sulfide


General Description
PPS is a high temperature semi-crystalline material. It has good mechanical properties and excellent chemical resistance at elevated temperatures. PPS has been compounded extensively and many different types of properties are available. PTFE filled PPS is one of the best bearing materials available. Unfilled grades of PPS have poor properties, so components are usually made from glass filled or glass/mineral filled grades. PPS is very sensitive to molding conditions and must be processed properly to achieve its maximum potential.


Brand Names
Fortron (Hoechst Celanese), Lubricomp (LNP), Ryton (Phillips), Supec (GE)
