Materials

PEEK, LCP, PPS and self-lubricating compounds — properties compared, grades, and achievable tolerances. The data you need to choose a material before the tool exists.

Indicative values

The axes a design engineer actually selects on. Values are indicative for the polymer family — a specific grade will differ.

	PEEK	LCP	PPS	LNP
Continuous service temp.	250 °C	240 °C	220 °C	per base resin
Melt temperature	360–400 °C	280–350 °C	300–330 °C	per base resin
Minimum wall	0,5 mm	< 0,3 mm	0,6 mm	per base resin
Moisture uptake	≈ 0,5 %	effectively zero	effectively zero	per base resin
Chemical resistance	very high	high	high	per base resin
Coefficient of friction	low	medium	medium	very low
Dielectric performance	good	excellent	good	per base resin
Relative material cost	very high	high	medium	medium

2 grades

PPS

Polyphenylene sulphide

Chemistry, temperature and dimensional stability at once.

Continuous service temp.: 220 °C
