Ertalyte petp

Ertalyte® petp is polyethylene terephthalate. It is one of the harder industrial plastics and comes in two grades - virgin or natural petp (white, black) and TX petp (pale grey), which has a uniformly dispersed solid lubricant.

The virgin or natural grade is recommended for use with precision parts which are subject to sustained high loadings and wear, whilst the TX grade has a very low friction co-efficient and a high pressure to velocity rating (a 50mm diameter x 75mm long petp bush can take a load of up to 9 tonnes).

The main uses for Ertalyte® petp are in applications which require low friction, low moisture absorption, high mechanical strength and good dimensional stability.

Temperature range: -20ºC to +100ºC
(-20°C to +55°C in water)
