What is PP?
PP stands for polypropylene. It is a part-crystalline thermoplastic, which is supplied as sheets or rods. We stock PP in grey and natural colours.
Polypropylene is known under the brand name TECAFINE®.
The characteristics and applications of polypropylene
PP has high rigidity and good chemical resistance. The material is also electrically insulating and has very low water absorption.
For this reason, we often recommend PP for use in wet environments, where cleaning is with chemicals. PP can withstand damp and harsh cleaning materials.
Please note that PP is not strong when exposed to cold, hence its low impact resistance. In cold areas, PEHD or PTFE are better alternatives, depending on other requirements in the given environment.
We use PP for instance in hinged items, since the material can cope with repeated bending without breaking.
However, PP loses rigidity at high temperatures. It can withstand only 100 °C and it is also affected by UV.
Note also that PP is not suited to mechanical wear as it can cold flow.
We can CNC turn or mill your PP parts in our production plant.
PP does not have FCM approval as standard, but it is available in an FCM-approved version.
