The polymer for polypropylene fibre is manufactured from the parent substance propene. The fibre is subsequently produced using a melt spinning process.
Polypropylene fibres are characterised by their outstanding resistance to chemicals and hydrolysis. They can be attacked only by strong oxidation. They are used at temperatures up to 90°C under conditions where polyester cannot be used owing to chemically aggressive environment.
Typical fields of application:
|Temperature resistance||Continuous: 90 °C/Peak: 100 °C|
|Melting point||160–175 °C|
|Moisture pick-up||0 % at 65 % relative humidity and 20 °C|
|Resistance to hydrolysis||Excellent|
|Resistance to oxidation||Poor|
|Resistance to solvents||Good|
