Polypropylene Fibre Characteristics
Polypropylene fibre (PP) is an olefin fibre, olefin fibres float on water as they have the lowest specific gravity of all fibres.
- MFP (Multi-filament Polypropylene) – This fibre yarn is made with many long continuous filaments measuring less than 0.1mm in diameter. This fibre has a soft feel and
- Mono-filament Polypropylene – This yarn is made with single filaments ranging in diameters from 0.03mm to 0.3mm, products made with mono-filament polypropylene are very coarse and generally do not feel nice to the touch.
|Stretch||High, ~15% stretch while pulling @ 30% of the minimum tensile strength|
|Weight||Very light (0.94 SG)|
|Melting point||300°F (149°C)|
|Bleaches / Solvents||Excellent|
|Weak acids / alkali||Excellent|
|Strong acids / alkali||Excellent|
|Abrasion resistance||Poor – Good|
|Mildew / ageing / UV||Excellent resistance to mildew / adequate UV*|
*UV resistance can be improved by adding a UV resistant coating.
Standard ABL products made with this fibre include Brizo™, Double-Lite™.
