Polypropylene is an olefin fiber which is very strong and resilient.
A manufactured olefin fiber made from polymers or co-polymers of propylene. The resulting fiber has a high degree of crystallinity (72 to 75%), so it is very strong and resilient.
Polypropylene fiber properties include:
- Lightweight (floats on water)
- Extremely low moisture regain
- Quick drying
- Highly resistant to mechanical abuse
- Mildew and insect resistant
- Chemical resistant
- Abrasion resistant
- Sunlight resistant
- Colorfast
Sample polypropylene applications:
- Filtration media
- Protective clothing
- Outerwear
- Binding materials
