The main physical and chemical properties of polypropylene high strength filament
1. Form
The longitudinal surface of polypropylene is smooth and lubricated, with a circular cross-section.
2. Density
The advantage of polypropylene fiber is its lightweight, with a density of only 0.91g/cm3. It is one of the lighter types of common chemical fibers, so polypropylene fiber with the same weight can achieve a higher coverage area than other fibers.
3. Strong extensibility
Polypropylene has high strength, elongation, initial modulus, and excellent elasticity. So polypropylene has good wear resistance. In addition, the wet strength of polypropylene is fundamentally equal to the dry strength, so it is an ideal material for manufacturing fishing nets and cables.
4. Moisture absorption and staining properties
Polypropylene has very low moisture absorption, almost no moisture absorption, and its moisture regain under normal atmospheric conditions is close to zero. But it has a core suction effect and can transmit water vapor through capillaries in the fabric, but it does not have any absorption effect on its own. Polypropylene has poor dyeing properties and incomplete chromatography, but it can be compensated for by using the original solution coloring method.
5. Acid and alkali resistance
Polypropylene has good resistance to chemical corrosion. In addition to concentrated nitric acid and caustic soda, polypropylene has good resistance to acid and alkali, making it suitable for use as a filter and packaging material.
6. Light resistance, etc
Polypropylene has poor light resistance and thermal stability, is prone to aging, and is not resistant to ironing. But it can be prevented during spinning
