In recent years, as the most cost-effective and highly flexible nonwoven technology, imported PP polypropylene filament nonwovens have occupied a large share of the domestic market. This is largely due to its use in Today we will take a closer look at the important status of each field.
Imported PP polypropylene filament non-woven fabric is a non-toxic, odorless and tasteless milky white highly crystalline polymer with a density of only 0.90–“0.91g/cm3. It is one of the lightest varieties of all plastics at present.
It is particularly stable in water, with a water absorption rate of only 0.01% and a molecular weight of about 80,000 to 150,000.
The formability is good, but due to the large shrinkage rate (1%~2.5%), thick-walled products are easy to dent, and it is difficult to meet the requirements for some parts with high dimensional accuracy, and the surface gloss of the product is good.
Polypropylene filament geotextile can form a strong three-dimensional structure after acupuncture, and its tensile strength and uniformity are better than polyester filament.
Although polypropylene requires special ultraviolet resistance treatment to meet the requirements of long-term exposure, geotextiles are generally not exposed to the sun or leakage in the air during construction, and the requirements for sun resistance are not high. Corrosion resistance and aging resistance are the foundation of quality assurance.
