polypropylene filament geotextile

Polypropylene has the characteristics of very weak polarity, anti-swelling and, therefore, polypropylene silk geotextile has good acid and alkali resistance and freeze and thaw resistance, so that It is irreplaceable in the engineering application of acid and alkali environment and high and cold region function of. However, the polypropylene molecular chain contains less tertiary hydrogen atoms Stability, resulting in poor thermal stability and UV resistance Low line capacity defects, greatly limited it in high temperature or tropical landThe use of district. Although significant after the addition of antioxidants or photostabilizers, etc
