Long Fibers PP Nonwoven geotextile Introduction

Long Fibers PP nonwoven geotextile is spunbonded needle-punched geotextile, a high-performance geosynthetic material. It is produced by advanced production equipment imported from Italy and Germany. Its performance exceeds the Chinese national standard GB/T17639-2008.

Functions

Long fibers PP geotextile possesses all typical functions of nonwoven geotextiles and delivers superior mechanical and physical properties compared with other nonwoven geotextile products.

Application

1. Transportation projects: Used for reinforcement, protection, separation, filtration and drainage blind ditches for highway and railway subgrade; sliding and isolation layers for high-speed railways; reinforcement for airport aprons and runways, harbor projects. PP nonwoven geotextile must be adopted where direct contact with cement occurs to avoid unnecessary losses.

2. Water conservancy projects: Dam construction, land reclamation, anti-seepage works, vertical anti-seepage projects, cement dam reinforcement.

3. Environmental protection works: Landfill projects, gold heap leaching sites, solid waste landfills.

Due to the high manufacturing difficulty of PP filament nonwoven geotextile, its market price is generally high in this industry. We strive to offer competitive pricing for this product, aiming to deliver more benefits for global geosynthetic engineering applications.
