Product Description
Product Introduction:
Using ultra-high-strength polypropylene staple fiber or ES fiber as the main raw material, it is produced by non-woven technology and has the functions of isolation, reinforcement, protection, filtration, drainage, and buffering.
Product specifications: PP100~PP1200, width 2m~6m., length according to user requirements.
Features:
The physical and mechanical properties are 2 to 3 times higher than that of conventional products. The proportion of products with the same gram weight is low; the acid and alkali resistance is excellent, the hot melt adhesion is good, and the wear resistance is strong. It is more suitable for CRTS/ slab ballastless track sliding layer system, which can reduce the interaction between the track system and the bridge surface.
Applications:
Polypropylene needle-punched non-woven geotextile is mainly used for the sliding layer between CRTS slab ballastless track and beam surface of passenger dedicated railway, and the isolation layer between CRTS slab ballastless track and friction. It can also be widely used Hydropower, highways, railways, ports, airports, sports venues, tunnels, beaches, reclamation, environmental protection and other fields play the role of isolation, filtration, drainage, reinforcement, protection, etc.

Pro
Product Application
1. Road Work
Geotextiles are widely used in the construction of the road. It reinforces the soil by adding tensile strength to it. It is used as a rapid de-watering layer in the roadbed, the geotextiles need to preserve its permeability without losing its separating functions.
2. Railway Works
The woven fabrics or the non-woven ones are used to separate the soil from the sub-soil without impeding the groundwater circulation where the ground is unstable. Enveloping individual layers with fabric prevents the material from wandering off sideways due to shocks and vibrations from running trains.
3. Agriculture
It is used for mud control. For the improvement of muddy paths and trails those used by cattle or light traffic, nonwoven fabrics are used and are folded by overlapping to include the pipe or a mass of grit.
4. Drainage
The use of geotextiles to filter the soil and a more or less single size granular material to transport water is increasingly seen as a technically and commerc
