Product Introduction: Made mainly from ultra-high strength polypropylene short fibers and produced using non-woven technology, it has functions such as isolation, reinforcement, protection, filtration, drainage, and buffering.

Product specifications: Weight of 100g to 1200g, width of 2m to 6m, length according to user requirements.

Product features: The physical and mechanical properties are 2-3 times higher than conventional products, and the proportion of products with the same weight is low; Excellent acid and alkali resistance, good hot melt adhesion, and strong wear resistance. Especially suitable for CRTS II/III slab ballastless track sliding layer system, reducing the interaction between the track system and the bridge surface.

Scope of application: polypropylene needle punched nonwoven geotextile is mainly used for the sliding layer between CRTS II type slab ballastless track and bridge beam of passenger dedicated railway, and the isolation layer between CRTS II type slab ballastless track and friction plate, and can also be widely used in expressway, railway, port, airport, coastal mudflat, reclamation, environmental protection and other fields.
