High strength polypropylene fabric specifications

PRODUCT DETAILS

DESCRIPTION:

Performance characteristics:

With ULTRA-high strength polypropylene staple fiber as the main raw material, using nonwoven process production, with isolation, reinforcement, protection, filtration, drainage, buffer and other functions.The physical and mechanical properties are 2-3 times higher than those of conventional products, and the proportion of products with the same gram weight is low; Excellent acid and alkaline resistance, good hot melt adhesion, strong wear resistance.It is especially suitable for CRTS type II/III plate-type ballastless track sliding layer system to reduce the interaction between the track system and the bridge surface.

Product specifications：SNGPP100-SNGPP1200，Width 2m ~ 6m, length according to user requirements。

APPLICATION:

Polypropylene needled nonwoven geotextile is mainly used for sliding layer between CRTS type II slab ballastless track and beam surface of passenger dedicated line railway, and CRTSII type slab ballastless track

It can also be widely used in expressway, railway, port, airport, coastal beach, reclamation and environmental protection engineering.
