High Pesrmeability PP 200g Nonwoven Geotextile Fabric Filtration Layer In Drainage Geotechnical Material
High Pesrmeability PP 200g Nonwoven Geotextile Fabric Application Filtration Layer In Drainage Geotechnical Material
Yixing Shenzhou 200g PP nonwoven geotextile is commonly used as a filtration layer in drainage systems due to its excellent permeability, filtration properties, and durability. Here’s a breakdown of its key features and applications:
PP 200g Nonwoven Geotextile Fabric Application Filtration Layer In Drainage Key Properties:
Material: Polypropylene (PP) – Resistant to chemicals, rot, and biological degradation.
Weight: 200 g/m² – Provides a good balance between strength and filtration efficiency.
Nonwoven Structure: Needle-punched or thermally bonded for optimal filtration.
Filtration Efficiency: Allows water to pass while preventing soil/clogging particles from entering the drainage system.
High Permeability: Ensures efficient water flow, reducing hydrostatic pressure.
UV Resistance: Suitable for temporary exposure but should be covered for long-term use.
Tensile Strength: Provides structural support in drainage applications.
