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.
Certifications & Compliance:
Our 200g PP nonwoven geotextile meets or exceeds the following standards:
ISO 9001:2015 Quality Management System
CE Marking for construction products
