1.1 Raw Material & Manufacturing Process

• Produced from PET polyester chips, which undergo heating, melting, and extrusion via a screw extruder.
• The molten material is spun into fibers, stretched for enhanced strength, and laid into a web structure.
• Needle-punching technology interlocks and bonds the fibers, standardizing the fabric to meet diverse application needs.

1.2 Key Performance Features

• Exceptionally high tensile strength to withstand heavy loads in engineering projects.
• Strong anti-aging properties for long-term durability under outdoor conditions.
• Resistance to acids, alkalis, and abrasion, suitable for harsh environmental exposures.
• Good flexibility for easy installation on uneven surfaces, simplifying construction processes.

1.3 Typical Application Scenarios

• Specialized use in landfill sites, tailings ponds, heavy metal remediation landfills, and saline-alkali marshes.
• Widely applied in highways, railways, embankments, and coastal tidal flats for filtration, separation, and drainage.

1.4 Product Specifications

• Weight per unit area: 100g/m² ~ 800g/m²
• Width: 1.0m ~ 6.6m
• Roll length: 50m ~ 200m (or customized per user requirements)
