DuPont IntegraTec™ XP 77 IG FDA Compliant L for Pharma and Beverage
-
Product Description:
The DuPont UF XP 77 IG is a high-performance ion exchange membrane designed for chlor-alkali electrolysis applications. It delivers high current efficiency (≥96%) and low energy consumption, enabling cost-effective production of caustic soda (NaOH), chlorine (Cl₂), and hydrogen (H₂). The membrane features exceptional chemical resistance to harsh brine environments and low gas permeability, ensuring long-term stability in industrial electrolyzers. With optimized thickness (0.2–0.3 mm) and low voltage drop, it maximizes productivity while reducing operational costs. Certified for use in membrane cell electrolysis plants, the XP 77 IG is engineered for durability (>5 years service life) and consistent performance under high-load conditions.
Key Features:
-
Ultra-Strong PVDF Membrane Material – Resists tearing, abrasion, and chemical degradation.
-
Superior Chemical Tolerance – Withstands aggressive cleaning agents and extreme pH conditions.
-
Outer-to-In Filtration Design – Handles high solids content and turbid feed water with minimal fouling.
-
Precision-Level Filtration Efficiency – Removes microorganisms, colloids, and fine particulates effectively.
-
Optimized for Heavy-Duty Systems – Ideal for large-scale industrial installations requiring extended service life.
Applications:
-
Industrial Wastewater Reclamation (chemical processing, mining, power generation)
-
Seawater Pretreatment for Desalination Plants
-
Aggressive Process Water Treatment (textile dyeing, metal finishing, petrochemical)
-
Municipal Water Purification in High-Stress Environments
Technical Highlights:
-
Material Science: Hydrophilic PVDF with enhanced structural integrity
-
Filtration Mechanism: Outer-pressure configuration for high solids tolerance
-
Operational Resilience: Broad chemical and thermal operating window
-
Certifications: Meets international standards for industrial water safety
Competitive Advantages:
The XP 77 IG stands apart through its uncompromising resilience in corrosive and high-load environments. Its advanced polymer formulation resists common membrane failure modes, while the optimized fiber geometry balances flux stability with energy efficiency. This membrane is engineered to reduce lifecycle costs in applications where conventional UF membranes degrade prematurely.
