Product Description
The DuPont IntegraTec XP 51 IG is an advanced ion exchange membrane engineered for high-efficiency chlor-alkali electrolysis, delivering superior performance in caustic soda (NaOH), chlorine (Cl₂), and hydrogen (H₂) production.
Designed with DuPont's proprietary IntegraTec technology, this membrane ensures exceptional current efficiency (≥96%) and low energy consumption, optimizing operational costs in membrane cell electrolyzers. Its reinforced perfluorinated polymer structure provides outstanding resistance to harsh chemical environments, including concentrated brine and high-temperature conditions.
The XP 51 IG features low gas permeability and stable voltage drop, ensuring consistent output and extended service life (typically >5 years). Ideal for modern electrolysis plants, it supports sustainable production with reduced power requirements and minimized caustic impurities.
Why Choose the XP 51 IG?
Smarter Filtration, Unmatched Purity
Proprietary pore structure technology ensures superior removal of pathogens, microplastics, and colloidal particles while preserving vital minerals for safer, cleaner water outcomes.
Ultra-High Efficiency
Engineered with DuPont's cutting-edge hydrophilic polymers, the XP 51 IG achieves up to 20% higher flux rates compared to conventional membranes, translating to faster processing and energy savings.
Built for Tough Conditions
Exceptional resistance to chlorine, pH extremes, and organic fouling ensures reliable operation in industrial wastewater, brackish water, or high-turbidity applications.
Sustainable by Design
Reduced fouling tendencies and easy-to-clean surfaces minimize chemical usage and downtime, supporting eco-conscious operations and lower lifecycle costs.
Plug-and-Play Compatibility
Seamlessly integrates into modular filtration systems, offering scalable solutions for both retrofits and new installations.
