SFP/SFD2880 Ultrafiltration Membrane for Electronic Grade Ultrapure Water DuPont Equivalent

Product Introduction

LEFILTER is proud to unveil the SFP/SFD2880 Ultrafiltration Membrane for Electronic Grade Ultrapure Water, an advanced membrane module tailored for the highly specialized water treatment demands of microelectronics and semiconductor manufacturing. Engineered as a high-precision DuPont equivalent, this ultrafiltration membrane guarantees outstanding retention of colloidal particles, microorganisms, and submicron impurities, thereby safeguarding the integrity of ultrapure water systems where even the slightest contamination can disrupt critical production processes.

The SFP/SFD2880 model features an enlarged membrane area and optimized flow dynamics, enabling greater throughput and stable performance under continuous operation. Manufactured with premium PVDF hollow fiber, the membrane resists chemical degradation, offers excellent mechanical durability, and delivers dependable filtration efficiency for final-stage water polishing in ultrapure applications. Its low extractables profile and minimal pressure drop characteristics make it ideal for maintaining consistent high-purity water quality.

Technical Specifications

The enhanced membrane area provides superior flux while preserving a low fouling profile, making it suitable for high-volume, high-purity water production lines.

Application Scope

The SFP/SFD2880 Ultrafiltration Membrane is expertly designed for industries and scenarios where ultrapure water is fundamental to operational success, including:

• Integrated Circuit & Chip Fabrication: Delivers ultraclean water for etching, rinsing, and photoresist removal stages—eliminating microcontaminants that could compromise lithographic accuracy.

• LCD/LED Display Panel Manufacturing: Provides particle-free and bacteria-free rinse water, critical for high-resolution screen production processes.

• Solar PV Cell Production: Used in cleaning and surface texturing stages, ensuring that wafers remain uncontaminated by organics or particulates.

• Hard Disk and Micro-optics Manufacturing: Supports defect-free lens and disk coating by supplying consistently ultrapure rinse water.

• Advanced Research Laboratories & Nanotechnology: Facilitates ultrapure water needs in precision instrument calibration, microfluidics, and high-resolution analysis.

Its compatibility with high-resistivity systems and minimal TOC leaching capability ensures complete alignment with SEMI F63 and ASTM D5127 water quality standards.
