Core Technical Advantages of Tailin PES Membranes

Natural Hydrophilicity and Superior Water Flux

Tailin's PES membranes feature inherent hydrophilicity without requiring surface modification treatments, enabling excellent wettability and immediate filtration performance upon contact with aqueous solutions . This natural property eliminates pre-wetting steps, reduces processing time, and delivers super high water flux—critical for high-volume production environments. The membranes maintain consistent flow rates even under challenging conditions, ensuring reliable throughput throughout the filtration process.

Innovative Asymmetric Pore Architecture

The asymmetric pore structure represents a fundamental engineering breakthrough in Tailin's PES membrane design. Standard PES flat membranes utilize a gradient pore distribution that maximizes dirt-holding capacity while maintaining high retention efficiency . For biopharmaceutical applications demanding the ultimate balance between safety and throughput, Tailin developed the proprietary Filtailin® XA Series featuring an hourglass-shaped asymmetric structure. This innovative design positions the dense separation layer in the membrane's center, protecting it from mechanical damage during handling and processing while optimizing the critical balance between selectivity and flux .

Low Protein Binding and Broad Chemical Resistance

Tailin PES membranes exhibit remarkably low protein adsorption and minimal extractable levels—essential characteristics for biopharmaceutical applications where product recovery and purity are paramount . The membranes demonstrate excellent resistance to acidic and alkaline solutions across a wide pH range, coupled with outstanding thermal stability (glass transition temperature of 225°C). This robust chemical compatibility ensures membrane integrity during aggressive cleaning protocols and compatibility with diverse process fluids in pharmaceutical, food, and industrial applications .

Tailin's Comprehensive PES Membrane Portfolio

Standard PES Flat Membranes

Tailin offers standard PES flat membranes in multiple pore sizes (0.1μm, 0.22μm, 0.45μm, 0.65μm, and 0.80μm) with 270mm width rolling film formats . These membranes deliver high porosity, uniform pore distribution, and excellent mechanical strength for applications ranging from sterilization filtration and bacterial reduction to clarification processes in food & beverage, microelectronics, and water treatment facilities.

Reinforced PES Flat Membranes

For applications requiring enhanced durability and thermal bonding capabilities, Tailin's reinforced PES membranes incorporate a support layer beneath the polyethersulfone casting . Available in 0.22μm and 0.45μm pore sizes with 254mm or 270mm widths, these membranes provide superior mechanical strength while maintaining natural hydrophilicity and low protein binding—ideal for precision infusion filters, drip funnel applications, and demanding biopharmaceutical processes .

Filtailin® XA Series: Next-Generation Biopharma Filtration

The Filtailin® XA Series represents Tailin's pinnacle achievement in PES membrane engineering. Validated through rigorous testing, these membranes maintain stable bubble points after 100 consecutive steam sterilization cycles at 121°C—demonstrating exceptional thermal durability unmatched by conventional membranes . Performance testing under 0.1MPa pressure shows significantly higher total throughput compared to competitor membranes when filtering both tap water and complex fluids like jasmine honey tea, proving superior real-world filtration efficiency .

Diverse Application Spectrum

Tailin PES membranes serve critical roles across multiple industries: sterilization filtration in pharmaceutical manufacturing, bacterial reduction in medical devices, precision clarification in semiconductor production, microbial testing in laboratories, and quality control in food & beverage processing . Their compatibility with autoclave, ethylene oxide (EO), and gamma irradiation sterilization methods provides flexibility for diverse validation requirements while maintaining membrane integrity throughout repeated sterilization cycles .

Tailin SciTech's PES membrane technology exemplifies how material science innovation translates into tangible operational advantages—higher throughput, enhanced product safety, reduced downtime, and superior cost efficiency. By combining natural hydrophilicity, intelligent pore architecture, and exceptional chemical/thermal resistance, Tailin delivers filtration solutions that empower industries to achieve new levels of efficiency and reliability in their most critical separation processes.

Moving forward, Tailin will continue to uphold its mission of supporting scientific advancement and protecting human health.
