Description
Premium NSF 44 Certified Cation Resin for Potable Water Softening
The Franklin FWXC008 Strong Acid Cation Resin is a high-performance, food-grade ion exchange resin engineered for potable water softening and food & beverage applications. Manufactured using sulfonated styrene-divinylbenzene (DVB) copolymers, this gel-type resin delivers consistent performance, high capacity, and long service life.
Certified to NSF/ANSI 44 and compliant with FDA 21 CFR 173.25, FWXC008 meets strict standards for safe use in drinking water systems.
With excellent chemical, physical, and thermal stability, this resin provides reliable softening performance in both regenerable systems and cartridge-based applications.
Key Features
- NSF/ANSI 44 certified for potable water softening
- FDA compliant (21 CFR 173.25) for food-grade applications
- Strong acid cation (SAC) resin – 8% crosslinked
- High exchange capacity for efficient hardness removal
- Superior ion exchange kinetics for faster performance
- Excellent chemical and thermal stability
- Works in regenerable softeners and non-regenerable cartridges
- Manufactured with uniform bead size distribution for consistent flow

Food-Grade Performance Metrics
Designed for sensitive applications:
- Low extractables and minimal odor
- Low TOC (0–30 mg/L)
- Controlled color throw within acceptable limits
This ensures clean operation without contaminating treated water or beverages.
Typical Applications
- Residential and commercial water softeners
- Municipal potable water systems
- Food & beverage processing
- Pre-treatment for reverse osmosis systems
- Cartridge-based softening systems
Why This Resin Stands Out
Most resins look the same on paper. This one doesn’t.
- Certified (NSF + FDA) → eliminates compliance risk
- Tight bead distribution → consistent flow and pressure performance
- High durability → longer service life, fewer replacements
- Broad operating range → performs in demanding environments
Frequently Asked Questions (FAQs)
Is this resin safe for drinking water systems?
Yes. It is NSF 44 certified and FDA compliant, making it safe for potable water applications.
What does “8% crosslinked” mean?
It refers to the divinylbenzene content, balancing capacity, durability, and resistance to fouling.
Can this be used in standard water softeners?
Yes. It is designed for both regenerable softeners and cartridge systems.
What is the benefit of gel-type resin?
Gel-type resins provide high capacity and efficient ion exchange kinetics for standard softening applications.
What industries is this best suited for?
- Water treatment
- Food & beverage
- Municipal systems
- Commercial facilities
