Franklin FWXC010 Strong Acid Cation Resin – NSF 44 Certified Food Grade Water Softening Resin (10% Crosslinked)

High-Durability 10% Crosslinked Resin for Demanding Water Softening Applications

The Franklin FWXC010 Strong Acid Cation Resin is a premium, food-grade ion exchange resin engineered for potable water softening and food & beverage processing. Manufactured using sulfonated styrene-divinylbenzene (DVB) copolymers with 10% crosslinking, this resin delivers enhanced durability, higher resistance to degradation, and longer service life compared to standard 8% resins.

Certified to NSF/ANSI 44 and compliant with FDA 21 CFR 173.25, FWXC010 meets strict requirements for safe use in drinking water systems.

Its high crosslink density provides superior resistance to attrition, oxidation, and fouling, making it the preferred choice for more demanding or variable water conditions.

Why Choose 10% Crosslinked Resin?

This is where buyers either get it—or buy the wrong product.

Compared to standard 8% resin, FWXC010 offers:

• Better resistance to chlorine and oxidation
• Longer service life under harsh conditions
• Reduced bead breakage and fouling
• More stable performance in fluctuating water quality

Trade-off:

• Slightly lower flow efficiency vs 8% resin, but significantly higher durability

Frequently Asked Questions (FAQs)
