Can Aramid Fiber Packing Be Used in Food Grade or Potable Water Applications
2025-12-17
When selecting sealing solutions for the food, beverage, and pharmaceutical industries, the primary concern is safety. Engineers and plant managers must ask: can high-performance materials like Aramid Fiber Packing meet stringent health standards? The answer is a resounding yes, provided the packing is specifically engineered and certified for such sensitive duties. At Kaxite, we specialize in developing advanced sealing materials that do not compromise on performance or compliance. Our Kaxite Aramid Fiber Packing is designed to offer superior mechanical strength and durability while being perfectly safe for applications involving potable water and food contact.
Not all aramid packings are created equal. The key lies in the materials used in its construction. Our food-grade packing utilizes high-purity, heat-resistant Aramid Fiber lubricated and impregnated with FDA-compliant materials such as food-grade PTFE or specialized lubricants. This ensures no harmful substances leach into the process media.
Key Product Parameters for Food-Grade Compliance:
-
Material Composition: High-tenacity Aramid Fiber with FDA-listed PTFE impregnation.
-
Compliance Certificates: Complies with FDA CFR 21.177.1550 and NSF/ANSI 61 for potable water.
-
Temperature Range: -100°F to +550°F (-73°C to +288°C), ideal for cleaning-in-place (CIP) processes.
-
pH Range: Effective in media with a pH of 0-14, resisting acidic and caustic cleaning agents.
-
Applications: Centrifugal pumps, mixers, valves, and rotary equipment in food processing, dairy, breweries, and water treatment plants.

Aramid Fiber Packing FAQ
Q: How do I confirm if an aramid packing is truly food-grade?
A: Always request official documentation from the manufacturer. Look for a Certificate of Compliance stating adherence to FDA regulations (specifically CFR 21.177.1550) or NSF/ANSI 61 for drinking water. Kaxite provides these certificates with every batch of our food-grade packing for full traceability and peace of mind.
Q: Does food-grade aramid packing sacrifice performance for compliance?
A: Absolutely not. Kaxite's formulation maintains all the inherent advantages of Aramid Fiber Packing—exceptional tensile strength, excellent wear resistance, and thermal stability—while using certified safe lubricants. It performs reliably under the high temperatures and aggressive cleaning chemicals common in hygienic industries.
Q: Can this packing handle the high-speed rotation of a centrifugal pump?
A: Yes. The inherent robustness of the Aramid Fiber structure, combined with our specialized braiding technique at Kaxite, provides excellent dimensional stability and rotational flexibility. It is designed to withstand the friction and shaft speeds typical in centrifugal pumps for liquids like syrups, juices, or water.
