Best Practices for Storing and Maintaining Fluoropolymer Tubing

Imagine carefully procuring high-performance fluoropolymer tubing for crucial medical devices or aerospace projects, only to discover months later that the material's properties have degraded beyond usability. Such scenarios can cause significant project delays and financial losses. This article examines proper storage techniques to maintain fluoropolymer tubing integrity during storage periods.

While extruded fluoropolymer tubing doesn't carry an official expiration date, improper storage can compromise its performance. These materials boast exceptional chemical stability and aging resistance, but prolonged exposure to adverse conditions may still cause deterioration. Recommended storage practices include:

• Maintaining storage areas at stable temperatures
• Ensuring dry, well-ventilated environments
• Protecting from direct sunlight exposure
• Preventing contamination from dust, oils, or other pollutants

PTFE and FEP heat-shrink tubing conforming to AS23053 specifications maintains guaranteed dimensional stability for at least four years when stored properly. The standard requires that expanded inner diameter (ID) and recovered wall thickness remain within AS23053/11 and AS23053/12 tolerance ranges during this period.

The AS23053 standard establishes rigorous requirements for material properties, dimensional accuracy, performance characteristics, and testing methodologies. Compliant products typically demonstrate superior:

• High-temperature resistance
• Chemical inertness
• Electrical insulation properties

Surface-etched fluoropolymer tubing requires particular storage attention due to its chemically modified outer layer. The etching process creates electron-deficient surfaces that actively attract atmospheric molecules, potentially compromising adhesive bonding capabilities over time.

Optimal preservation methods include:

• Maintaining original sealed packaging until use
• Using light-blocking protective bags (standard with quality suppliers)
• Minimizing exposure to ambient air when opened
• Avoiding direct hand contact with etched surfaces

Implementing systematic inventory controls significantly reduces material degradation risks:

• Document production dates, receipt dates, and storage conditions
• Conduct regular stock inspections
• Perform material testing before use after extended storage

Proper storage protocols ensure fluoropolymer tubing maintains its exceptional properties throughout storage periods, preventing costly project disruptions while delivering reliable performance in critical applications.
