PTFE hoses in industrial applications

PTFE hoses and their key characteristics.

Polytetrafluoroethylene (PTFE) has established itself as a high-performance polymer widely used in industrial hose applications. With its unmatched chemical resistance, superior thermal stability, and smooth properties, PTFE has significantly enhanced fluid transport systems across demanding industries such as pharmaceutical, chemical, food, and cosmetics, where aggressive substances are involved.

WHY PTFE HOSES STAND APRT. 5 key characteristics of PTFE lined industrial hose.

1. Chemical resistance

PTFE is nearly chemically inert, offering exceptional resistance to corrosive substances such as strong acids, alkalis and solvents. This makes it essential for applications in the chemical and petrochemical industries, where hoses are regularly exposed to aggressive agents.

2. Thermal stability

PTFE hoses withstanding a wide temperature range. Perfect for processes involving extreme temperatures, from very low to - or high-heat applications. Unlike many other polymers, PTFE retains its structural integrity, ensuring consistent performance even under thermal stress.

3. Low friction and Chemical Inertness

PTFE stands out for its exceptional chemical inertness, making it ideal for industrial hose applications. It resists nearly all chemical agents, with very few exceptions, such as certain alkali metals and reactive fluorine under extreme temperature and pressure conditions.

The smooth surface of PTFE reduces friction, facilitating fluid flow and minimizing pressure drops along the hose. TUDERTECHNICA’s high-quality extrusion process ensures PTFE lined hose with smooth and uniform surfaces, making cleaning easy and minimizing downtime for maintenance (this is particularly important in the pharmaceutical and food industries, where maintaining cleanliness and avoiding product residues is critical).

4. Superior flex life

PTFE hoses demonstrate superior flex life compared to others such as FEP and PFA. For instance, tests based on ASTM D2176 show that PTFE can endure over 1 million cycles, whereas materials like FEP (Fluorinated Ethylene Propylene) and PFA (Perfluoroalkoxy) fall short in terms of durability and flex endurance.

5. Compliance and Safety

Teflon ® PTFE hoses are designed in compliance with stringent regulations and standards making them suitable for critical applications in pharmaceuticals, food, and cosmetics, where purity and safety are paramount.
