1. Overview
PTFE tube, also known as Teflon tube, is a high-performance special pipe manufactured by extrusion and high-temperature sintering with polytetrafluoroethylene resin, known as the "King of Plastics".
2. Core Advantages
1. Wide Temperature Resistance (-80℃~260℃)
Continuous working temperature ranges from -80℃ to 260℃, peak temperature up to 300℃.
Melting point 327℃, no softening at high temperature and no cracking at low temperature, suitable for steam, hot oil and cryogenic medium transportation.
2. Excellent Chemical Resistance
Resistant to strong acid, strong alkali, aqua regia, hydrofluoric acid, oxidants and most organic solvents.
Ideal for high-purity material transportation in chemical and pharmaceutical industries, non-precipitation and non-medium contamination.
3. Low Friction & Non-Stick Property
Friction coefficient only 0.04, self-lubricating with low flow resistance.
Inner wall prevents adhesion of colloid and slurry, anti-scaling, easy to clean.
4. Superior Electrical Insulation
High volume resistivity, stable insulation under high frequency and high voltage.
Widely used for wire harness sheathing, sensor casing and battery isolation.
5. Food Grade & Non-Toxic
Compliant with FDA and EU EC1935 standards, safe for food, beverage, pharmaceutical and drinking water equipment.
6. Outstanding Aging Resistance
Anti-UV, ozone and temperature cycling, stable performance for over 10 years outdoor use.
3. Main Applications
- Chemical Industry: Transportation of corrosive liquid and gas
- Food & Pharmacy: Sterile liquid, pure water and food slurry delivery
- Electronic Industry: High temperature insulating casing and wiring protection
- Hydraulic Machinery: Corrosion-resistant high-pressure pipeline
- New Energy & Semiconductor: High-purity chemical and ultrapure water conveying

5. Advantages & Disadvantages
Advantages
Wide temperature tolerance, strong corrosion resistance, low friction, good insulation, non-toxic and long service life.
Disadvantages
Higher price than ordinary plastic and rubber pipes; prone to deformation under long-term high pressure; requires professional connection installation.
6. Conclusion
With superior performance on temperature resistance, anticorrosion, insulation and sanitation, PTFE tubes are essential piping materials for industrial and high-end fields. Proper selection improves operation stability and reduces maintenance cost for various industrial scenarios.
