Commonly known as Teflon tubes, PTFE (Polytetrafluoroethylene) tubes are high-performance fluoroplastic pipes manufactured through a rigorous process of material mixing, blank pressing, cold extrusion and high-temperature sintering. Renowned as the "King of Plastics", PTFE tubes stand out in the industrial field with their unparalleled comprehensive performance, becoming the preferred choice for handling extreme working conditions that ordinary pipes cannot adapt to.
Core Performance Advantages
Extreme Chemical Corrosion Resistance
PTFE tubes possess outstanding chemical inertness, making them resistant to almost all strong acids, strong alkalis, strong oxidants, organic solvents and halogen media—including highly corrosive substances like aqua regia and hydrofluoric acid. They do not corrode, swell or pollute transmission media, fundamentally solving the problem of pipeline corrosion in harsh chemical environments, and greatly extending the service life of pipeline systems.
Wide Temperature Range Stability
With exceptional high and low temperature resistance, PTFE tubes can operate stably for a long time in a temperature range of -180°C to +260°C, with a short-term peak temperature resistance of up to 300°C. They remain tough without brittleness at ultra-low temperatures and do not soften or deform at high temperatures, perfectly adapting to cryogenic refrigeration, high-temperature fluid and steam transmission scenarios.
Non-Stick & Low-Friction Properties
Featuring an extremely low friction coefficient of only 0.04, the inner wall of PTFE tubes is smooth and non-stick, which greatly reduces fluid transmission resistance and pressure loss. It is not easy to scale, adhere to residues or block, realizing efficient fluid transmission. This self-cleaning property also eliminates cross-contamination of media and reduces the frequency of pipeline cleaning and maintenance.
High Cleanliness & Non-Toxicity
Produced with food-grade and pharmaceutical-grade PTFE raw materials, these tubes are non-toxic, odorless and free of harmful substance precipitation, fully complying with international standards such as FDA and GMP. They are widely used in hygienic transmission scenarios in food, beverage, dairy and pharmaceutical industries, ensuring the purity and safety of transmitted media.
Excellent Electrical Insulation
PTFE tubes have superior electrical insulation properties, with high dielectric strength, low dielectric loss and excellent arc resistance. They are ideal insulation and protection components for high-frequency, high-voltage, high-temperature and humid electrical and electronic equipment, ensuring stable operation of circuit systems.
Good Flexibility & Durability
The product has excellent flexibility and structural strength, can be bent freely to adapt to complex pipeline layouts without kinking or cracking. For high-pressure working conditions, steel wire or glass fiber braided reinforced PTFE tubes are available, which further enhance pressure resistance, tensile resistance and aging resistance, suitable for both fixed and dynamic pipeline systems.
