Polytetrafluoroethylene (PTFE) pipes with high and low temperature resistance, Teflon milky white PTFE pipes

PTFE pipes (polytetrafluoroethylene pipes) are indeed an “all - around player”. Its most prominent features are high - temperature resistance, corrosion resistance, low friction, electrical insulation, and anti - aging. It can almost cope with all kinds of extreme environments. Now, let me help you sort out its core advantages clearly:

I. Strong High - Temperature Resistance

• It has an extremely wide operating temperature range. It can operate stably from - 80℃ to 260℃, and can even withstand a short - term high temperature of 300℃.
• Its thermal decomposition temperature is as high as 415℃. It self - extinguishes within 0.3 seconds after the open flame is removed, ensuring high safety.

II. Top - Notch Corrosion Resistance

• It can resist almost all strong acids, strong alkalis, and organic solvents, including concentrated nitric acid and aqua regia.
• It has extremely strong chemical stability and will not be eroded or release harmful substances even after long - term use.

III. Low Friction Coefficient

• Its surface is extremely smooth, with a friction coefficient of only about 0.04, which is even smoother than an ice surface. It is suitable for transporting viscous fluids.
• It has good self - lubricating properties, low starting resistance, and smooth operation.

IV. Excellent Electrical Insulation

• It has an extremely high resistance and a low dielectric constant, making it a top - tier electrical insulation material.
• It is suitable for high - voltage environments, such as wire insulation layers and capacitors.

V. Anti - Aging and Weather Resistance

• Even when exposed outdoors for a long time, its performance will not deteriorate due to sunlight, wind, or rain.
• It is radiation - resistant, has low permeability, and a long service life.

VI. Other Practical Characteristics

• Non - stickiness: It has an extremely low surface tension and hardly adheres to any substance.
• Non - toxicity: It has strong physiological inertia, is non - toxic to organisms, and meets medical device standards.
• Non - flammability: Its limiting oxygen index reaches 95%, and it is almost impossible to burn in a normal atmosphere.

VII. Typical Application Scenarios

• Chemical Transfer: Used to transport highly corrosive media.
• Medical Field: As implantable catheters due to its high biocompatibility.
• Electronics and Electrical: For wire insulation layers, capacitors, etc.
• Food Processing: Ensures the purity of fluids and complies with safety standards.
