The PTFE Tube from Chunhuan is a high-performance fluoropolymer product designed for transferring high-purity, corrosive, and ultra-clean fluids in demanding environments. With outstanding chemical resistance, ultra-low friction, and excellent electrical insulation, this tubing is the preferred choice for applications in chemical processing, semiconductors, pharmaceuticals, food, and mechanical industries.
Widely used in chemical, semiconductor, medical, food, and machinery industries for conveying high-purity chemicals, solvents, and ultrapure water through corrosion-resistant pipeline systems.
Available in pure PTFE (e.g., GP grade, electrical grade) or filled/molded PTFE with glass fiber, graphite, or carbon fiber reinforcement for enhanced mechanical performance.
Excellent Chemical Resistance: Resistant to nearly all known chemicals and solvents, including strong acids, alkalis, and oxidizers.
Low Friction & Non-Stick Surface: Ensures clean, complete discharge of viscous or sticky media, minimizing product loss and cross-contamination.
Superior Electrical Insulation: Ideal for protective conduit and electrical applications in harsh environments.
Wide Temperature Range: Maintains stability and flexibility from -200°C to +260°C, with short-term resistance up to 300°C.
High Purity & Biocompatibility: No additives, extremely low leachables and ionic extractables; suitable for semiconductor, biopharma, and food industries.
Flexible & Customizable: Available in a wide variety of sizes, wall thicknesses, and shapes (straight, conical, flanged) to suit specific system needs.
Continuous operation: -200°C to +260°C
Short-term tolerance: up to 300°C
Polytetrafluoroethylene (PTFE) — available in pure or modified filled grades.
Dependent on tube size, wall thickness, and temperature, generally suitable for low to medium pressure applications.
Chemical Processing: Transfer lines, liners, expansion joints, and pump linings for corrosive fluids.
Semiconductor Manufacturing: Transport of ultra-pure water, photoresists, and etching solutions.
Pharmaceutical & Biotechnology: Transfer of sterile liquids, fermentation media, and API solutions.
Food Industry: Conveyance of syrups, sauces, or viscous food materials in hygienic systems.
Automotive & Industrial Equipment: Used in fuel and brake systems, and as corrosion-resistant wire insulation.
Material: 100% pure PTFE or filled modified PTFE (glass fiber, graphite, carbon fiber).
Color: White (pure PTFE) or black/brown (filled grades).
Surface: Smooth, low-friction, and non-stick.
Certifications: Available with USP Class VI, FDA, and RoHS documentation upon request.
Processing Support: Precision CNC machining, molding, sintering, and custom fabrication according to drawings or samples.
The PTFE Tube by Chunhuan stands out as a highly durable, chemically inert, and pure fluid conduit solution. It ensures clean, contamination-free transport of aggressive or high-purity substances even under extreme temperatures. Its flexibility, non-stick surface, and electrical insulation properties make it indispensable in modern industries where safety, purity, and performance are critical.
