Detailed Introduction
Polytetrafluoroethylene (PTFE) is a high-molecular polymer synthesized through the polymerization of tetrafluoroethylene, with the structural formula -[-CF₂-CF₂-]n-. It exhibits excellent chemical stability and corrosion resistance, making it one of the best corrosion-resistant materials available today. With the exception of molten alkali metals, chlorine trifluoride, chlorine pentafluoride, and liquid fluorine, PTFE is resistant to all other chemical substances—it remains stable even when boiled in aqua regia. It is widely used in various applications requiring resistance to acids, alkalis, and organic solvents. PTFE offers outstanding sealing properties, high lubricity, non-adhesiveness, electrical insulation, excellent aging resistance, and superior temperature tolerance. PTFE itself is non-toxic to humans.
The development of PTFE has solved numerous challenges in the chemical, petroleum, and pharmaceutical industries. PTFE seals, gaskets, and sealing washers are manufactured through molding processing using suspension polymerized PTFE resin.
Key Performance Features:
High Temperature Resistance — Operating temperature up to 250°C
Low Temperature Resistance — Excellent mechanical toughness; maintains 5% elongation even at temperatures as low as -196°C
Corrosion Resistance — Exhibits inertness to most chemicals and solvents; resistant to strong acids, strong alkalis, water, and various organic solvents
Weather Resistance — Best aging life among all plastic materials
High Lubricity — Lowest friction coefficient among solid materials
Non-Adhesiveness — Smallest surface tension among solid materials; does not adhere to any substance
Non-Toxic — Physiologically inert; can be implanted in the human body long-term as artificial blood vessels and organs without adverse reactions
Our company offers not only domestically produced PTFE but also imported brands including the M111/TFM series, among others.
2. Performance Improvements Through Filler Enhancement (Core Value)
Significantly Enhanced Wear Resistance: This is the most important improvement. Wear resistance can be increased by hundreds or even thousands of times compared to pure PTFE.
Notably Improved Compressive Strength and Creep Resistance: Capable of withstanding higher loads with minimal deformation under long-term pressure.
Increased Hardness, Rigidity, and Dimensional Stability.
Improved Thermal Conductivity (especially when adding metal or carbon-based fillers).
Reduced Linear Expansion Coefficient, resulting in more stable dimensions with temperature changes.
