PTFE rods offer excellent high and low temperature resistance, enabling long-term stable operation in extreme temperatures ranging from -200°C to 260°C, without melting at high temperatures or cracking at low temperatures. It also offers exceptional chemical resistance, withstanding corrosion by strong acids, strong bases, strong oxidizers, and various organic solvents, with the exception of a few substances like molten alkali metals and chlorine trifluoride. It reacts with virtually no chemical substances, including molten alkali metals and chlorine trifluoride. Its extremely low coefficient of friction (approximately 0.04) and excellent self-lubricating properties enable low-resistance operation without the need for additional lubrication, while maintaining minimal wear. It also possesses excellent electrical insulation properties, with its dielectric constant and dissipation factor remaining stable in both high and low frequency environments, unaffected by humidity and temperature. Its non-stick surface resists adhesion to any substance, is non-toxic and odorless, and exhibits excellent aging resistance, with no noticeable degradation in performance even after long-term exposure to air, UV light, or ozone.
Suitable for pipe seals, valve cores, and reactor liner rods in the chemical industry; oil-free bearings, guide sleeves, and wear-resistant sliders in the machinery manufacturing industry; high-frequency insulation brackets, cable insulation sleeves, and microwave equipment components in the electronics and electrical industry; equipment guides and sealing gaskets (compliant with food contact safety standards) in the food and pharmaceutical industry; high-temperature components and hydraulic system seals in the aerospace industry; and corrosion-resistant and insulating precision components in the nuclear power and semiconductor industries. They demonstrate irreplaceable performance advantages in demanding operating conditions such as extreme temperatures, severe corrosion, and high insulation requirements.
