Description
PTFE special-shaped parts are manufactured from high-quality PTFE resin according to customer specifications, drawings, or custom requirements. These parts are produced through molding followed by machining or other specialized processes. PTFE profiled products can operate within a temperature range of -190°C to +260°C and are commonly used for electrical insulation, corrosion-resistant linings, bearing components, shaft seals, and lubrication materials. They find extensive applications in the chemical industry, mechanical sealing, bridges, power generation, aerospace, and electronics.
PTFE (Polytetrafluoroethylene) shaped parts are made from high-quality polytetrafluoroethylene resin and molded into blank materials based on product specifications.
Polytetrafluoroethylene (PTFE/Teflon) is one of the most widely used and versatile fluorinated plastics, known for its excellent properties such as resistance to extreme temperatures, corrosion, aging, non-stick characteristics, high insulation, and lubricity. It is extensively used in industries like chemicals, machinery, construction, power, aviation, and electronics, making it one of the ideal engineering materials in modern industrial development.
PTFE profiles offer exceptional heat resistance, capable of continuous use between 190°C and 260°C. They remain stable even at low temperatures without becoming brittle or melting at high temperatures.
Corrosion resistance: almost completely resistant to any chemical or solvent, providing protection against all types of chemical corrosion.
Atmospheric aging resistance: maintains performance even after long-term exposure to atmospheric conditions.
Non-adhesive: has the lowest surface tension among solid materials, preventing adhesion to any substance.
Insulation: exhibits strong dielectric properties with a dielectric strength of 10 kV/mm.
Lubrication and wear resistance: features a low friction coefficient, typically between 0.04 and 0.15, which makes it highly effective in reducing wear due to its natural lubricity.
Key Features
> Resistant to acids and alkalis > Chemically inert > Has the lowest friction coefficient among all pure materials > Non-stick and age-resistant > Custom molds can be created based on customer requirements.
Properties
We provide customized filled PTFE products tailored to specific application needs. Examples include glass fiber, carbon fiber, MoSâ‚‚, graphite, bronze, and pigments.
Product Description
Glass Fiber:
Enhances compressive strength, rigidity, and wear resistance. Reduces creep and cold flow. Minimal impact on chemical and electrical properties.
Carbon:
Improves compressive strength, hardness, wear, and load-bearing capacity. Good chemical resistance. Varying types and amounts of carbon can be added to adjust conductivity.
Boosts hardness, stiffness, and wear resistance. Minimal effect on chemical and electrical properties.
Bronze:
Increases hardness and wear resistance. Improves dimensional stability and compressive strength. Not suitable for corrosive or electrical environments.
