Teflon balls, made from polytetrafluoroethylene (PTFE), are highly versatile components prized for their exceptional chemical resistance, thermal stability, and mechanical properties. These balls are waterproof, non-porous, and can be customized to any size through machining or molding. Their inert nature makes them resistant to almost all chemicals, including caustic substances, while their wide operating temperature range (-200°C to 260°C) ensures reliability in extreme environments. Additionally, Teflon balls exhibit low friction, self-lubricating properties, and excellent durability, making them ideal for seals, bearings, and other demanding industrial applications.
Key Points Explained:
-
Chemical Resistance & Inertness
- Teflon balls are composed of carbon and fluorine atoms, creating an extremely stable molecular structure. This makes them inert to most chemicals, including acids, bases, and solvents. Only alkali metals can break them down.
- Their non-porous, waterproof nature prevents absorption or reaction with liquids, ensuring long-term performance in corrosive environments.
-
Thermal Stability
- They operate reliably across a broad temperature range (-200°C to 260°C), with a melting point of 327°C (621°F).
- Heat deflection temperature of 120°C (248°F) allows sustained use in high-heat applications without deformation.
-
Low Friction & Non-Stick Properties
- A coefficient of friction as low as 0.110 enables smooth, self-lubricating movement, reducing wear and energy loss.
- Non-stick surface prevents material buildup, ideal for seals and bearings in food processing or pharmaceutical equipment.
-
Mechanical Strength & Durability
- Tensile strength ranges from 2,990 to 4,970 psi, with a flexural strength of 2,490 psi, ensuring resilience under load.
- Shore hardness of 55D and excellent ductility allow flexibility without cracking, even in dynamic applications.
-
Customizability & Versatility
- Can be machined or molded into any size or shape, adapting to specific industrial needs.
- Used in seals, bearings, valves, and non-stick components due to their corrosion resistance and maintenance-free operation.
-
Electrical & Physical Properties
- Dielectric constant of 2.1 makes them suitable for insulating applications.
- Minimal water absorption (0.01% over 24 hours) ensures dimensional stability in humid conditions.
