PTFE(Teflon) Balls

PTFE balls are high-performance engineering plastic spheres known for outstanding chemical inertness, an extremely low coefficient of friction, and a very wide service-temperature range. They are widely used as critical components in chemical, food, medical, electrical, and general industrial applications.

Key Properties

• Density: 2.2 g/cm³
• Water absorption (24 h): <0.01%
• Flammability: V-0
• Coefficient of friction: 0.05–0.2
• Hardness Rockwell: D50–55 (R58)
• Tensile strength: ~3,900 psi (~26.9 MPa)
• Elongation at break: 400%
• Operating temperature: -260°C to +260°C
• Chemical resistance: Resistant to almost all industrial acids, bases, solvents, and halogens

Typical Applications

• Check valves, pumps, fluid-control equipment, seals, and valve cores for corrosive chemicals.
• Food-processing equipment, pharmaceutical machinery, and medical devices.
• Electrical insulation in switches, connectors, and related components.
• Chromatography column packing, mixing beads, tribology studies, and extreme-environment testing.
• Light-load bearings, slide rails, float balls, mechanical transmission, and vibration damping.
