PTFE Solid Резиновые мячи' Функции
PTFE has top-tier physical properties (insulation, temperature resistance, corrosion resistance, self-lubrication), but its mechanical properties are relatively weak (moderate strength, prone to creep, poor wear resistance). Therefore, the PTFE balls or seals used in the market are often modified PTFE (with added fillers) to compensate for its mechanical shortcomings.

PTFE balls applications
Valves & Pumps:Used as check valve balls and non-return valve sealing balls
Bearings & Guide Rails:Used in oil-free self-lubricating bearings, sliders, and guide rails due to its extremely. low friction coefficient.
Electronics & Insulation:Used as high-frequency insulators or shock-absorbing balls for electronic components.
Chemical & Fluid Control:Used for flow control balls in chemical pumps, resisting strong acids and alkalis.
Medical & Food:Used as rolling balls in food machinery or medical devices, as pure PTFE is non-toxic, odorless, and FDA-compliant.

Diameter tolerance: Deviation of measured vs. nominal diameter; ground balls ≈ ±0.003 in (±0.08 mm), precision ground down to ±0.03 mm.
Sphericity: Consistency of diameter in all directions (total error), ≈ 0.003 in for ground balls — rounder = more uniform seal.
Surface roughness: Surface smoothness (Ra/μin); smoother = less leakage and wear.
Mold line / flash: Grinding removes parting lines and flash to eliminate local leak paths.
Dimensional stability: Resistance to thermal expansion, media swell, and compression set.
