Bronze-Filled PTFE Square Bars – Custom-Cut for Seals/Bearings

Key Features

• 10x More Wear-Resistant than pure PTFE (15-40% bronze filler)
• Extreme Temperature Range: -200°C to +250°C (Ideal for cryogenic/LNG valves)
• Zero Maintenance: Self-lubricating (μ≈0.1) with bronze transfer film
• Chemical Proof: Resists 98% acids/alkalis (Except molten alkali metals)
• Easy Machining: Custom-cut to ±0.1mm (Square/Rectangular bars available)

Applications 

① High-Pressure Seals

• Valve stem seals (Chemical plants)
• Hydraulic piston rings (≤30MPa static pressure)

② Wear-Resistant Parts

• Conveyor guide rails (Food processing)
• Bearing cages (Dry friction environments)

③ Electrical & Corrosive Environments

• Insulating supports (Semiconductor etching machines)
• Pump liners (HF acid resistance)
