- Product Description
-
PTFE piston sealing rings are high-performance sealing components widely used in demanding applications due to their exceptional chemical stability, low friction coefficient, and high-temperature resistance.
1. Key Characteristics
- Ultra-low friction coefficient(0.04~0.1): Ideal for high-speed or precision reciprocating motion, reducing energy consumption.
- Chemical inertness: Resistant to strong acids, alkalis, organic solvents, and nearly all industrial media (e.g., concentrated sulfuric acid, liquid oxygen).
- Wide temperature range: Stable operation from **-200°C to +260°C** (short-term exposure up to **300°C**).
- Non-stick property: Prevents material adhesion, ensuring easy cleaning.
- Self-lubricating: Operates effectively without external lubricants, suitable for dry or oil-free environments.2. Applications
- Chemical/Petrochemical: Reactors, pump/valve seals (corrosion-resistant).
- Semiconductor/Solar: High-purity vacuum chambers, wafer handling systems.
- Food/Pharma: FDA-compliant, used in sterile production lines.
- Aerospace: Fuel systems, hydraulic actuators (extreme-temperature resistance).
- Energy: Nuclear coolant pumps, wind turbine hydraulic pitch systems.3. Installation & Maintenance
- Pre-compression: Typically **10%~20%** (consider叠加 effects with elastomers).
- Avoid Sharp Edges: Use installation sleeves to prevent PTFE ring shearing.
- Cleanliness: Filter contaminants (PTFE is wear-resistant but vulnerable to hard particles).
