PTFE liners for bottle caps come in various types, each designed to meet specific sealing and chemical resistance needs. The primary options include PTFE-faced silicone liners, pure PTFE liners, and silicone liners, with PTFE liners being the most chemically inert and temperature-resistant. These liners are compatible with a wide range of chemicals, withstand extreme temperatures (from -200°C to +250°C for specialized versions), and are available in customizable sizes (24-414 mm) to fit different containers. Their applications span laboratories, industrial settings, and medical environments, offering reliable sealing solutions for corrosive substances and demanding conditions.
Key Points Explained:
-
Types of PTFE Liners for Bottle Caps
- PTFE-faced silicone liners: Combine the flexibility of silicone with the chemical resistance of PTFE, ideal for moderate chemical exposure.
- Pure PTFE liners: Offer the highest chemical inertness and temperature resistance, suitable for aggressive solvents and extreme conditions.
- Silicone liners: Less chemically resistant than PTFE but provide good elasticity for general-purpose sealing.
-
Chemical Resistance and Compatibility
- PTFE liners, including lamina ptfe, are highly resistant to acids, bases, and organic solvents.
- Detailed compatibility charts help users select the right liner for specific chemicals, ensuring safety and performance.
-
Temperature Stability
- Standard PTFE liners operate between -40°C to 180°C, while specialized versions (e.g., SSI PTFE caps) endure -200°C to +250°C.
- This makes them suitable for cryogenic storage, autoclaving, and high-temperature processes.
-
Customizable Sizing
- Available in diameters from 24 mm to 414 mm, with common sizes like 24 mm and 40 mm for lab vials and bottles.
- Custom designs accommodate unique container shapes or sealing requirements.
-
Applications Across Industries
- Laboratories: For storing corrosive reagents or sensitive samples.
- Industrial: Sealing chemical containers or process equipment.
- Medical/Pharmaceutical: Ensuring sterile, leak-proof closures for medications or biologics.
-
Advantages Over Alternatives
- Superior chemical resistance compared to silicone or rubber liners.
- Long-term durability in harsh environments.
- Flexibility in customization for specialized needs.
