PTFE O-RING
Introduction to PTFE O-Rings
PTFE O-Rings:
Known for outstanding chemical resistance, high temperature endurance, and low friction. Ideal sealing solution for use in chemical, food, semiconductor, and automation industries. Enhances system efficiency and reduces maintenance costs.
Applications
- Chemical and pharmaceutical industries
- Semiconductor processes
- Food and beverage processing
- Automation systems
Lanshiuon Industrial Co., Ltd. provides high-performance, reliable PTFE O-Ring solutions for various industries.
| Property | PTFE O-Ring | Rubber O-Ring | PFA Encapsulated O-Ring (316L Spring) |
|---|---|---|---|
| Chemical Resistance | Excellent (resistant to most chemicals) | Moderate (depends on rubber type) | Excellent (PFA provides full barrier) |
| Temperature Range | -60°C to +260°C | -40°C to +200°C | -60°C to +200°C |
| Elasticity & Compression Set | Low (requires design compensation) | High (good sealing rebound) | High (316L spring supports recovery) |
| Friction Coefficient | Very low (excellent sliding) | High (wear-prone) | Medium (PFA exterior with spring core) |
| Cleanliness Level | High (ideal for semiconductor use) | Moderate (can attract particles) | Ultra-high (suitable for ultrapure processes) |
| Wear Resistance | Good (non-elastic contact type) | Moderate (varies by application) | Good (PFA shell is wear-resistant) |
| Metal Corrosion Protection | None (fully polymer) | None (fully elastomer) | Yes (316L stainless steel spring) |
| Recommended Use | Semiconductor, food, chemical, vacuum equipment | General sealing, low-pressure applications | High purity chemicals, vacuum, high pressure |
