PEX-a (Peroxide Cross-Linked Polyethylene) is the highest-performance PEX pipe, manufactured using the Engel method for superior molecular uniformity. It dominates premium plumbing, hydronic heating, and industrial applications due to its unmatched flexibility, temperature resistance, and longevity.
Key Properties of PEX-A Tube
| Property | Specification | Advantage vs. Other PEX Types |
| Temp Resistance | -40°C to 95°C (short-term 110°C) | Best for high-temp applications |
| Pressure Rating | 10 bar @95°C (PN10 standard) | Higher burst strength than PEX-b |
| Flexibility | Bend radius ≤5× pipe diameter | Easier cold-weather installation |
| Chlorine Resistance | Passes ASTM F2023 (100+ ppm Cl₂) | Longer lifespan in chlorinated water |
| Lifespan | 50+ years (under standard conditions) | Most durable PEX type |
Comparison with Other PEX Tube Types
| Feature | PEX-a | PEX-b | PEX-c |
| Cross-Linking | Peroxide (Engel) | Silane (Moisture Cure) | Electron Beam |
| Flexibility | Best (memory effect) | Moderate | Good |
| Temp Resistance | Highest (110°C) | 90°C | 95°C |
| Cost | Highest | Lowest | Medium |
