The high-temperature resistance of Aramid 1414 is to that of Aramid 1313. Although both are high-temperature-resistant materials, their tolerance to temperatures differs significantly.
Comparison of High-Temperature Resistance
- Aramid 1414: Can remain undecomposed and non-melting at temperatures up to 560°C. Even under temperature conditions, it maintains the integrity of its molecular structure.
- Aramid 1313: The long-term service temperature limit is 220°C(maintaining stable performance for ten years), while short-term exposure can withstand 260°C (retaining 65% strength after 100 hours).
Differences in Chemical Structure:
Aramid 1414 has a rigid linear macromolecular structure (para-phenylene linkages), whereas Aramid 1313 has a zigzag structure with meta-phenylene linkages. The former exhibits higher thermal stability.
Divergence in Applications:
- Aramid 1313 is commonly used in high-temperature filtration and insulation materials (e.g., industrial dust filter bags, fireproof clothing).
- Aramid 1414 is employed in bulletproof armor, aerospace, and other scenarios requiring both high-temperature resistance and strength.
