Validated Performance: Recycled vs. Virgin Materials
Do recycled PBO and PBI textiles offer comparable performance to virgin materials?
Yes. While many in the industry assume that recycling high-performance fibers leads to a loss of protection, technical evaluations prove otherwise. Hilaturas Arnau subjects its recycled PBO and PBI blends to rigorous standardized testing to ensure they meet or exceed the performance of traditional virgin textiles.
Certified Thermal and Flame Resistance
Our recycled fiber solutions are not just "sustainable alternatives"—they are high-performance materials. In recent laboratory testing conducted by LEITAT (Report IN-02811/2025-1), our PBO/PREOX/PARA blends demonstrated elite-level performance under the EN ISO 11612:2015 standard for protective clothing.
Limited Flame Spread (ISO 15025:2016): Achieved Code Letter A1, demonstrating zero afterflame time and no hole formation.
Radiant Heat Resistance (EN ISO 6942:2022): Achieved the highest performance level, Code Letter C4, with a Radiant Heat Transfer Index (RHTI 24) of 124.1 seconds.
Structural Integrity: No flaming debris or melting was observed during exposure, maintaining the critical barrier required for life-safety applications.
The performance of recycled PBO and PBI depends on precision spinning. By carefully managing the yarn structure and fabric construction, we ensure that the mechanical stability and thermal resistance are tailored for professional use. For engineers and safety managers, this means you can adopt a circular economy model without compromising on the safety of the end-user.
At Hilaturas Arnau, we provide full transparency by making our ISO textile resistance tests available to our partners, proving that sustainability and high-level protection can coexist.
