- Peak temperature: 240°C (≤30 minutes)
Outstanding Mechanical Strength:
- Tensile strength up to 1500N/5cm
- 10x more abrasion-resistant than standard synthetic fibers
Stable Chemical Properties:
- Resistant to weak acids/alkalis (pH 4-9)
- Excellent hydrolysis resistance
Superior Filtration Performance:
- Filtration efficiency ≥99.99%
- 20% lower pressure drop than fiberglass bags
