Applications

1. Temperature Resistance

High temperature resistance: Long-term use temperature range -269℃ ~ 300℃, instantaneous temperature resistance up to 500℃ (such as in electric arc flash scenarios).

Low thermal shrinkage rate: Thermal shrinkage rate <1% at 300℃, avoiding high-temperature deformation that leads to protection failure.

2. Flame Retardancy

Self-extinguishing: Limiting oxygen index (LOI) reaches 38~42.

No molten dripping: No molten dripping during combustion, avoiding secondary injuries.

3. Chemical Stability

Corrosion resistance: Resistant to strong acids (concentrated sulfuric acid, hydrochloric acid), strong bases (sodium hydroxide), and organic solvents (acetone, DMF).

Aging resistance: Performance is stable under ultraviolet and ozone environments, with a service life of 5~10 years.

4. Excellent Mechanical Properties

High strength: Tensile strength ≥100 MPa, wear resistance reaches 10,000 Martindale tests (ASTM D4966).

Lightweight: Density is only 1.4 g/cm³, 30% lighter than aramid, suitable for lightweight equipment.
