1. Maintained stable fiber properties under widen temperature range: Long-term using temperature at 280 ℃, 5% weight loss under thermal decomposition temperature is 573 ℃, cannot brittle under liquid helium at -269 ℃.

2. Excellent flame resistance: LOI is greater than 38%, permanent flame retardant. Also has non-melting properties, from the fire can be self-extinguishing, smoke rate is very low, non-toxic.

3. Excellent chemical stability: Polyimide fiber with its aromatic structure, withstanding varieties of common organic solvents and functions of compounds, making polyimide fiber with long service life.

4. Excellent electrical properties: At high temperature, high pressure, high humidity, frequency and under other conditions can still maintain good insulating properties.

5. Good filter performance: Polyimide fiber and superfine fiber, used alone or in combination, can increase the filtration surface area, and improve filtration efficiency.

6. Security: Polyimide fiber has passed the Swiss Textile Testing Institute test oeko-tex100, got the baby confidence level ecological textile certification, which is environmental to developed to baby products.

7. Good weather resistance: UV-resistant, easy to store.

   With its outstanding thermal stability and good chemical and physical properties, the polyimide fiber as extremely efficient filter material, plays an important role in the application field of the high temperature filter as well as effectively filters industrial combustion generated in the process of harmful gases, dust, smoke resistance, chemical corrosion and recovery of precious material.  It is widely used in cement plant, combustion coal-fired power plant, steel plant, waste incineration plants, smelters, chemical plants, car coating factory and other industries.
