POLYIMIDE Fiber

Quality characteristics

It's a high temperature resistant and flame retardant fiber. The application is similiar to meta-aramid. But PI fiber has its own advantages.

The long-term service temperature is 260℃. The decomposition temperature is 560℃. The LOI is 38%, it means it's none-flameble fiber.

UV resistant and radiation resistant. Far lower damage length under fire compared aramid fiber.

Applications

Polyimide fiber is applicable in many products, but it is used best in niche-applications with extreme standards for the material:

1- FR Protective clothing: e.g. military fligth clothing, flame resistand underwear, firefighter uniform etc.

2- High temperature filtration and industrial insulation: e.g. dedusting filtration for cement factories, steel or powder plants, air filtration for painting area operated at more than 300°C .

3- Composite material: taking advantage of insulation, flame retardance and high emperature resistance, chopped fiber can be used as reinforced material.
