Polyimide Fibers

Product Details

Polyimide Brief Introduction

Polyimide is a non-flammable fiber in atmospheric conditions. The LOl is above 38%. It is resistant to high and low temperatures and can be used for a long time below 300℃, with a thermal decomposition temperature of more than 567℃ and no brittle breakage in liquid nitrogen at -169℃.Polyimide fiber will carbonize without melt and drop in case of fire. The density of smoke is 1/200 of the airbus requirement. Products made of Polyimide fiber also have other excellent properties such as weather resistance,thermal insulation,chemical resistance, radiation resistance,UV resistance.

Polyimide Performance Advantages

Flame retardant performance

The limiting oxygen index

The limiting oxygen index (LOI) refers to the minimum oxygen volume fraction required to maintain complete combustion in a mixture of oxygen and nitrogen. As a new generation of high performance fiber，Polyimide fiber has better flame retardant performance than traditional special fiber, with LOl up to 38%.

Low damaged length incombustion test

In vertical combustion test under Chinese fire protection criteria XF10-2014, the damaged length of Polyimide fabric is 1/5 of the aramid IIlA fabric (the mainstream FR fabric). The test result is far above the standard for protective fabric.

Smoke toxicity

Polyimide fiber will carbonize without melt and drop in case of fire.

FR fabric made of Polyimide fiber passed the combustion test based on BSS7238,7239. There is ultralow smoke and non-toxic after carbonization.

The density of smoke is1/200 ofABD0031 airbus requirement. According to the smoke density test method of building materials decomposition (GBT8627-2007),the smoke density grade(SDR) of pure Polyimide felt is only 0.12, far lower than the smoke density grade of current building insulation materials.

Polyimide fiber is an wonderful material for confined space textiles, heat insulatin,home textile and protective products.
