Bannor Polyimide
Bannor Polyimide is one of the dry-spinning polyimide fiber series products independently developed.
Bannor 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 300C, with a thermal decomposition temperature of more than 567C and no brittle breakage in liquid
nitrogen at -169℃.
Bannor 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 Bannor Polyimide fiber also have other excellent properties such as weather resistance, thermal insulation, chemical resistance, radiation resistance, UV resistance.
Flame retardant performance
The limiting oxygenindex
The limiting oxygen index (LO1) 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 ofPolyimide fiberpassed 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.
High Temperature Resistance
The long-term service temperature of Polyimidefiber is up to 260~300℃. Initial decomposition starts from 567℃, As raw material of filter bag, the good dimensional stability and strength retention under high temperature provide higher filtration efficiency and service life.
Weather Resistance and Chemical Resistance
Polyimide fiber has excellent resistance to radiation , acid, alkali and thermal oxidation.
It can keep outstanding mechanical property and chemical stability in the extreme environment such as space, sea, ice and desert.
Acid resistance
Radiation resistance
Military standard salt spray test
Using 100% polyimide yarn in accordance with GJB150A-2009 standard for neutral salt spray test.
Antibacterial Property
Antibacterial function
Polyimide fiber has natural antibacterial function. The antibacterial effect outperforms bamboo fiber.
Military standard fungus test
According to GJB150.10A-2009 military equipment laboratory environmental test method of fungus test showed that the Polyimide fabric without fungus growth.
Far IR Property
Far-infrared healthcare textile can promote blood circulation and metabolism,enhance immunity. Polyimide fabrics meet the national standard for the far-infrared healthcare product with a far infrared ray of 4~16μ m and normal emittance of 88%.
Thermal Insulation Property
As an effcient thermal insulation material, Polyimide fiber has a very low heat conductivity coefficient, and its thermal performance is higher than that of cotton, wool, silk and other traditional materials. The 210g/m’Polyimidefiber thermal insulation has a CLO value of 4.13 and a thermal resistance of0.64 m’·k/w, which is higher than that of 3M's Thinsulate™ with the same weight. It has been used in cold-proof clothing and quilts.
Electrical Insulation Performance
The dielectric constant of polyimide is 3.4, and the corona resistance is good(parameter from the publically reported data of polyimide materials).
Color fastness
Polyimide solution dyed woven fabric has passed the colorfastness test and the results outperform the aramid one.
Healthy environment protection
Polyimide fiber is environmentally friendly from manufactur
ring to end use, and has passed Oeko-Tex® Standard 100, meeting EU textile import requiren ments.
