4. Product Details
(1) Environmental protection field: Lightweight flame-retardant polyimide filament is a typical application in the field of environmental protection as a high-temperature dust removal filter material. Since the lightweight flame-retardant polyimide filament can be spun to form a very high surface volume coefficient, it provides conditions for it to capture dust particles and improves the dust filtration efficiency. Coupled with the excellent heat resistance of lightweight flame-retardant polyimide filaments, lightweight flame-retardant polyimide filaments have become the best high-temperature filter materials at present. At the same time, as people pay more and more attention to the field of environmental protection, lightweight flame-retardant polyimide filament filter materials have considerable market prospects.
