2. Domestic aramid fiber (representative of Yantai) and DuPont NOMEX can be regarded as one thing, which is pure and has higher technological requirements.
1 2 belongs to two products with different processes and different prices, so there is no comparability.
The price of polysulfonamide is unknown, and there is not much understanding in the market. At present, all meta-aramid fibers are used for transformer and motor insulation. Du Bang's monopoly on para-aramid fiber is the basic way to do fire insulation and bulletproof protection, and domestic aramid fiber is also being done now.
Integration: At present, only a few kinds of aramid fibers can be made in China, and the price is around 360 yuan /kg. The price of DuPont NOMEX ranges from 0.036mm-0.76mm to around 400-540 yuan/kg, and some models are thousands.
All counterpoint: Dupont Kevlar is the most expensive, and the specific quotation depends on the use. A suit of protective clothing costs hundreds of thousands. Domestic aramid fiber is much cheaper;
Because polysulfonamide is a mixture of para-25% and meta-75%, I don't know which category it belongs to, so it should be the cheapest. We do insulation, which is rarely heard.
