Recently, China's leading aramid fiber technology company, YTTH aramid fiber technology Group, has made a new breakthrough in the research and development of high model para aramid fiber technology, realizing the large-scale production of high-performance differential products, further expanding the product structure of para aramid fiber, and breaking the long-term monopoly abroad.
High strength para aramid fiber is widely used in safety protection, aerospace, bulletproof and other fields due to its excellent tensile properties and flame retardancy;
High modulus para aramid fiber is widely used in the protective layer of communication optical cable and other electronic products due to its high modulus, strong bending resistance and non-conductive material insulation.
YTTH has focused on key processes such as dissolution, polymerization, dry jet wet spinning, and high temperature setting, and has studied and conquered key core technologies such as homogenization of high molecular weight PPTA spinning stock solution, multi-stage drying of high modulus para aramid fibers, and high temperature setting. It has improved the process control technology of modulus while improving fiber strength.
The company adopts advanced high-precision equipment, which can enhance the process control ability in the large-scale production process, effectively reduce the difference between batches, and improve the stability and output rate of products.
At present, the company's high-strength para aramid fiber products and high model para aramid fiber products have achieved commercial production, and the annual output is more than 2000 tons.
The product performance indicators have all reached the same level abroad, meeting the market's requirements for lightweight, high strength and high specific modulus, and further improving the equipment processing and manufacturing level of China's aramid raw materials upgrading.
