PAN precursor of carbon fiber - 50k

Compared with 12k carbon fiber, 50k carbon fiber has the following advantages:

Cost and efficiency

- Low production cost: The large tow characteristics of 50k carbon fiber make it produce more in a unit time during the production process, thus reducing the production cost. However, due to the thinner tow, the production process requirements of 12k carbon fiber are more stringent, the production efficiency is relatively low, and the cost is also higher.

- High processing efficiency: During the processing of 50k carbon fiber, operations such as laying and impregnation are relatively faster, which can improve production efficiency, shorten production cycle, and reduce processing costs. It is especially suitable for large-scale production.

Application range

- Large structural parts manufacturing: 50k carbon fiber is more suitable for manufacturing large structural parts, such as wind turbine blades, automobile bodies, etc. Its large tow characteristics can better meet the requirements of large components for material dosage and performance, which can improve production efficiency, reduce costs, and ensure the overall performance of products.

- Wide application in the industrial field: Due to its cost advantage and good comprehensive performance, 50k carbon fiber is more widely used in the industrial field. It can be used to manufacture various parts and equipment in the chemical, electronic, mechanical and other industries, such as transmission shafts, pressure vessels, electronic equipment housings, etc.
