The difference between aramid pulp and aramid fiber
1. Definition of aramid pulp
Aramid pulp is a chemical fiber raw material with good flame retardant properties, chemical corrosion resistance and excellent mechanical properties. It is a polymer material polymerized from aromatic polymers. It has an extremely high melting point and glass transition temperature and can be used stably for a long time at high temperatures.

The difference between aramid pulp and aramid fiber mainly lies in the use and processing method. Aramid pulp is a chemical fiber raw material and is mainly used to produce aramid fiber, engineering plastics, heat-resistant coatings, packaging materials, etc. Aramid fiber is a synthetic fiber processed from aramid pulp and can be used to make various high-strength, high-temperature, and corrosion-resistant textiles, industrial sewing threads, filter materials, etc. In addition, aramid pulp has a large particle size and usually needs to be processed into aramid fibers after high temperature and high pressure molding. Aramid fibers can be directly made into the required fabrics or other products.
