Aramid pulp is obtained after surface fibrinization treatment of aramid fibers. Its unique surface structure greatly enhances the adhesion of the mixture, making it highly suitable as a reinforcing fiber for application in friction and sealing products.

Aramid 1414 pulp is light yellow in color, with a fluffy texture. It has abundant fuzz, high strength, good dimensional stability, no brittleness, high temperature resistance, corrosion resistance, toughness, low shrinkage rate, good wear resistance, large surface area, and can be well combined with other substances. It is a reinforcing material with a moisture regain of 8%, an average length of 2-2.5mm, and a surface area of 8m2/g. It is used as a reinforcing material for gaskets, featuring good resilience and sealing performance, posing no harm to human health or the environment. It can be applied to sealing media such as water, oil, hydrocarbons, and medium-strength acids and alkalis, and the gaskets produced have excellent sealing performance and creep relaxation resistance.

Usually, less than 10% of the pulp needs to be added to obtain a product with a strength equivalent to that of a 50-60% asbestos fiber reinforced product. It is used to enhance friction, sealing materials and other finished products, and can be used as a substitute for asbestos in friction sealing materials, high-performance heat-resistant insulating paper and reinforcing composite materials.
