The Aramid Pulp is widely used in the friction and sealing industry mainly because of its performance and service life.

 The aramid fiber is mainly made of poly  | para-phenylene terephthalamide. According to a series of treatments and processing of terephthalamide. During the process of cutting, grinding, and suspending in water, the fiber is turned into pulp. It is obvious that the high strength, high temperature resistance, abrasion resistance and other high-quality properties of aramid fiber are stably reflected, and it also has a good grip force, a particularly obvious dispersion, and a good control of viscosity.

A product formed from aramid fibers is called aramid pulp. It weighs between five and thirty pounds per cubic foot or 0.08 and 0.5 grams per cubic centimeter. The fibers have a length that ranges from 1/16 to 5/16 inches, or 0.8 to 8 millimeters. Aramid pulp has a specific surface area of 2.4 to 4.8 square feet per pound or five to ten square meters per gram, depending on the length of the fibers.

The automobile sector frequently uses aramid pulp, which is created from fibrillated chopped fibers, for products including brake pads, gaskets, transmission papers, and adhesives. The fibrils can be peeled off during the production process and are tiny enough to be inhaled. However, shipping the pre-opened pulp is not a wise financial decision.

Long-chain polyamides are the basis of aramid fibers. The most typical kind is poly (para-phenylene-terephthalamide). They are light in weight, highly temperature resistant, and strong. They can therefore be used in protective clothing and the aerospace sector. However, while processing abrasives, para-aramid fibers have a tendency to spew small-d fibers into the air.

Terephthalic acid and para-phenylene diamine are polymerized to create aramid fiber. The copolymer is extruded or spun after being partially orientated into a liquid crystal. A cooling air jet is used to cool the filaments after the spinning process. The manufacture is finished with a washing and drying process. The finished item is a strong fiber.

The cellulosic fiber made from aramidi pulp is made up of several tiny fibers. Each one extends from the main stem of a longer, bigger fiber and has a diameter of around a micrometer. These fibers serve as hooks, grabbing nearby material.

There are numerous synthetic polyamides that can be used to create aramid fibers. The polyamides must have a high molecular weight in order to create fibers. At least 85% of the amide chain must be aromatic. Additionally, there must be two aromatic rings, which may be substituted or unsubstituted. There are some aramid fibers with two rings, one of which is replaced and the other is not.

Aramid pulps are useful in a variety of applications where reinforcement is necessary. Cellulosic fibers are a wonderful choice for items that need reinforcement. They can be mixed with other fibers, utilized in carpets, or produced into sheet products. These fibers are incredibly strong, resilient, and light.

Aramid fibers are frequently included in blends of dense-graded asphalt. Their usage in porous mixes hasn’t been properly investigated, though. Aramid fibers, however, are less likely to develop fibrils. These fibers can be added to porous asphalt mixtures to increase their abrasion resistance.

Aramid fibers are long-chain polyamides created synthetically. They can withstand powerful mineral acids and bases as well as chemicals. Textiles, biocomposites, and fiber-reinforced composites all use these fibers.

Cellulosic fiber that produces ash contains silicon dioxide. It is made by spinning silicon dioxide with viscose. The fibers are then subjected to an aluminum solution.

A composite material comprised of aramid fibers is known as aramid pulp. The fibers typically have a length of 0.8 to 8 millimeters and have a specific surface area per gram of five to ten square meters. In general, these fibers have a low density and weigh 0.08 to 0.5 grams per cubic centimeter.

Rubber compounds are reinforced by the addition of aramid pulp. The compound’s modulus, hardness, and tear resistance are all improved by the reinforcement. The compound’s abrasion resistance and modulus are both enhanced by the addition of aramid pulp. Additionally, it makes the material more stretchy.

Usually, air gap spinning has been used to produce the aramid fibers that are used to make compressed aramid pulp. However, other fibers may also be utilized if they are strong enough to survive the stresses involved in refining.

Rubber reinforcement frequently involves the use of compacted aramid pulp. Aramid fibers’ high modulus enables narrower cross sections, which lowers component weight. The rubber compound is therefore more deflection resistant. This is beneficial for gaskets and seals in particular because they frequently need to withstand blowout.

Aramid pulps can increase the friction coefficient and durability of friction materials in addition to being utilized in a range of applications. Aramid pulps may also be combined with other fibers to improve tribological performance. In the automobile sector, aramid pulps can help reduce high-frequency noise and increase friction coefficient.

We suggest that the storage aramid pulpshould be placed in a dry and non-humid environment, It can be stored at room temperature. We suggest that humidity 35~60% of the storage should be kept away from exposure to the sun, rain and other adverse environments.
