What Are The Uses And Characteristics Of Aramid
Published On: July 17, 2024 By: ray herb
Aramid is a natural flame-retardant fabric that has shown broad application prospects in multiple fields due to its unique physical and chemical properties. Also known as aromatic polyamide fiber, it is a high-performance synthetic fiber made by spinning special resins. Its molecular structure is unique, consisting of long chains alternately connected by amide bonds and aromatic rings. According to the differences in molecular structure, aramid is mainly divided into meta aramid (aramid I, 1313), para aramid (aramid II, 1414), and heterocyclic aramid (aramid III) in industry. So what are the uses and characteristics of aramid?
The use of aramid:
1. Long filament
2. Short fiber pulp
3. Paper
4. Fabric and composite materials
5. Aerospace
6. Military
7. Transportation
8. Communication
9. Tire
Types of aramid:
1. Neighbor aramid
2. Para aramid (PPTA)
3. Meta aramid (PMTA)
Advantages of aramid:
It has excellent performance, including high strength, high modulus, high temperature acid-base resistance, lightweight, insulation, anti-aging, stable chemical structure, safe combustion and long service life.
Disadvantages of aramid:
Poor light and ultraviolet resistance, not resistant to strong acids and alkalis, low compressive strength and modulus, low bonding strength between fibers and resin interface, poor moisture absorption, and easy hydrolysis.
