Para-aramid fiber is a high-performance synthetic fiber with excellent strength, heat resistance, chemical resistance and abrasion resistance. It is made by polymerization of paraphenylenediamine and terephthalic acid and has a highly crystalline structure, which enables it to maintain excellent performance under high temperature and high load.
Description
Product Features
- High Strength
Para-aramid fiber has a very high tensile strength, which is more than five times stronger than steel, allowing it to maintain stable performance under heavy loads.
- Heat Resistance
It has excellent high temperature resistance and can be used for a long time at temperatures up to 300°C (572°F), and it is not easy to degrade in high temperature environments.
- Chemical Resistance
Para-aramid fiber has strong tolerance to a variety of chemicals and can resist corrosion from chemicals such as acids, alkalis, and oils.
- Lightweight
Despite its ultra-high strength, para-aramid fiber is relatively light, making it particularly popular in applications that require weight reduction.
- Abrasion Resistance
The fiber has excellent wear resistance and can be used in highly abrasive environments, extending the service life of the material.
- Low Elongation
Para-aramid fiber has extremely low elongation, ensuring that it will not stretch under load, keeping the material stable in shape.
