Meta-Aramid

Property Category

Characteristics And Advantages

Thermal Performance

● High Temperature Resistance: It can be continuously used at a temperature of 205°C. Even in a high-temperature environment above 205°C, it can still maintain relatively high strength. It only starts to carbonize at 370°C, and gradually becomes brittle, carbonizes, and finally decomposes at temperatures above 400°C. Moreover, it will not melt or drip at high temperatures.

● Strong Flame Retardancy: The limiting oxygen index (LOI) is between 29% and 32%. It belongs to a permanently flame-retardant fiber. It will not continue to burn after leaving the flame, which can effectively prevent the spread of the flame and reduce the fire risk.

Mechanical Properties

● High Strength: The breaking strength is generally between 3 - 6cN/dtex, which is much higher than that of ordinary fibers. It can provide good strength support for products, making them more durable.

● High Elongation: The elongation rate can reach 25% - 45%. When subjected to external tensile force, it can deform to a certain extent without breaking, endowing the finished products with good flexibility and impact resistance.

● Soft and Spinnable: It has a soft hand feel and good spinnability. It can be conveniently produced into short fibers with different finenesses and lengths, and can be made into different yarn counts on general textile machinery, and then woven into fabrics, non-woven fabrics, etc.

Chemical Properties

● Acid and Alkali Resistance: It has excellent resistance to most chemical substances. It can withstand most high-concentration inorganic acids and has good alkali resistance at room temperature. It can maintain its own performance without being damaged in different chemical environments.

● Good Corrosion Resistance: It has a good resistance to most chemical substances, can remain stable in a variety of chemical media, and is not prone to chemical reactions that lead to a decline in performance.

Electrical Insulation Performance

It has good electrical insulation properties and can be used for the insulation of electrical equipment, ensuring the electrical safety of the equipment during operation and improving the reliability and service life of the equipment.

Dimensional Stability

Under different environmental conditions, the dimensional change of meta-aramid is relatively small, and it can maintain a stable shape and performance. This is very important for some application scenarios with high requirements for dimensional accuracy.

Radiation Resistance

Its radiation resistance is extremely excellent. For example, its strength remains unchanged after being irradiated by γ-rays of 1.72×10⁸rads for a long time, and it can be applied to special environments with radiation.
