Aramid characteristics
Jul 16, 2018

1.good mechanical properties

Meta-aramid is a flexible polymer with higher breaking strength than ordinary polyester, cotton, nylon, etc. It has high elongation, soft handfeel and good spinnability, and can produce short fibers and filaments of different denier and length. In the general textile machinery, different yarns are woven into fabrics, non-woven fabrics, and after finishing, to meet the requirements of protective clothing in different fields.


2.excellent flame retardant, heat resistance

Meta-aramid has a Limiting Oxygen Index (LOI) greater than 28, so it does not continue to burn when it leaves the flame. The flame retardant properties of the Newstar ® meta-aramid are determined by its own chemical structure and are therefore a permanent flame retardant fiber that does not degrade or lose flame retardant properties due to time of use and washing. Newstar ® meta-aramid has good thermal stability and can be used continuously at 205 ° C, and can maintain high strength even at temperatures above 205 ° C. Newstar ® meta-aramid has a high decomposition temperature, and will not melt or melt under high temperature conditions, and carbonization will start when the temperature is higher than 370 °C.


3.Stable chemical properties

The meta-aramid has excellent resistance to most chemicals, and is resistant to most high-concentration inorganic acids, and has good alkali resistance at room temperature.


4.radiation resistance

The meta-aramid has excellent radiation resistance. For example, under the long-term irradiation of 1.2×10-2 w/in2 ultraviolet rays and 1.72×108 rads of γ-rays, the intensity remains unchanged.


5.durability

The excellent aramid resistance and chemical resistance of the meta-aramid can be more than 85% of the original strength after 100 times of washing with the fabric of the Newstar ®
