There are two most practical types of aramid fibers: meta-aramid (full name "poly(m-phenylene isophthalamide), also known as aramid 1313) and para-aramid (full name "poly(p-phenylene terephthalamide), also known as aramid 1414). The two have similar chemical structures, but their performance is very different.
The most widely used one is aramid 1313, which has excellent high temperature resistance, insulation, and flame retardancy. In particular, its high temperature resistance is the most outstanding. It will only begin to decompose at a high temperature of 370 degrees Celsius and will only begin to carbonize at a high temperature of 400 degrees Celsius.
