Aramid is suitable for manufacturing flame-retardant fibers primarily due to the inherent properties conferred by its chemical composition and molecular structure.
Aramid is a type of aromatic polyamide fiber, where the amide bonds in its chemical structure are closely linked to the benzene rings. This unique chemical composition allows aramid fibers to maintain stability at high temperatures, making them less flammable. Additionally, the benzene rings in its molecular structure provide good thermal and chemical stability, further enhancing the fiber’s flame-retardant performance.
The flame-retardant properties of aramid fibers mainly stem from their high thermal stability and chemical inertness. In the event of a fire, aramid fibers can quickly form a dense char layer that effectively isolates oxygen and heat, preventing the further spread of flames. Furthermore, aramid fibers produce less smoke and toxic gases during combustion, which helps reduce the hazards posed by fires to both people and the environment.
In addition to their flame-retardant properties, aramid fibers also exhibit good environmental and safety characteristics. They do not contain harmful substances such as halogens and do not release toxic gases or corrosive materials during combustion. This makes aramid flame-retardant fibers increasingly applicable in today’s environmentally conscious landscape.
The flame-retardant performance of aramid fibers has been widely recognized and applied. Many international authoritative organizations and standards have conducted rigorous tests and certifications on their flame-retardant properties.

Aramid is a type of plastic known for its excellent heat resistance and high mechanical strength, also referred to as aromatic polyamide fiber material. According to different classification criteria, aramid can be divided into several types. Here is a detailed introduction to the different types of aramid:
Fully Aromatic Polyamide Fibers: In this type, all amide bonds are connected to aromatic rings, forming a stable long-chain structure.
Heterocyclic Aromatic Polyamide Fibers: In this type, some amide bonds are connected to aromatic rings while others connect to different heterocyclic structures, resulting in a more complex molecular structure.
Meta-Aramid (PMIA, 1313): The amide bonds in meta-aramid connect at the meta position of the benzene ring, meaning there is one carbon atom between adjacent amide bonds on the benzene ring. Meta-aramid exhibits excellent heat resistance and does not burn even in flames around 1500°C, making it widely used in firefighting suits and fire-resistant materials. Its representative resin material is poly-m-phenylenediamine.
