Pre-oxygenated felt, a marvel of material innovation, is created by carbonizing acrylic (PAN) through an advanced process. This unique material serves as an intermediate product bridging the gap between acrylic and carbon fibers, offering remarkable high temperature resistance and inherent flame retardant properties. Here's how it differs from polyester: 1. Diverse body material composition. 2. Flame-retardant polyester incorporates flame retardant additives or blends with a flame retardant masterbatch, whereas pre-oxidized felt achieves its properties naturally through the carbonization of acrylic fiber (PAN). It stands as an intermediate marvel between acrylic and carbon fiber, boasting superior high temperature resistance and flame retardant capabilities. 3. The limiting oxygen index of pre-oxygenated yarn significantly surpasses that of polyester, ensuring enhanced safety. 4. Unlike polyester, which melts upon ignition, pre-oxygenated felt retains its integrity, offering unmatched fire safety.
