What brand of aramid fiber is known for its heat- and flame-resistant properties?

Nomex is well-known for its heat- and flame-resistant properties, making it a preferred material in environments where thermal protection is critical, such as firefighting and industrial applications. This aramid fiber has unique chemical structures that allow it to withstand high temperatures without melting or igniting.

Nomex is used in a variety of protective clothing, including suits for firefighters and industrial workers, because it helps prevent burns and provides a barrier against heat. Its resilience to heat and flame is a key factor in its effectiveness as a protective material in confined space rescue situations.

The other materials mentioned do not offer the same level of heat and flame resistance. Kevlar, while also an aramid fiber, is primarily designed for strength and ballistic protection rather than heat resistance. Nylon is a synthetic polymer that can melt under high temperatures, and rayon, although a fiber, does not provide the thermal protection required in high-heat situations.
