Conex® Staple Fiber

Conex® Meta-Aramid Fiber
Conex® meta-aramid fibers are best known for their combination of heat resistance and strength. In addition, meta-aramid fibers do not ignite, melt or drip, a major reason for their success in the fireproof apparel market. In comparison to commodity fibers, m-aramids offer better long-term retention of mechanical properties at elevated temperatures. Meta-aramids have a relatively soft hand and tend to process very similarly to commodity fibers, giving them a wide range of converted products.

Conex® High Tenacity (HT) type m-aramid has significantly higher tensile strength than that of other meta-aramids. This high strength allows it to bridge the gap between meta-aramid and para-aramid fibers for applications where added strength offers both technical and economic advantage.
