Biafo Cord

Biafo cord is a flexible cord containing a core of high explosive PentraErythritol-TetraNitrate (PETN), which is covered with combination of various yarns and finally with an PVC/ LDPE coating. This process protects Biafo cord from extreme temperatures, water, oil or other elements and provides essential feature as tensile strength, flexibility and other handling characteristics. It can be initiated by use of a plain or an electric detonator.
