Sisal (Agave sisalana) and Henequen (A. fourcroydes) are the other two
major hard fibers. Henequen is sometimes called Mexican or Cuban sisal. The
various types of sisals are usually identified by country or origin. Brazil, Haiti, Kenya, Tanzania, and Indonesia, are all
major producers. Sisal and Henequen are resistance to salt water but are
relatively low in strength, about 80% that of manila. They are used primarily
for twines, small ropes, and cable insulations.
