Because of its low cost and utility as a general purpose rope, polypropylene is perhaps the most popular ropes on the market today.
Polypropylene rope will float, has excellent resistance to most common chemicals. It is also resistant to rot, mildew and deterioration. It has good abrasion and UV resistance, good strength, and moderate stretch. It is a perfect economical choice as a general purpose rope.
Hollow braid rope is an easily spliced cord of a diamond braid construction; most common in nylon or polypropylene. Constructed of 8, 12 or 16 strands, hollow braided rope is the same as the diamond braided rope on the surface, but is coreless. Because it does not have a core, it makes it easy to splice. Hollow braided rope is braided into a circular pattern with half of the strands going clockwise and the other half going counter clockwise. The strands can interlock with either twill or plain weave.
