Polyethylene rope is a versatile solution for outdoor and marine applications. It has several key properties, including resistance to abrasion, UV rays, rot, and water. It maintains its shape and strength when wet, is buoyant and non-absorbent, and can absorb shocks. Ropes are available in a diameter range of 2mm to 36mm, while three-strand polyethylene ropes are commonly used for commercial, marine, and fishing purposes.
