Material Overview

### Description of hmpe ropes

HMPE ropes are produced with ultra high molecular weight polyethylene (UHMWPE) fiber and advanced technology. Featuring high strength, low weight and low elongation, they have a long service life, and their operation is easy, fast and safe.

### Features

* **Stronger:** with a same diameter, the strength of hmpe ropes is comparable to that of wire rope.
* **Lower elongation: **their breaking elongation is close to that of wire rope.
* **Lighter: **with a same strength, their weight(g/m) is only 1/8 of wire rope.
* **Material:**UHMWPE
* **Structure:**12 strand
* **Density: **0.97g/cm3
* **Melting point:** 140℃
* **Elongation: **3.5%
* **Abrasion resistance:** excellent
* **UV resistance: **excellent
* **Chemical resistance:** good
* **Dry and wet conditions:** wet strength equals dry strength
* Non-rotating and anti-kinking, longer service life
* Easy to handle, inspect and repair
*

### Application

port towing, mooring system for ultra large container ships, Army\&Navy equipment, offshore, aerospace, sport equipment, electrical communications, large precision object sling, etc.
