Creep life
4x more creep life
Generally speaking, ropes made from HMPE are sensitive to long-term loads, meaning that lines made with the material elongate proportionally over time. This is known as creep – a process that will ultimately limit the lifespan of a line.
FAQs
Q: How do mooring lines made with Dyneema® SK78 compare to generic HMPE alternatives when it comes to creep?
A: Mooring lines made with Dyneema® SK78 offer at least 4x longer creep lifetime than any HMPE fiber – helping to keep mooring ropes and lines in service for longer.
Q: What are the external factors that can influence creep life?
A: The creep life of HMPE fibers is influenced by the ambient temperature and the applied load. Very high loads or a high temperature will accelerate the creep process. Those made by Avient offer the highest creep life and the lowest rope weight.
Q: How can creep rates be predicted?
A: Over the course of a multi-year research program, Avient has developed the Creep Performance Tool, which takes into account parameters including: type of HMPE, temperature, time, and tension. With this model, Avient is capable of predicting creep rate and elongations, and estimating creep lifetime of all its applications made with Dyneema® SK78.
