The application of UHMWPE in deep-sea platform positioning ropes is becoming increasingly widespread. UHMWPE has many excellent properties. Firstly, UHMWPE has high strength and wear resistance, stronger and more wear-resistant than many metals.

Secondly, UHMWPE can maintain good performance at extremely low temperatures, making it suitable for use in deep-sea environments. In addition, UHMWPE also has excellent corrosion resistance, which can prevent the influence of seawater and other corrosive substances. Finally, UHMWPE has a low coefficient of friction and good self-lubricating properties, making it advantageous in various scenarios where low friction is required.

However, UHMWPE has poor UV resistance, and prolonged exposure to UV radiation can lead to a decline in its performance. Moreover, its hygroscopicity is high, which may also affect its stability in marine environments.

Radiation modification is a method of inducing chemical or physical changes in the molecular chains of a material through radiation, such as gamma rays, electron beams, or X-rays.

For UHMWPE, electron beam is a commonly used irradiation source. This method greatly improves certain properties of UHMWPE, such as UV resistance, wear resistance, corrosion resistance, etc.

Dyneema's UHMWPE fibers have extremely high strength and wear resistance, moisture resistance, UV light resistance, and chemical resistance. The modified UHMWPE ropes are widely used by Dyneema in deep-sea engineering and other demanding scenarios.
