How does paracord perform in wet conditions?

Water Absorption and Strength Loss

When exposed to water, paracord’s nylon core absorbs moisture, leading to a gradual loss of tensile strength. The rate of absorption and strength loss depend on the temperature and duration of exposure. For example, a 550 lb paracord strand can lose up to 30% of its strength after being submerged in water at 20°C (68°F) for 8 hours.

Effects on Knot Security

Wet paracord can also lead to reduced knot security due to the loss of friction and adhesion between the strands. To mitigate this, it’s essential to dry the paracord as soon as possible, or use a backup knot or lash to ensure a secure connection. Additionally, using a cordage lubricant or wax can help maintain knot security in wet conditions.

Practical Considerations for Use in Wet Environments

When using paracord in wet environments, it’s crucial to consider the expected duration of exposure and the potential consequences of strength loss. In situations where high loads or stresses are anticipated, alternative cordage options with improved water resistance, such as Kevlar or Dyneema, may be a better choice. In general, paracord can still be a reliable option in wet conditions, but users should be aware of its limitations and take steps to mitigate potential risks.
