Dyneema: prestretched and heat set

[Beowulf]

Does anyone have a source for the dyneema that is prestretched and heat set? I hear it has better properties than standard SK75/78.

Trying to find sources, reviews, information....etc, but zero luck.

Just curious, What are you using it for?

It is my understanding the heat-setting and pre-stretching are processes used to deal with the air gaps in the rope from the looming process to help set a more consistent diameter with a smaller diameter. This smaller 'set' diameter line can be stronger in cross section than a line that has looming space still in it.

It also reduces elastic elongation even further ( which is already very low for synthetic winch lines )
