There is a preconceived notion in this article and the external link that heat shrink tubing is made of monomers and partially polymerized material. Then by heating the tube, it continues its polymerization. I believe this statement to be completely false.

I run a website called BuyHeatShrink.com http://www.buyheatshrink.com [1]. I pride myself in not only selling products, but educating my customers. I am interested in an open discussion on this subject. If I'm wrong, I'll happily correct the information on my site.

Back to the subject of incorrect information: If the material is partially polymerized or un-polymerized, how is it that a heat gun operating at a few hundred degrees fahrenheit can polymerize the material after 30 seconds exposure, but an extruder (used to make the tubing) can't polymerize the material at hotter temperatures for sometimes 8-10 minutes?
