Here are a few of the most common questions about heat shrinkable tubing, sleeving, extruded tubing and related products.

1. How can I avoid splitting with Heat Shrink Tubing?

Allow shrinkable tubing to recover at least 20% to avoid splitting. Be sure to use a heat-gun at the proper suggested temperature and always use a reflector on the heat-gun for even heat dispersion. Either too much heat or improperly distributed heat is usually the cause of split tubing, especially PVC.
