This specification covers a non-crosslinked polyvinyl chloride plastic in the form of flexible, thin-wall, heat-strinkable tubing with a low recovery temperature.These products have been used typically as a flexible, electrical insulation tubing whose diameter can be reduced to a predetermined size by heating to 150 degrees C (302 degrees F) or higher, but usage is not limited to such applications. This tubing is stable for continuous exposure from -20 to +105 degrees C (-4 to 221 degrees F).
