This specification covers a crosslinked polyvinyl chloride plastic in the form of flexible, thin-wall, heat-shrinkable tubing. Primarily for use as a flexible, electrical insulation tubing whose diameter can be reduced to a predetermined size by heating to 175 degrees C (345 degrees F) or higher. This tubing is stable for continuous exposure from -20 to +105 degrees C (-5 to +220 degrees F).
