it Cuts Chilling Costs to the Bone it's a cold fact: Proper insulation is the key to low-cost storage and transportation at low temperatures. Being applied above to liquid carbon dioxide cars is a light weight hardboard made of expanded P L I O F L E X rubber which does a matchless job of efficiently a n d economically shutting cold, heat and moisture, in or out. Millions of tiny, closed cells — filled with nitrogen and bound by tough, hard rubber—give this board the lowest conductivity of any known structural material. It also is strong enough to be used in self-supporting construction, does not require a vapor barrier a n d c a n be easily cut to shape and installed.
Plioflex
When first introduced, this product was made from natural rubber. But wartime shortages caused a change to synthetic rubber which, because of its uniformity, soon proved to be much more satisfactory. PLIOFLEX is used today because of its unusually high uniformity and CHEMICAL consistently low moisture content.
